Abstract—In recent research, composites are used because of low weight and high thermal performances. To reduce

weight and improve fuel efficiency, the aero industry has dramatically increased the use of aluminum composites in

recent years. Aluminum alloy based metal matrix composites (MMCs) with ceramic particulate reinforcement have

shown great usage for such applications. These materials having a lower density compared to the conventionally

used grey cast irons are expected to result in weight reduction of up to 50 – 60 %. In this study, attempt has been

made to analyze a new composite material called cenosphere reinforced aluminum alloy. The Aluminium-

Cenosphere composite material which has low thermal expansion and greater wear performance most extreme

conditions can be used in the places were wearing is a major problem.

Abstract

— This paper briefly discusses the new type of flow control method to increases the performance enhancement of aircraft. The purpose

of these research is to investigate the flow characteristics over an airfoil to control the flow separation control of co-flow jet (CFJ) airfoil by

Numerical Method. The concept of CFJ airfoil is to open an injection slot near leading edge and suction slot near trailing edge. This

mechanism that follows is that, high pressure air is injected tangentially along the span at the leading edge while a low pressure source

removes the same amount of air at the trailing edge. CFJ airfoil blows and sucks the same amount of mass flow, this creates so called Zero-

Net-Mass-Flux (ZNMF) flow control, the results obtained upon performing the experiments indicated co-flow jet airfoil with injection and

suction slot has better performance characteristics.

Abstract- MapReduce is a programming model which is an associated implementation for processing and generating large

datasets with a parallel, distributed algorithm on a cluster. A MapReduce cluster employs a master-slave architecture where one

master node manages a number of slave nodes. To implement the MapReduce tasks on cluster system, Hadoop framework is

used. It is a scalable, open source for data storage and processing. G-Hadoop is an extension of Hadoop that reuses the job

mechanisms of Hadoop and is designed for multiple clusters. The security framework based on security solutions such as public

key cryptography and SSL protocol simplifies the users authentication and job submission process. In addition the AES

algorithm is used to protect the proxy credential from the most common attacks.

ABSTRACT

Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data

among themselves without the reliance on a fixed base station or a wired backbone network. MANET nodes are typically

distinguished by their limited power, processing, and memory resources as well as high degree of mobility. In mobile ad hoc

network there are several routing algorithms, which utilize topology information to make routing decisions at each node. In

geographic routing, nodes need to maintain up-to-date positions of their immediate neighbors for making effective forwarding

decisions. Periodic broadcasting of beacon packets that contain the geographic location coordinates of the nodes is a popular

method used by most geographic routing protocols to maintain neighbor positions. We contend and demonstrate that periodic

beaconing regardless of the node mobility and traffic patterns in the network is not attractive from both update cost and routing

performance points of view. We propose the Adaptive Position Update (APU) strategy for geographic routing, which

dynamically adjusts the frequency of position updates based on the mobility dynamics of the nodes and the forwarding patterns

in the network. APU is based on two simple principles: 1) nodes whose movements are harder to predict update their positions

more frequently (and vice versa), and (ii) nodes closer to forwarding paths update their positions more frequently (and vice

versa). Our theoretical analysis, which is validated by NS2 simulations of a well-known geographic routing protocol, Greedy

Perimeter Stateless Routing Protocol (GPSR), shows that APU can significantly reduce the update cost and improve the routing

performance in terms of packet delivery ratio and average end-to-end delay in comparison with periodic beaconing and other

recently proposed updating schemes. The benefits of APU are further confirmed by undertaking evaluations in realistic network

scenarios, which account for localization error, realistic radio propagation, and sparse network.

ABSTRACT: A Wireless sensor network(WSN) consists of large numbers of sensor nodes with data processing, sensing and

communication capabilities. The main constraint on sensor network is battery power utilization, which affects the

communication between nodes. Hence to increase the lifetime of sensor node, an efficient energy saving protocol are needed.

The multihop-routing protocol is well known for power saving in data gathering.Recently several researchers used cluster-

based (LEACH), chain-based (PEGASIS), and tree-based (TREEPSI) protocols to energy efficient protocol.In this paper, a

novel Tree-clustered protocol has been proposed that combines the features of tree-based and cluster-based architecture. The

tree-clustered protocol gives better performance than other methods.

KEY WORDS: Wireless sensor network (WSN),energy efficient, multihop routing protocol.

ABSTRACT-Sclera and finger print vein is a new parallel vein recognition method using a two-stage parallel approach for

registration and matching. First, we designed a rotation- and scale-invariant Y shape descriptor based feature extraction method

to efficiently eliminate most unlikely matches. Second, we developed a weighted polar line sclera descriptor structure to

incorporate mask information to reduce GPU memory cost. Third, we designed a coarse-to-fine two-stage matching method.

Finally, we developed a mapping scheme to map the subtasks to GPU processing units. The experimental results show that our

proposed method can achieve dramatic processing speed improvement without compromising the recognition accuracy. We

examine the previously proposed finger-vein identification approaches and develop a new approach that illustrates its

superiority over prior published efforts. We develop and investigate two new score-level combinations i.e., holistic and

nonlinear fusion, and comparatively evaluate them. With more popular score-level fusion approaches to ascertain their

effectiveness in the proposed system. The project is a state-of-the-art advancement of multi biometrics, offering an original

viewpoint on features fusion. In greater detail, a frequency-based approach results in an identical biometric vector incorporate

sclera vein and fingerprint vein data. Consecutively a hamming-distance-based matching algorithm deals with the combined

homogenous biometric vector. The proposed multimodal system achieves interesting results with several commonly used

databases.

Abstract- Web injection attack exploits web application security by inserting malicious script into the web application. The

need for this kind of attack is to gain access to application data or database. Here the focus is on securing web application

against web injection attacks. To detect injection vulnerabilities in web services, we use combinatorial interaction testing the

main focus is on Cross-Site Scripting Attack (XSS). By analyzing the behavior of the Web service the model can detect the

presence of the injection vulnerabilities. This proposed work combines persuasive cued click points and password guessing

resistant protocol to reduce the guessing attacks as well as motivate users to select more random and difficult passwords to

guess. An algorithm for anonymous sharing of private data among parties is been developed. Assigning ID numbers to nodes

ranging from 1 to n, the identity received are unknown to the other member. Using serial number assigned the complex data can

be shared. The new algorithms are built on top of a secure sum Security operation using service discovery identities and id’s

vulnerability detection secured protocol.

ABSTRACT: Big data is a popular term used to describe the exponential growth and availability of data, both structured and

unstructured. The explosive growth of demands on big data processing imposes a heavy burden on computation, storage, and

communication in data centers, which hence incurs considerable operational expenditure to data center providers. Therefore,

cost minimization has become an emergent issue for the upcoming big data era. Different from conventional cloud services, one

of the main features of big data services is the tight coupling between data and computation as computation tasks can be

conducted only when the corresponding data is available. As a result, three factors, i.e., task assignment, data placement and

data movement, deeply influence the operational expenditure of data centers. In this paper, we are motivated to study the cost

minimization problem via a joint optimization of these three factors for big data services in geo-distributed data centers. To

describe the task completion time with the consideration of both data transmission and computation, we propose a two-

dimensional Markov chain and derive the average task completion time in closed-form. Furthermore, we model the problem as

a mixed-integer non-linear programming (MINLP) and propose an efficient solution to linearize it.

Dept of CSE, Sembodai Rukmani Varatharajan Engineering College, Sembodai, Nagappattinam,, Tamil nadu,

ABSTRACT: The development of parallel and distributed systems has drawn the attention of the research community to study

their scheduling performance. Since workloads are required to serve as the input of scheduling evaluation, workload models are

essential for researchers to generate synthetic workloads. Two kinds of workloads: real workloads (traces) collected from real

systems, and synthetic workloads generated by statistical models. The main objective of a workload model is

representativeness, which depends on the modeling approach. We provide a realistic model that incorporates up to five

important workload properties at the same time. The scope of our model is for rigid jobs which do not change their requested

number of processors at runtime. A job consists of 3 attributes: the arrival time of the job, the runtime indicating how long the

job is executed, and the parallelism indicating how many processors the job requests. In practice, We validated our model by

comparing and fitting with real data, and by comparing simulation results of scheduling with real and synthetic workloads.

First, it helps to evaluate new scheduling algorithms. Second, it can be used to evaluate the impacts of individual workload

features on scheduling. Third, it is useful for evaluating the impacts of interactions of workload features on system

performance.

ABSTRACT - Sensor networks come in a wide variety of forms, covering different geographical areas, being sparsely or

densely deployed, using devices with a variety of energy constraints and implementing an assortment of sensing applications.

Congestion in Wireless Sensor Network (WSN) can cause missing packets, low energy efficiency and long delay.Some

applications need to transmit large volumes of data concurrently from several sensors. These applications have different delay

and QoS requirements. Congestion problem is more urgent in such applications. To address this challenge, we propose a novel

which comprises three mechanisms:congestion detection using dual buffer thresholds and weighted buffer difference ;Flexible

Queue Scheduler for packets scheduling; Bottleneck-node-based source sending rate control scheme. Simulations show that

ECODA achieves efficient congestion control and flexible weighted fairness for different class of traffic. Therefore it leads to

higher energy efficiency and better QoS in terms of throughput, fairness, and delay.

Abstract--- Denial-of-Service attack is an attempt to make a system, machine or network resources unavailable to its user by

blocking or denying the services. The affected computer may crash or disconnect from the internet either permanently or

temporarily. The challenge of attack is to quickly and effectively identify incoming traffic as malicious. Hybrid detection

mechanism is used to detect the attack more accurately. It is the combination of misuse based detection and anomaly based

detection for accurate network traffic characterization and that reduces the false alarm rate. The detection rate is improved by

considering various parameters are Time, Speed, Distance and Packet size for finding the normal traffic. Denial of service

attack detection system that uses Multivariate Correlation Analysis for accurate network traffic characterization by extracting

the geometrical correlations between network traffic features and enhance the speedup of the process using triangle area based

technique.

Energy-Efficient HYBRID Communication Scheme for Mobile Ad Hoc Networks

G.ABIRAMI,S.Sindhu P.Suvitha S.Kavya N.Shobajebarani

Abstract: In mobile ad hoc networks (MANETs), every node overhears every data transmission occurring in its vicinity and

thus, consumes energy unnecessarily. However, since in some modern MANET routing protocols such as load distribution

based approach is not sufficient for high energy saving due to consumption of energy during inactive mode. Thus, we propose a

Localized Energy Aware Routing (LEAR) protocol along with sleep/ power-down approach. It increases the energy

conservation for transmitting data. Here we used SPAN protocol for selecting the master slave node. In proposed scheme shows

the better results in energy conservation.

Key words-MANET, LEAR, SPAN, sleep/power down approach.

Abstract---We analyze the error performance of the physical layer network coding (PNC) protocol with transmit diversity in

bidirectional relay networks for binary phase shift keying (BPSK) over Rayleigh fading channels. It is assumed that a

bidirectional relay network consists of two sources at transmitter and two sources at receiver and a relay consists of two

antennas, where each source node has a single antenna and operates in a half duplex mode, and the PNC over finite GF(2) is

employed. In this system, since the signal estimation of the multiple access channel (MAC) at the relay is given by the sum of

two exponential functions. Then relay transmit in the form of transmit diversity (alamouti) to the source. Then finally we derive

the capacity for system model. Finally we obtain outage probability, outage capacity for the end to end average bit error rate.

Abstract- We consider a scenario where nodes in a MANET disseminate data chunks using rateless codes. Any node is able to

successfully decode any chunk by collecting enough coded blocks from several other nodes without any coordination. We

consider the problem of identifying malicious nodes that launch a pollution attack by deliberately modifying the payload of

coded blocks before transmitting. It follows that the original chunk can only be obtained if there are no malicious nodes among

the chunk providers. In this paper we propose SIEVE, a fully distributed technique to infer the identity of malicious nodes. A

node creates what we termed a check whenever a chunk is decoded; a check is a pair composed of the set of other nodes that

provided coded blocks used to decode the chunk (the chunk uploaders) and a flag indicating whether the chunk is corrupted or

not. SIEVE exploits rateless codes to detect chunk integrity and belief propagation to infer the identity of malicious nodes. it

periodically runs the belief propagation algorithm on its factor graph to infer the probability of other nodes being malicious. We

show by running detailed simulations using ns-3 that SIEVE is very accurate and robust under several attack scenarios and

deceiving actions. We discuss how the topological properties of the factor graph impacts SIEVE performance and show that

nodes speed in the MANET plays a role on the identification accuracy. Furthermore, an interesting trade-off between coding

efficiency and SIEVE accuracy, completeness, and reactivity is discovered. We also show that SIEVE is efficient requiring low

computational, memory, and communication resources.

Abstract: Smart card is one of the greatest achievements in the world of information technology. Smart cards have many

applications such as health, ID verification and access control, electronic purse card, banking card, payphone card, passport

card and license card. Since, there are many kinds of smart cards, it is difficult to carry and protect them. Losing one card

means losing a lot of important information. As everyone knows, carrying and protecting one smart card is easier and more

comfortable than carrying two or more smart cards. Multipurpose smart card is a smart card with many different applications in

one smart card. Multipurpose smart card would be giving all services and making data processing and data transfer more

efficient and secure. We choose three most important cards such as health card, aadhaar cards and passport cards to be

combined in one smart card and find an encryption method to make it enough secure. It should also be efficient in transferring

information. The advanced encryption standard algorithm should be effective encryption system for these three applications in a

Abstract--Computer vision-based food recognition could be used to estimate a meal’s carbohydrate content for diabetic

patients. It proposes a methodology for automatic food recognition, based on the bag-of-features model. An extensive technical

investigation was conducted for the identification and optimization of the best performing components involved in the Bag-of-

features architecture and also the estimation of the corresponding parameters. A visual dataset with nearly 5000 food images

was created and organized into eleven classes for the design and evaluation of the prototype system. The optimized system

computes dense local features by using the scale-invariant feature transform on the Hue Saturation Value color space, builds a

visual dictionary of 10000 visual words by using the hierarchical k-means clustering and finally classifies the food images with

a linear support vector machine classifier. The system achieves 78% of the classification accuracy, thus proving the feasibility

of the proposed approach in a very challenging image dataset.

Abstract: A major issue of great concern in student modeling is the inherent uncertainty that exist due to

lack of sufficient information with high degree of certainty to build this model. The proposed system

presents a novel approach which is a web-based education system that performs individualized instruction

on the domain of programming languages is presented. This approach is fully implemented and evaluated

in an educational application module, called Fuzzy Knowledge and Preference Based E earning

(FuzKPBE). This also tracks the events and preferences of the users before finding the data. In particular,

FuzKPBE Performs user modeling by dynamically identifying and updating a student’s knowledge level of

all the concepts of the domain knowledge. The operation of FuzKPBE is based on Fuzzy clustering by

Local Approximation of MEmberships (FLAME ) that are used to represent the dependences among the

domain concepts. FuzKPBE uses fuzzy sets to represent a student’s knowledge level as a subset of the

domain knowledge. Thus, it combines fuzzy theory with the overlay model. Moreover, it employs a novel

inference mechanism that dynamically updates user stereotypes using fuzzy sets. It should be noted that the

overlay model and stereotypes constitute two widely used methods for user modeling.

Abstract- Nowadays, all the countries need to extend their industrial sector to a wider area. Whatever the

source as well as constructions are available, energy is necessary to give life for these industries. With the

advancement of technology, there is a lot of energy crisis. This crisis occurs due to transportation of power

supply, eddy current laws and their factors, etc.More power loss occurs due to power transmission. The

renewable energy resource gives a little support for electrical energy as a backbone to solve energy crisis.

It’s time to convert the renewable energy sources to hybrid energy sources which are nothing but the

combination of two or more renewable energy resources. This increases the efficiency of renewable energy

resources.

But there is still energy loss in renewable energy sources. Hence the solution for this only hybrid

technology which leads the way eco-friendly.

Index terms- Concept of hybrid technology, about energy crisis, present day use of renewable energy

Abstract: This paper proposes a new technique, based on the application of discrete wavelet transform

(DWT) for detecting high impedance faults (HIF) in the electrical power system networks. The phase

current waveforms during normal and fault conditions are decomposed using DWT which converts time

domain current signals into time-frequency domain current signals. The features extracted using DWT

during high impedance fault conditions and other power system disturbances helps to discriminate the high

impedance faults in the power system networks. The proposed technique is implemented in a simple MV

network and in a feeder network to discriminate high impedance faults from other faults. The results are

validated using Simpower System in MATLAB.

Abstract—At present scenario, renewable energy sources are needed to meet the energy demand. They also mitigate

environment pollution problems. The shortage of electrical energy demand can be meeting with renewable energy

resources. A wind turbine (WT) and photovoltaic (PV) solar panels are primary energy sources. Grid connected

renewable energy source like wind energy and solar energy are used to connect the hybrid system. Power electronics

converters are used as interfacing device between hybrid system (WT & PV) and the utility grid. These converters

are commonly based on a voltage source inverter (VSI) connected to the supply network. Grid side current control

PWM technique is applied to the voltage source inverter which reduces THD value to less than 1%. Power balancing

under heavy loaded conditions is also evaluated. The power factor correction is also determined. The simulation of

power balancing conditions, total harmonic distortion (THD) and power factor correction (PFC) are studied with

Multilevel Inverter Design with Anti Islanding Protection

S.Deepika1, B.Hemananth2, R.Hariharan3 1PG Student, Sri Eshwar College of Engineering, Coimbatore.

2,3Assistant Professor, Sri Eshwar College of Engineering, Coimbatore.

Abstract— Recently, photovoltaic (PV) power plants have attracted great attention, where medium-voltage grid

connection (typically 6–36 kV) is essential for efficient power transmission and distribution. A power frequency

transformer operating at 50 or 60 Hz will generally be used to step up the traditional inverter’s low output voltage

(usually ≤400 V) to the medium-voltage level. For the effective use of solar power generated, it should be connected

to grid. The modular multilevel cascaded (MMC) inverter topology is considered as a possible solution for grid

connection of inverters. Because of the heavy weight and large size of the power frequency transformer, the PV

inverter system is expensive and complex for installation and maintenance. As a different approach to achieve a

compact and light weight direct grid connection, this paper proposes a three phase PV inverter system with

transformerless concept. A common magnetic link is employed to interconnect PV arrays to grid. The elimination of

the line filter and step-up transformer from the traditional system will enable large cost savings in terms of the

installation, running and maintenance of the PV power plants. One problem with Distributed Generators (DG) is an

unwanted islanding phenomenon. This condition can be dangerous to grid workers who may not realize that the load

is still powered even though there is no power from the grid. This paper proposes a new active islanding detection

method based on impedance measurement which is a cost effective, simple, and effective method to prevent

islanding of grid-connected inverters.

ABSTRACT: In earlier days the excretory wastages of hens in the poultry farms was cleaned by employees. Due to

scientific and technological development, those wastages can be disposed by lot of cleaning vehicles. This cleaning

will be carried in the period of every month. But the wastes that are stockpiled over the layers of saw dust and sand

would get to be tightened and hence it needs to scrub every two days. By scrubbing the tightened thick layers into

spongy and squashed form, hygienic health for chickens can be maintained. But still today in India, scrubbing can be

done by employees only by means of manual work. This needs to include the labour cost also into the account of

poultry expenses. Cleaning the layers at every month and disposing those wastes is done by various high cost

equipments. To overcome these difficulties, a design in which the machine is to be automated for performing the

scrubbing operations, as well as cleaning and dispersing the wastes as manures to agricultural fields, with the help of

simple mechanisms and automata. Therefore the poultry waste management can be done.

Performance of an Implantable Electrical Coupled Loop Antenna inside Human Body V.Divyabharathi1,S.Kanmanroja2,B.Mythily3,G.Esaiyarasi4,M.Manikandan5

1,2,3,4,5 Dept of Electronics Communication, Vivekanandha College of Technology for Women

ABSTRACT: Implanted antennas are widely used in hyperthermia and biomedical applications. The antenna needs

to be extremely small while maintaining a permissible Specific Absorption Rate (SAR)and being able to cope with

the detuning effects due to the dielectric properties of human body tissues. Most of the proposed antennas for

implanted application are electrical field antennas such as Planner Inverted-F Antennas (PIFA) and micro-strip patch

antennas. By minimizing the size of an electrical field antenna, the near zone electrical field will increase, resulting

in higher SAR. This work is devoted to design a miniaturized magnetic field antenna to overcome the above

limitations. The proposed electrically coupled loop antenna (ECLA) has high magnetic field and low electric field in

the near zone and therefore, has a small SAR and is less sensitive to detuning effects. ECLA is designed at the

Medical Implanted Communication Service(MICS) bandwidth dimensions of (5*5*3mm3). ECLA has been

simulated inside one-layer human body model, three-layer spherical human head model, human headandhuman

body. From the simulation results, ECLA inside the human body has a 5 MHz{3 dB bandwidth, -14 dB gain, and

radiation efficiency of 0.525%. The 1g average SAR inside the human body for 10mW input power is about 1W/kg

which is 7 times lower than the SAR for a patch antenna of the same size with the same accepted power.

Abstract- The integration of small sized standalone solar systems to the grid is technically complicated resulting into expensive operation which is not affordable to all. This paper presents a smart controller which uses Digital

Signal Processing (DSP) for cost effective operation of solar-grid system. The hybrid system is capable of reducing

the size and deploys the operation strategy so as to effectively use the solar power. The synchronization is not necessary as this method can be effectively altered by the use of load discretization. This gives cheap, efficient,

reliable and cost effective operation. The system has been tested for the 120 Watt solar panel with the battery backup storage and its effectiveness is observed. The battery backup is made to operate during the cutoff of Grid or

Abstract- Indoor localization and monitoring system is a key factor in various emerging fields. Localization aware

computing has greater advantages in defence sectors. The technology is used all over in places where security

problems are a major issue. Localization and monitoring in a real time remote environment is a strenuous process.

Although there are several monitoring systems and approaches, issues and problem regarding their shortcomings

remains consistent. The most widely used system includes the use of a pyroelectric sensor. The pyroelectric sensory

system alone provides less accurate information of human localization and is restricted when there are multiple

targets. This system again posses limited accuracy. In this paper a fusion system module of both ultrasonic and

pyroelectric sensors are used. The system is experimentally demonstrated, this methods successfully tracked multiple

targets in a real-time environment. This fusion method possesses good accuracy and efficiency. With this accurate

localization mechanism for indoor environment, the provision of appropriate services for people can be realized,

ABSTRACT: Now-a-days ration card is mandatory for every home and is used in various fields such as family

member’s details, to get gas connection, for address proof and for various purposes. We use ration card to buy

various materials (sugar, rice, oil, kerosene, etc.) from the ration shops. But this system has two draw backs, first

one is that the weight of the material may be inaccurate due to human mistakes and secondly, if not buying the

materials at the end of the month, they will sell to others without any intimation to the government and the

concerned customers. This paper, proposes an Automatic Ration Materials Distribution Based on GSM (Global

System for Mobile) and RFID (Radio Frequency Identification) technology instead of ration cards. To get the

materials in ration shops, we need to show the RFID tag into the RFID reader, and then the controller checks the

customer codes and details of amount in the card. After verification, these systems will show the amount details.

Then the customer have to enter the required materials by using keyboard, after receiving information about the

materials the controller will send the information to government office and to the customer through GSM

technology. This system provides the materials automatically without the help of humans.

Abstract-Brain tumor classification is one of the major problems in diagnosing the tumor at early stage. Although

numerous tumor classification methods have been presented enhanced tumor classification is still challenging

because brain tumor MRI images exhibit high diversity in tumor appearance and boundaries. To address this

problem a novel brain tumor classification is proposed based on Neural Networks. Since misclassification occurs

due to high diversity in tumor boundaries. This method automatically classifies the tumor MRI images as benign,

grade1 grade 2 and malignant tumor. The classification of tumor is done mainly based on the knowledge of training

the network. Initially the network is trained with a set of MRI images using Back Propagation algorithm and later

they are tested with a testing image. This method mainly aims to improve the classification accuracy, reduce

computational time and to detect exact tumor location of low grade tumor. A classification accuracy of about 95% is

achieved using GLCM feature extraction technique and neural network.

[email protected] [email protected] Abstract —The increasing usage of media enabled handhelds and their integration with the in-vehicle entertainment systems,

resulted in the need for high data-rate services for mobile users on the go. This ever-increasing demand of data is constantly

surpassing what cellular networks can economically support. Large-scale Wireless LANs (WLANs) can provide such a service,

but they are expensive to deploy and maintain. Open WLAN access-points, on the other hand, need no new deployments, but can

offer only opportunistic services, lacking any performance guarantees. In contrast, a carefully planned sparse deployment of

roadside WiFi provides an economically scalable infrastructure with quality of service assurance to mobile users. In this paper, a

new metric called Contact Opportunity, to closely model the quality of data service that a mobile user might experience when

driving through the system is introduced. Then efficient deployment algorithms for minimizing the cost for ensuring a required

level of contact opportunity is presented. We further extend this concept and the deployment techniques to a more intuitive metric

– the average throughput – by taking various dynamic elements into account. Simulations over a real road network and

experimental results show that our approach achieves significantly better cost vs. throughput tradeoff in both the worst case and

average case compared with some commonly used deployment algorithms.

Abstract – In the color image processing methods, the image of dermatological ulcers are analyzed in order to detect the affected

area of the skin. The detection of classification rate focus on the application of feature extraction method that segment, classify

and analyze the tissue composition of skin lesions or ulcers. Indexing of skin ulcer images was performed based on the statistical

texture features derived from the RGB color components. This literature assesses the high level methology for dermatological

ulcer image classifier. The classifiers analyzed here are used for labeling the images by the dermatologist used in training and

testing of the classifier. The classification performance rate, coverage area of the affected skin is analyzed based on the choice of

different algorithms. Classifier uses the algorithm to perform attribute or feature selection that generates the candidate subsets of

attributes and evaluate them by using the training and testing schemes, thus creating the computed values of corrected classified

image rate up to 90% and assessed coverage area of affected skin up to 0.82.

Efficeient Routing In Mobile Ad Hoc Networks Using

Proactive Source Routing Protocol

Vallioor

Abstract—Opportunistic data forwarding has drawn much attention in the research community of multihop wireless net-working,

with most research conducted for stationary wireless networks. One of the reasons why opportunistic data forwarding has not

been widely utilized in mobile ad hoc networks (MANETs) is the lack of an efficient lightweight proactive routing scheme with

strong source routing capability. In this paper, we pro-pose a lightweight proactive source routing (PSR) protocol. PSR can

maintain more network topology information than distance vector (DV) routing to facilitate source routing, although it has much

smaller overhead than traditional DV-based protocols [e.g., destination-sequenced DV (DSDV)], link state (LS)-based routing

[e.g., optimized link state routing (OLSR)], and reactive source routing [e.g., dynamic source routing (DSR)]. Our tests using

computer simulation in Network Simulator 2 (ns-2) indicate that the overhead in PSR is only a fraction of the overhead of these

baseline protocols, and PSR yields similar or better data transportation performance than these baseline protocols. Index Terms—Differential update, mobile ad hoc networks (MANETs), opportunistic data forwarding, proactive routing, routing

Abstract — The explosive growth of high data rate in wireless networks has resulted in a tremendous increase in energy

consumption. Energy efficiency in wireless networks has drawn increasing attention of the research communities. High energy

consumption has a significant impact on the environment due to the associated CO2 emission. Moreover energy costs can account

for as much as half of a mobile service provider’s annual operating expenses. Energy consumption of a cellular network is

becoming important interms of both operational costs and environmental impacts. However, most existing works do not consider

the power grid, which provides electricity to mobile networks. Currently, the power grid is experiencing a significant shift from

the traditional grid to the smart grid. In the smart grid environment, only considering energy efficiency may not be sufficient

since the dynamics of the smart grid will have significant impacts on mobile networks. In this paper, green cognitive mobile

networks with small in the smart grid environment is studied. The problems of electricity price decision, energy-efficient power

allocation, and interference management is formulated as a three-stage Stackelberg game. The proposed stackelberg game is

analyzed using a backward induction method.

ABSTRACT - Sensor networks come in a wide variety of forms, covering different geographical areas,

being sparsely or densely deployed, using devices with a variety of energy constraints and implementing

an assortment of sensing applications. Congestion in Wireless Sensor Network (WSN) can cause missing

packets, low energy efficiency and long delay.Some applications need to transmit large volumes of data

concurrently from several sensors. These applications have different delay and QoS requirements.

Congestion problem is more urgent in such applications. To address this challenge, we propose a novel

which comprises three mechanisms:congestion detection using dual buffer thresholds and weighted buffer

difference ;Flexible Queue Scheduler for packets scheduling; Bottleneck-node-based source sending rate

control scheme. Simulations show that ECODA achieves efficient congestion control and flexible

weighted fairness for different class of traffic. Therefore it leads to higher energy efficiency and better

QoS in terms of throughput, fairness, and delay.

Abstract—Inpainting is the process used for filling the missing portion or a damaged part in an image. The missing portion can

be filled by using Examplar based inpainting which looks for the best matching patch with highest priority of the target region.

The image is first downsampled by a factor of 2 or 4. Then examplar based inpainting method is employed. The image quality is

improved by using super resolution algorithm which uses a loopy belief propagation performing a number of iterations of

upsampling. Three methods of inpainting, TM, NLM, NMF are performed. The performance of these three methods are evaluated

using three parameters PSNR, Mean Square Error and Histogram error.

Index Terms—examplar based inpainting, super resolution, loopy belief propagation, highest priority.

Abstract Reducing power plays a vital role in low power VLSI design. In the VLSI design circuits, clocking is the most

dominating power consuming element. To acquire the optimum power, it is essential to reduce the clocking power.

Hence this paper describes a method for reducing the power consumption by replacing some flip flops with fewer

multi-bit flip-flops. A combination table is used here to store the possible combination of flip-flops, for reducing the

search space and can be merged. This concept is implemented in a simple memory circuit. Our proposed work will

reduce the power by triple the time than that of the conventional system.

Abstract-- Face detection on general embedded devices is fundamentally different from the conventional approach on personal

computer or consumer digital camera due to the limited computation and power capacity. Numerous applications have been

proposed and investigated on embedded smart cameras, such as intelligent surveillance, human computer interface, person

authentication, human activity analysis, and so on. Among these applications, which are usually involved with humans, face

detection has played a fundamental and first-step role. The resource-limited characteristic gives rise to new challenges for

implementing a real-time video surveillance system with smart cameras. It also has several applications in areas such as content-

based image retrieval, video conferencing, video coding, intelligent human–computer interfaces and crowd surveillance. In this

work, we present the design and implementation of Rapid Real Time Face Detection, is a real-time face detection system

constructed on general embedded devices. It is a hierarchical approach to shift the complex computation to the promising regions.

It consists of five layers: skin detection, AIMD based contour point detection, region formation, filtering and modified V-J

detector. Processing time of this algorithm is low and produced a high detection rate. This framework also strikes a balance

between the detection speed and accuracy. We have implemented this algorithm on notebook, Android phone and our embedded

smart camera platform.

As the traffic load management is incredibly necessary for the task planning in wireless device networks, this paper

discusses a way to style a good routing rule for wireless device networks with traffic load unnatural.Firstly, internal

structure of a device node in wireless device networks is analyzed. Secondly, a way to style a good traffic load

unnatural routing rule for wireless device networks supported the hybrid multi-hop mode is mentioned. Within the

projected rule, the depth potential field and queue length field are outlined, so we tend to integrate them through

linear combination. Afterwards, we tend to utilize a structure that is created from real numbers to represent the

chromosomes, so succeed the traffic load unnatural routing call with supported the genetic rule. To avoid holdup,

the projected rule will distribute the focused traffic to the obtainable neighbor device nodes. Finally, simulations ar

conducted to form performance. Compared with different existing routing rule, the projected will effectively create

Abstract- In Manet the first demand is co-operative communication among nodes. The malicious nodes might cause

security issues like grey hole and cooperative attacks. To resolve these attack issue planning Dynamic supply

routing mechanism, that is referred as cooperative bait detection theme (CBDS) that integrate the advantage of each

proactive and reactive defence design. In region attacks, a node transmits a malicious broadcast informing that it's

the shortest path to the destination, with the goal of intercepting messages. During this case, a malicious node (so-

called region node) will attract all packets by victimisation solid Route Reply (RREP) packet to incorrectly claim

that “fake” shortest route to the destination then discard these packets while not forwarding them to the destination.

In grey hole attacks, the malicious node isn't abs initio recognized in and of itself since it turns malicious solely at a

later time, preventing a trust-based security resolution from detective work its presence within the network. It then

by selection discards/forwards the info packets once packets undergo it. During this we have a tendency to focus is

on detective work grey hole/collaborative region attacks employing a dynamic supply routing (DSR)-based routing

ABSTRACT - The most necessary issue that has to be solved in coming up with an information transmission rule

for wireless unplanned networks is a way to save unplanned node energy whereas meeting the wants of applications

users because the unplanned nodes are battery restricted. Whereas satisfying the energy saving demand, it’s

conjointly necessary to realize the standard of service. Just in case of emergency work, it's necessary to deliver the

information on time. Achieving quality of service in is additionally necessary. So as to realize this demand, Power-

efficient Energy-Aware routing protocol for wireless unplanned networks is planned that saves the energy by

expeditiously choosing the energy economical path within the routing method. When supply finds route to

destination, it calculates α for every route. The worth α is predicated on largest minimum residual energy of the trail

and hop count of the trail. If a route has higher α, then that path is chosen for routing the information. The worth of α

are higher, if the most important of minimum residual energy of the trail is higher and also the range of hop count is

lower. Once the trail is chosen, knowledge is transferred on the trail. So as to extend the energy potency any

transmission power of the nodes is additionally adjusted supported the situation of their neighbour. If the neighbours

of a node are closely placed thereto node, then transmission vary of the node is diminished. Thus it's enough for the

node to own the transmission power to achieve the neighbour at intervals that vary.

college of engineering,Coimbatore. Abstract: - The clock gating enables the clock signals from the CDN (clock distribution network). This technique

activates the clock which is needed for the operation of the circuit. The unnecessary clock signals are not activated

during the clock gating. This saves the dynamic power of the circuit. The auto gated flip-flops which are using

clock gating technique provides only small power consumption. The circuit based on look ahead clock gating is

used to avoid tight timing constraints for each clock pulses. The enabling clock pulses for the derived timing signals

to the gated logic saves the power from the flip-flops. The look ahead technique can also be used for reducing the

delay and the distortions from the circuit for the achievement of the application level. The novel approach we are

going to design is PBSCG (Partial bus specific clock gating) implemented in parallel counter for application level

implementation. This can be adopted for the all sectional view from particular architecture implementation. This

process could be available for the structural level implementation for all the CMOS logic gates for the integrated

ABSTRACT - Among the modern wireless networks, wireless sensor network plays a prominent role. Bunch

reduces the general energy consumption. In this paper HEF (High Energy First) bunch protocol is employed. This

protocol provides improved network time period since the energy level of the nodes are considered while choosing

the cluster head. The cluster area is fashioned dynamically and sporadically. The cluster heads are usually having

more resources (generally energy) on comparison with other nodes in the cluster. We tend to propose a globally trust

management theme that enhance security in WSNs. In this trust management scheme, trust model takes 2

methodologies, trust from direct observation methodology and trust from indirect observation method. In direct

observation methodology observer node gets trust value by exploiting theorem reasoning. On the other hand, with

indirect observation trust value is obtained from neighbor nodes of the observer node. The trust value for this

methodology is based on Dempster-Shafer theory. Combining these 2 trust models, we tend to get a lot of correct

trust values that results the effectiveness of our methodology

ABSTRACT - In Cooperative Communication, transmit multiple relay path design for multiple-input–multiple-

output (MIMO) decode-and-forward (DF) half-duplex two-hop relay channels with a direct source–destination link.

For the scenario where source and relay nodes are equipped with multiple antennas and the destination node is

deployed with single antenna, we formulate and solve the optimal beam forming vectors for source and relay nodes

jointly. The mobile users in each group amplify and forward their partner’s data stream using a frequency division

protocol. Based on the capacity contribution from the relaying terminal, a new parameter called cooperation

coefficient is introduced as a function of the relaying sub users. This parameter is used to modify the objective

parameter of the Fairness-oriented [Fading Channel] and throughput-oriented [Near End Channel] algorithms are

selected from the literature to test the proposed technique. Both algorithms are modified to employ the mean of

cooperation coefficient in the objective parameter of the subcarrier allocation procedure and shown to have a better

total throughput without any sacrifice. Using the mean of cooperation coefficient eliminates the need for the

feedback of the relaying channel to the base station. It is shown that by using the mean value of the cooperation

coefficient, instead of its instantaneous value, throughput of the system would still improve compared to the non-

cooperative case. Using the mean of cooperation coefficient leads to an implementable cooperative relay vectors for

some specific scenarios.

priority task. Slicing of interrupt timings is also discussed which can be used to improve the performance .the highest priority task is

serviced more number of times and with lesser time period. Hence it need not wait for the slack time of other previously higher

priority interrupts. If power will be less in grid, automatically power will be manage.

Abstract— In ad hoc network, the topology of network changes frequently due to the mobility of mobile nodes where the

communication is possible without any network infrastructure. Mobile nodes have limited energy resources so energy

efficient routing should be provided which increases the network life time. The existing routing mechanisms do not consider

ABSTRACT: In this paper, a novel three-port converter (TPC) with high-voltage gain for stand-alone renewable power system

applications is implemented. This converter uses only three switches to achieve the power flow controlling.the sources of two input

signal share the same inductor. Thus, the volume can be decreased.the conversion ratio of the converter is higher than other TPCs

technique. because of that, the degree of freedom of duty cycle is very long period of time. The converter can have a higher voltage

gain for both low-voltage ports with a lower turns ratio and a reasonable duty ratio slope. The voltage stress of switches is low; thus

conduction loss can be further improved by adopting low Rds (on) switches. so the high conversion ratio and high efficiency at the

same time in this converter can be acheived. The operation principles, steady-state analysis, converter's control method are

presented . A prototype of the proposed converter with a low input voltage 24 V for photovoltaic source, a secondary power port

voltage 48 V DC , and 400 V as output voltage is implemented to verify the theoretical analysis of the technique. The power flow

control of the converter is also built and tested with a digital signal processor.

ABSTRACT- This project aims at developing a dc-dc boost converter with high voltage step-up ratios. A novel high step-up

converter is proposed for a frontend photovoltaic system. Through a voltage multiplier module, an asymmetrical interleaved high

step-up converter obtains high step up gain. The voltage multiplier module is composed of a conventional boost converter and

coupled inductors. In boost converters, an LC-circuit with high quality factor (Q-factor) is employed to amplify the dc input voltage

to required high voltage level. For this, MOSFET power switch is employed to make and break a high current pulse through the

inductance. When current is made to flow through inductance, energy is stored in inductance and when this current is cut the stored

energy in inductance is transferred to capacitance, which results in a high voltage across capacitor and this high voltage is filtered

and fed to dc-bus.

ABSTRACT: This paper proposes a high-frequency high power density series load resonant inverter with an auxiliary switched

cell for induction heating appliances. The main objective is to achieve high power density by including a switched capacitor cell

with the capacitor-clamped half-bridge zero voltage switching high-frequency inverter circuit using the Pulse Density Modulation

control scheme. This control strategy allow inverter to work close to the resonance frequency for all output-power levels.At that

time , zero-voltage switching and zero-current switching conditions are performed and the switching losses are minimized. To

improve efficiency significantly in the low duty ranges, pulse density modulation (PDM) control can be used instead of PWM

because of the number of pulses control the output power. To highlight the proposed topology as a high-power-density inverter,

number of switches and output power have been taken into account as compared with regardless of efficiency. EMC filters are

added into the system which provides better output response. The problems related to existing systems like harmonics, noises,

flickers, high THD, reduced output power and failure of Zero Voltage Switching at low duty cycle can be minimised with the newly

designed topology.

ABSTRACT: The soft-switching ac link universal power converters have received noticeable attention during the

last few years. These converters, which can configured as dc–dc, dc–ac, or ac–ac, are compact, reliable and offer

longer life time compared to the other types of converters technique and also they require more switches, which

make the control process more diffcult. In the proposed a modified configuration for the dc–ac power conversion

process, which reduces the number of switches without changing the operating principles. This converter which is

named sparse ac-link buck–boost inverter reduces the number of switches from18 to 12. Despite reducing the

number of switches using in the proposed system, the partial resonant time, no power is transferred during that time,

is as short as the original configuration. special feature of this inverter is that it can be fabricated by MOSFET

modules which are more compact and more cost-effective compared to the discrete devices. the principles of this

proposed system is the operation of this configuration,the efficiency will be compared, the failure rate, current rating

of the switches in the proposed and original inverters.The failure rates of the sparse configuration are lower than the

original configuration so they have longer lifetime. The sparse configuration is slightly lower than that of the

original configuration of the efficiency. However by using reverse blocking MOSFETs in the sparse configuration,

the proposed inverter efficiency will be improved

Abstract- High Brightness Light Emitting Diodes (HBLEDs), however, have proven themselves to be a much better option. Like

incandescent bulbs, they reach full brightness immediately and do not contain any difficult to-dispose-of chemicals. They also

offer advantages over incandescents: they have incredibly long lifetimes and efficiency levels are continuously being increased. It

is being widely used in lighting applications, and therefore, their power supplies are required to have also high reliability and

efficiency. In general HBLED is performed without electrolytic capacitors, improving reliability but also increasing the low-

frequency ripple of the output voltage. This problem is solved using resonant converter is a perfect option for the second stage as

it has very high efficiency, it operates at constant switching frequency, and its output filter is small. But in the resonant converter

also more number of the switches is used which greatly increases the power consumption for AC-DC LED drivers ,this problems

is solved by using the diodes instead of switches in the AC-DC LED drivers. However, the standard configuration of the SD-SR

must be modified in this case in order to deal with the transformer voltage variations due to the input voltage ripple and, more

important, due to the LED dimming state. This modification is presented in this paper. Meeting this demand requires proper

testing and proper testing requires the proper test equipment. Experimental results with a 60-W prototype with an output voltage

of 12 V validate the proposed feed-forward technique and the proposed SD-SR circuit. No electrolytic capacitor is needed and the

efficiency in the resonant converter is as high as 94.5%.

ABSTRACT: This paper proposes a soft-switching which is not isolated two-way DC-DC convertor appropriate for

high increase and diminution applications. The planned convertor can do ZVS activate of all switches and ZCS put

off of some switches in each CCM boost and buck operations.An optimized switching strategy is given to attenuate

switch current rating and achieve soft-switching in wider vary. associate intermediate shift pattern is introduced to

hold out seamless mode amendment. Experimental results from a 5kW prototype unit are provided to validate the

planned conception. A typical application for this converter can be found in the auxiliary power supply of hybrid

electric vehicles. A two half-bridge circuit has been developed to implement the required power rating victimisation

by the minimum range of devices. Unified zero-voltage switching was achieved in either direction of power flow

with neither a voltage-clamping circuit nor additional. Switching devices and resonant elements. A two-way dc–dc

convertor is planned for the automotive engine/battery hybrid power generators. The two-stage two-way convertor

using a fixed-frequency series loaded resonant convertor is meant to be capable of operational beneath zero-current-

switching turn-on and turn-off not withstanding voltage and cargo variation, and thence its magnetic elements and

EMI filters is optimized. Also, a replacement autonomous and seamless two-way voltage control technique that

mixes 2 individual managementlers for low-tension aspect management and highvoltage side management by

introducing a variable current electric circuit is planned to supply uninterrupted power to vital ac masses and scale

back the scale of the dc bus capacitance and therefore the transition time. Also, a new autonomous and seamless

bidirectional voltage control method that combines two individual controllers for low-voltage side control and high

voltage side control by introducing a variable current limiter is proposed to provide uninterrupted power to critical

ac loads and reduce the size of the dc bus capacitor and the transition time.The proposed converter is a good

alternative to full-bridge isolated bidirectional dc–dc converter in medium-power applications.
