Introduction

Project Scope

• QoS of P2P network of wireless nodes

in the AODV routing

• Introducing noise to the network

– Movement and background traffic

• Inquiry Packet Interference

– Single node interference

– Multiple nodes interference

Qos : Quality of Service AODV : Ad-hoc On-Demand Distance Vector 3

Peer-to-Peer over Ad-hoc

network

Peer-to-Peer Architecture

• All nodes are both client and servers – Provide and consume

data

– Any node can initiate a connection

• No centralized data source – “The ultimate form of

democracy on the Internet”

– “The ultimate threat to copy-right protection on the Internet”

Cont.

Benefits • Efficient use of resources • Scalability:

– Consumers of resources also donate resources – Aggregate resources grow naturally with utilization

• Reliability – Replicas – Geographic distribution – No single point of failure

• Ease of administration – Nodes self organize – No need to deploy servers to satisfy demand – Built-in fault tolerance, replication, and load balancing

5

Ad-Hoc Network

• Collection of mobile wireless nodes forming a network without the aid of any infrastructure or centralized administration

• Nodes have limited transmission range

• Nodes act as a routers

6

Cont.

• Characteristics – Dynamic topologies

– Limited channel bandwidth

– Variable capacity links

– Energy-constrained operation

– Limited physical security

• Applications – Military battlefield networks

– Personal Area Networks (PAN)

– Disaster and rescue operation

– Peer to peer networks

Simulation

Scenario

To observe the effects of noise on

the Quality of Service over a mobile

network

3 different scenarios.

9

Scenario 1: Two Mobile Nodes

• Scenario 1 will serve as a reference for Scenario 2 and 3

shows in Figure 5. This simulation tests an Ad-hoc network

using the ADOV protocol.

10

Scenario 2: AODV Movement Baseline

• Scenario 2 involves 5 nodes; four nodes are positioned at same

distance away from each other and one node moves right to left

parallel to other four nodes and then once the node pass all four

nodes it moves up and away from the range of all the nodes.

11

Scenario 3

• This last simulation tests QoS of Ad-hoc network using

AODV protocol when the background traffic is

introduced. The specific types of data, constant bit rate,

and pack drop rate will be compared for analysing the

QoS of the network.

12

Simulation

Results

• Ongoing

• Currently analysing baseline

scenarios

• Focus will be on QoS between

expected trends and observed

trends

Future Works

• Adding Movement and background traffic – How the network behave and traffic changes

– Observe and analysis the changes in the traffic over the

network

• Multiple nodes interference testing – How does the Ad-hoc network changes
