Propose Mobile Agents aided Offloading framework for data,

applications, processes and/or services from a mobile device

(android) to a cloud environment

Definitions

Offloading -sending heavy computation to a resourceful remote location

and receiving the results back.

JADE(Leap) – Java Agent DEvelopment (Light Extension Agent

Platform)

Mobile Agents - software abstraction that can migrate across the

network representing users. They communicate using

agent communication language (acl) realize a set of tasks

and goals it was designed for

Cloud Environment - remote servers and software networks that allow

centralized data storage and online access to computer

resources

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Problem Analysis – Security(1)CloneCloud – “security is assumed basing on the trusted virtual

machines, all the device data is replicated in the cloud to ensure

synchronous virtualization

between the device

and its clone.”

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Problem Analysis – Security(2)ThinkAir – “it assumes a trustworthy cloud server execution

environment: there is hope that

whenever data is offloaded to the

cloud, the code and state of the

data are not maliciously

modified or stolen”

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Problem Analysis – Interoperability

MAUI – “it is more dependent on the hardware architecture of the hosts.

Mobile devices typically have different CPU instruction architecture

than desktops and servers. Processes cannot be easily run on devices

with different architectures.”

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Proposed Solution

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Mobile agents encapsulate data, instructions and protocols.

Ability to move transparently across different hosts.

Capable of adaptive learning and automation.

Some intelligent agents are equipped with techniques to check self-

integrity.

JADE OverviewJava based platform for running mobile agents which supports an

asynchronous agent programming model and Communication(using

ACL) between agents either on the same or different platforms.

Limitations and Future Work

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

JADE still limited to android devices

Offload decisions need an algorithmic approach(i.e. when and when

not to offload).

I am currently working on an image recognition project with the aim

of developing a framework for other android developers to use to

offload tasks.

Conclusion

IEEE, ICCPCT-2015, International Conference on Circuits, Power and Computing Technologies

Offloading is an important feature in enhancing android mobile

capabilities.

JADE provide migration of bundled code and state to remote locations.

JADE agent mobility help achieve distributed processing without

taking much attention on the underlying operating system of each

platform.

Thank You!
