Introduction(1)
87% Of Connected Devices Sales By 2017 Will Be Tablets
And Smartphones. Mostly capable of connecting to the internet.
But….

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

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.”

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”

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.”

Proposed Solution

 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 Overview
Java 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.

Directory Facilitator
App Manager Agent
Agent Management System - provides the naming service; name,
ensure uniqueness, create/destroy agents
Directory Facilitator - provides a Yellow Pages service of which an
agent can find other agents providing the services it

Main Container listens and accepts incoming connections from other
containers and agents

Possibilities
 High-end Processing
 Image-Recognition
 Games
 n-queens problem
 sudoku solver
 Social Media Processing
 Video decoding
 Image file conversions
 Electronic Commerce
 User Authentication mechanism

Limitations and Future Work
 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
 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!
