3. Introduction
q Location based mobile application using multi agent
based approach.
q Using JADE-LEAP, software framework, is a part of
the multi agent system to develop mobile application.
q On Android OS using Android SDK
q For agent communication, using FIPA ACL and
Ontology
q Integration with Google Play services such as Google
map.

4. Objectives
To develop a proof of concept location based social
tracking multi agent system application.
q To develop and implement agent based Android mobile
application using JADE LEAP to be a part of multi agent
system.
q To design a multi agent platform and development
framework for building mobile application across Android
operating system.
q To design agent messages format and ontologies using
FIPA ACL

5. Problem Statements
q Most of the mobile applications are based on client-
server architecture with server doing all of the hard
work and backend data storage.This has heavy privacy
implications with our private data being stored on the
servers.
q Typical mobile application are controlled by server.To
provide users’ dynamic needs better, multi agent
systems is the best approach to develop mobile
application.
q Most of the location sharing mobile applications do
not work together each others because they do not
support the any open standard for data.

FrienddetailActivity
User can see not only the friends lists but also the detail of friends
information. In the same way, User can set notification of their
friends and can remove their friends.
SharelocationActivity
User can share their location.
SigninActivity
User are already member of app. User need to sign in only using his
email address and password to enter the app.

If user are new user for this app. User has to sing up first as user of
app.
LogoutActivity
User can logout after using the app.

on agent technology
JADE-LEAP+ Android SDK = Agent based application

36. LocationAgent 360
q To keep families and close friends connected stay in sync
throughout their busy day.
q We can see where our family and friends are on a private
map, stay in touch with group get help in an emergency.

37. LocationAgent 360
q We can know when our friends are on their way so that we
can know who are running late.
AIT200 m
q We can notify our location and our friend location so that we
can know easily what time our friend arrive home and leave
from home.
q Using LocationAgent360 is not only sharing location each
other but also save for emergency case and time consuming.

40. Discussion
q JADE platform supports efficient and transparent messaging
over different platforms (JavaSE, JavaME, .NET,ANDROID).
q It supports semantic rich communication via implementation
of FIPA ACL specifications for performatives, protocols and
ontologies.The use of ontologies in communication messages
allows extension of application features.
q JADE multiagent platform has Peer-to-Peer abilities and like
others P2P system. It needs some coordinator agents (eg. DF,
AMS ).
q There is no dependence on proprietary commercial services
like GoogleHangoutService.

41. Limitation
q Need Google(Gmail) account and have to register as
Google developer to use officially Google service and
Google map
q To check all of the validity emails , we can use Oauth or
OpenID, open standards for all email servers.
q Limited features implementation.
q Currently only implemented on Android OS.

42. Conclusion
q Develop and implement agent message format and
ontologies to be used in LocationAgent 360.
q This application enables location based distributed multi-
agent systems in which personal agents running on mobile
deices can communicate with other agents to share
location without the need for a centralized server
orchestrating every interaction.
q The application design merges multiagent-based JADE-LEAP
platform with latest Android Application Code and Google
Play API (for location detection and map services).
q It is a good proof of concept and a starting point to develop
more sophisticated applications based on mobile user
agents that learn about user preferences and negotiate with
other agents to offer more services in different
environments, different agents and their respective
behaviors.

43. Recommendation Future Work
q Implement and develop agent based mobile application run
on different operation system such as Window, Symbian OS
and even MIDP enable feature phones (eg. Nokia Asha
phones).
q The ontology designed in this research is limited to location
sharing and notification features with some social abilities.
Ontology can be extended to further support more use
cases and add features by integrating with all other available
data and information.
