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.

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

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.

Agents Communication

FIPA ACL + Ontology

FIPA ACL Parameters & Performatives

Performatives Function

request To request an agent to another agent to perform some action.

inform The sender informs the receiver that a given proposition is true.

refuse One agent to state to another agent that it will not perform some action uses it.

confirm The sender informs the receiver that a given proposition is true, where the receiver is known to be uncertain about the proposition.

Parameter Functionalities

:sender Sender of the message

:receiver Intended recipient of the message

:content Content of the message

:in-reply-to Whether the sender expects a reply and if so, an identifier for the reply

Activity Main Window Activity Home Page of app.

LoginActivity User has to login to enter the app. It needs username and password. It is for security of user.

RequestActivity User can request friend to view friends location on app. MapViewActivity User can view the location of himself and his friends’ location. Also

user can know how many kilor meters far from he and his friend location.

InviteActiviy User can invite his friends on app. But user should know his friend email address.

ViewActivity User can view lists of his friends who are friends on app. User has authorization to remove their friends and also user can notify their friends’ location.

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.

SingUpAcitiviy 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.

LocationAgent 360 q  LocationAgent 360 is a free smartphone app based

on agent technology

JADE-LEAP+ Android SDK = Agent based application

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.

LocationAgent 360 q  We can know when our friends are on their way so that we

can know who are running late.

AIT 200 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.

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.

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.

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.

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.
