What is JADE?

• JADE - Java Agent DEvelopment Framework is a framework to develop and run multi-agent systems in compliance with the FIPA specifications.

– Developed by Telecom Italia @TILab

– Distributed under LGPL

Can be downloaded from http://jade.tilab.comFree registration is required

• The JADE bookDeveloping Multi-Agent Systems with JADEFabio Bellifemine, Giovanni Caire, Dominic GreenwoodEditor: WILEYISBN: 978-0-470-05747-6


Main features of JADE

• JADE is a middleware that facilitates the development of multi-agent systems. It includes

– A runtime environment where JADE agents can “live” and that must be active on a given host before one or more agents can be executed on that host.

– A library of classes that programmers have to/can use (directly or by specializing them) to develop their agents.

– A suite of graphical tools that allows administrating and monitoring the activity of running agents.


FIPA-compliance

• JADE complies with the FIPA standards

– FIPA = Foundation for Intelligent Physical Agents

– Its standards include:

• Agent communication (ACL)

• Agent management

• Agent message transport

• Abstract architecture

• Applications

JADE distributed architecture

Platforms

Containers


Containers and Platforms

• A JADE platform enables agents' execution. Platforms are composed of one or more containers

• A main container differs from normal containers as it holds two special agents (automatically started when the main container is launched).

• The AMS (Agent Management System) provides the naming service (i.e. ensures that each agent in the platform has a unique name) and represents the authority in the platform (for instance it is possible to create/kill agents on remote containers by requesting that to the AMS).

• The DF (Directory Facilitator) provides a Yellow Pages service by means of which an agent can find other agents providing the services he requires in order to achieve his goals.


Agent lifecycle

Agents are “born”, “live”, and eventually “die”


Installing JADE1) Download and install JAVA JDK

2) Go to http://jade.tilab.com/download.php

3) Register (create your user)

4) Login and download jadeAll.zip

5) Extract jadeAll.zip to a folder (e.g., c:\jade, /home/user/jade)

– We will refer that folder JADE_HOME from now on

6) Add the following files to CLASSPATH:

– .

– JADE_HOME/lib/http.jar

– JADE_HOME/lib/iiop.jar

– JADE_HOME/lib/jade.jar

– JADE_HOME/lib/jadeTools.jar

Windows:SET CLASSPATH=%CLASSPATH%; .; c:\jade\lib\http.jar; c:\jade\lib\iiop.jar; c:\jade\lib\jade.jar; c:\jade\lib\jadeTools.jar;


Installing JADE

Test your JADE installation: executejava jade.Boot -gui


Did it work?

JADE is running properly if this GUI is shown

JADE can runwithout GUI


The JADE GUI anatomy

Basic operations onagents:• Start• Kill• Suspend• Resume• Send Message• Migrate• Clone

Debugging/runtime tools:• Sniffer (“interaction spy”)• Dummy agent• Log Manager• Introspector (agents internals)• Add platform

Active agents


A simple exercise with the GUI

• TODO:

– Repeat the same exercise with two providers

– Run the sniffer to monitor what happens

Next classes

• We will cover the main topics of JADE

• Hands on!

– Exercises

– Discussion

• Project assignments

– Simulation of a real-life scenario as a multi-agent system

– You will receieve detailed specification

– Creativity is required to simulate at best

– 2-3 members per team

– We will give you hints and check the progress of your projects
