JADE Java Agent DEvelopment Framework g 913838 曾文駒 1

Introduction n JADE is a software framework fully implemented in Java language. n simplifies the implementation of multi-agent systems through a middle-ware that claims to comply with the FIPA specifications. n is free software (under LGPL) and is distributed by TILAB. n 2

Agent n n n A computational process that implements the autonomous, communicating functionality of an application. All agent communication is performed through message passing, where FIPA ACL is the language to represent messages. All agent have an Agent Identifier (AID). 3

FIPA ACL Message Parameters Parameter Category of Parameters performative Type of communicative acts sender receiver Participant in communication reply-to content Content of message language encoding Description of Content ontology protocol conversation-id reply-with Control of conversation in-reply-to reply-by 5

ACL Message in JADE GUI 6

Message Transport Protocol (MTP) n Three possible message transport protocol: Internet Inter-ORB Protocol (IIOP) n Wireless Application Protocol (WAP) n Hyper. Text Transmission Protocol (HTTP) n 7

Agent Platform (AP) n n An AP provides the physical infrastructure in which agents can be deployed. An AP consists of the machine(s), operating system, agent support software, FIPA agent management components (DF, AMS and MTS) and agents. 8

Agent Platform (cont. ) n n The agent platform can be distributed on several hosts. Only one Java application, and therefore only one Java Virtual Machine (JVM), is executed on each host. 9

Integration with JESS n JADE offers also a so-called Jess. Behaviour that allows full integration with JESS JADE provides the shell of the agent and guarantees the FIPA compliance n JESS is the engine of the agent that performs all the necessary reasoning n 18

Simple App. ─ Thanks. Agent n When Born registers with the DF n creates two child agents n each of this new agents registers with the DF n n If n n the father agent sends a message of greeting to the child agent Then it waits for an answer to the greeting n it thanks the agents that have answered n 19
