Protocols
The following examples show how to use the support provided JADE to implement interaction protocols.
FIPARequestInitiatorAgent | |
Description: | |
This example shows how to implement the initiator role in
a FIPA-request interaction protocol. In this case in particular
we use an AchieveREInitiator ("Achieve Rational effect")
to request a dummy action to a number of agents (whose local
names must be specified as arguments).
This example should be used together with the FIPARequestResponderAgent as described below. Start the JADE runtime (with the management GUI) and launch some FIPARequestResponderAgent on it. java jade.Boot -gui r1:examples.protocols.FIPARequestResponderAgent r2:examples.protocols.FIPARequestResponderAgent Then, from another window (or from the management GUI), launch an FIPARequestInitiatorAgent specifying the local names of the responder as arguments. java jade.Boot -container i:examples.protocols.FIPARequestInitiatorAgent(r1 r2) |

FIPARequestResponderAgent | |
Description: | |
This example shows how to implement the responder role in
a FIPA-request interaction protocol. In this case in particular
we use an AchieveREResponder ("Achieve Rational effect")
to serve requests to perform actions from other agents. We use a
random generator to simulate request refusals and action execution
failures.
This example should be used together with the FIPARequestInitiatorAgent as described here. |

ContractNetInitiatorAgent | |
Description: | |
This example shows how to implement the initiator role in
a FIPA-contract-net interaction protocol. In this case in particular
we use a ContractNetInitiator
to assign a dummy task to the agent that provides the best offer
among a set of agents (whose local
names must be specified as arguments).
This example should be used together with the ContractNetResponderAgent as described below. Start the JADE runtime (with the management GUI) and launch some ContractNetResponderAgent on it. java jade.Boot -gui r1:examples.protocols.ContractNetResponderAgent r2:examples.protocols.ContractNetResponderAgent Then, from another window (or from the management GUI), launch an ContractNetInitiatorAgent specifying the local names of the responder as arguments. java jade.Boot -container i:examples.protocols.ContractNetInitiatorAgent(r1 r2) |

ContractNetResponderAgent | |
Description: | |
This example shows how to implement the responder role in
a FIPA-contract-net interaction protocol. In this case in particular
we use a ContractNetResponder
to participate into a negotiation where an initiator needs to assign
a task to an agent among a set of candidates.
This example should be used together with the ContractNetInitiatorAgent as described here. |

BrokerAgent | |
Description: | |
This example shows how to implement nested protocols.
In this case in particular we want to implement a broker agent
that forwards incoming requests to perform actions to another
agent. To implement that we use an AchieveREResponder ("Achieve Rational effect")
and we register an AchieveREInitiator in the state where the
requested action has to be performed.
This example should be used together with the FIPARequestInitiatorAgent and the FIPARequestResponderAgent as described below. Start the JADE runtime (with the management GUI) and launch one FIPARequestResponderAgent and one BrokerAgent on it. Specify the name of the responder as an argument to the broker. java jade.Boot -gui r:examples.protocols.FIPARequestResponderAgent b:examples.protocols.BrokerAgent(r) Then, from another window (or from the management GUI), launch a FIPARequestInitiatorAgent specifying the local name of the broker as argument. java jade.Boot -container i:examples.protocols.FIPARequestInitiatorAgent(b) |
