Abstract:

With an increase in agent applications has come an increasing need for agents to be able to interact with each other within open agent systems, such as the types of systems the Agent-Cities project is developing. These interactions are usually governed by protocols which dictate legal messages between agents for the course of that interaction. However, protocols can be rigid in the order in which messages can be sent, as well having a lack of robustness where even a small deviation will bring the protocol session to a premature end.

We have investigated how protocols implemented from the point of view of plans and goals would allow more flexibility and robustness than a strict message-order based mechanical protocol. We examine an attempt to translate a protocol to a set of plans and see if it adds any flexibility to using the protocol.

More flexible and robust protocols would allow autonomous agents to take advantage of their intelligence. By identifying problems when they occur whilst using a protocol they can intelligently resolve them, or even act proactively to avoid them.
