The problem of coordination between distributed, autonomous agents in a tactical setting is considered. A coordination scheme based on the contract net formalism - whereby agents interact through execution of a protocol of contract (task) announcement, contract bid, and contract award - is investigated. To provide a context for evaluation of the scheme, a simulation testbed is used that abstracts features from the domain of electronic warfare and considers the problem of countermeasure deployment by a flight of aircraft against a complement of missile threats. The overall task of the team in this context is that of deciding which agent should employ a countermeasure against which threat. Preliminary evaluation of whether the contract net represents a viable coordination scheme in a tactical setting has been performed. Key parameters used in the evaluation include agent processing resources, both for internal processing and for interaction with other agents, as well as the resources available to execute tasks cooperatively. Results indicate that the contract net is able to improve team performance in tactical settings by effecting coordinated behavior, but that in order to realize this improvement a minimum increment in interaction resources is required.
