Abstract

In this chapter, we present a multiagent system architecture for dynamic coalition formation and coalition strategy learning in a realtime multisensor target tracking environment. Agents operate autonomously, and they have incomplete information about their potential collaborators. In addition, accurate target tracking requires that multiple agents recognize and synchronize their actions-collecting measurements on the same target within the same time frame. Therefore some form of cooperation is necessary. In our system, agents form coalitions via multiple 1-to-l negotiations. However, due to the noisy and uncertain properties of the environment, coalitions formed can be only suboptimal and satisficing. To better adapt to changing requirements and environment dynamics, each agent is capable of multiple levels of learning. Each learns about how to negotiate better (case-based learning) and how to form a coalition better (reinforcement learning). To increase the chance of reaching a high-quality negotiated deal, our work also addresses issues in task allocation and dynamic utility-based profiling.
