This paper considers a heterogeneous team of cooperating unmanned aerial vehicles (UAVs) drawn from several distinct classes and engaged in a search and action mission over a spatially extended battlefield with targets of several types. During the mission, the UAVs seek to confirm and verifiably destroy suspected targets and discover, confirm, and(More)
— In this paper, we consider a heterogeneous team of UAVs drawn from several distinct classes and engaged in a search and destroy mission over a spatially extended battlefield with targets of several types. Some target locations are suspected a priori with a certain probability, while the rest need to be detected gradually through search. The tasks are(More)
— During the last few years several models of cooperative control among a team of agents have been proposed. In this paper, we study the impact of several system design parameters on a cooperative control methodology. An event-driven simulation model is developed to investigate how system design parameters affect the search and task performance of(More)
— Cooperative behavior in decentralized mobile agents requires communication among them. However, such communication can also have negative consequences for a variety of reasons, and the benefits of communication can vary over the course of the agent team's task or mission. In this paper, we compare the benefits of communication over time for a team of(More)
