Abstract: When the heterogeneous multi-UAVs are performing the missions of cooperative reconnaissance and attack, there exists the problem of local task allocation under the constraints of communication distance and time delay. In this paper, a distributed multi-UAV task allocation method is proposed based on the contract net protocol. First, an optimization model of the local task allocation when heterogeneous multi-UAVs discover a new target is established. An information consensus algorithm is designed for the local UAV communication network to solve the conflict in the task announcement process. Then, a coalition formation and resource management method are proposed, so that the UAVs in the coalition can consume the resources in a more balanced way. Simulation results show that the proposed method can effectively solve the problem of task allocation of heterogeneous multi-UAV reconnaissance and attack mission under communication constraints, and can obtain the maximum system utility.
