Multi-UAV cooperative task assignment is broadly applied in many fields and thus widely studied.However,the application scenarios of communication constraints and resource consumption allocation methods are often ignored.Therefore,this paper proposes a distributed multi-UAV task assignment method based on CNP to solve the above problems.This method can be divided into four steps,that is,task release,bid application,coalition formation and contract signing.In the task release stage,the adaptive setting method of maximum number of information transfer times is proposed to limit the range of recipients and reduce communication load.In the process of coalition formation,the resource consumption allocation algorithm based on the Gini coefficient is proposed to reasonably adjust the resource difference between UAVs in the coalition.The simulation results prove the effectiveness of multi-UAV task assignment method based on CNP and resource consumption allocation algorithm based on the Gini coefficient.
