uav cooperative control has been applied in many complex uav communication networks. It remains challenging to develop uav cooperative coverage and uav energy-efficient communication technology. In this paper, we investigate current works about uav coverage problem and propose a multi-uav coverage model based on energy-efficient communication. The proposed model is decomposed into two steps: coverage maximization and power control, both are proved to be exact potential games(EPG) and have Nash equilibrium(NE) points. Then the multi-uav energy-efficient coverage deployment algorithm based on spatial adaptive play(MUECD-SAP) is adopted to perform coverage maximization and power control, which guarantees optimal energy-efficient coverage deployment. Finally, simulation results show the effectiveness of our proposed approach, and confirm the reliability of proposed model.
