摘　　要：转发UAV(R-UAV)的协助,能够将收集的视频数据传输至陆地上的节点,避免由收集视频数据的UAV(CD-UAV)直接向陆地节点传输视频数据。但存在传输数据的UAV数量越多,受干扰的UAV(I-UAV)数量就越多问题。为此,考虑到UAV电池储能容量的有限,提出基于传输功率控制和优化R-UAV位置的I-UAVs能效算法(TOEE)。TOEE策略一方面通过控制UAV的传输功率,抑制干扰,减少I-UAV的数量;另一方面通过优化R-UAV的位置,提高I-UAV的能效。仿真结果表明,功率控制和R-UAV位置的优化可以有效地提高I-UAVs的能效。With the help of relay UAV(R-UAV),video data collected by UAVs can be transmitted to ground node,thus avoiding the UAVs directly transmit their video data to ground node.However,as the number of transmitting UAVs increases,the number of UAVs affected by interference of other UAVs increases.Combined with limited energy storage capabilities of UAV batteries,the transmission power control and optimization of position of the relay UAV-based energy efficiency of disturbed UAV(TOEE)algorithm is proposed in this paper.TOEE algorithm controls the transmitted power of the UAV in order to suppress interference among UAVs.On the other hand,the energy utilization efficiency of the UAV can be further improved by optimizing the position of the R-UAV.Simulation results show that the power control and the optimization of R-UAV position can effectively improve the energy efficiency of disturbed UAVs.
