一种基于信息素图的无人机高效通信覆盖方法

Due to the high flexibility and good coverage capability of UAV, it is popular to choose multi-UAV for efficient communication coverage in practical applications. However, the requirements for the multi-UAV system with flexibility, low delay, long endurance and security need to be considered. To improve the continuous communication coverage capability of UAV, in the case of relatively sparse UAV, this paper proposes a method for UAV dynamic planning communication coverage, in which the pheromone map is employed and the turning radius of UAV is limited, so as to ensure flexibility, low delay and long endurance of the UAV. By introducing anchor nodes, the interaction model of pheromone guidance information is designed to ensure security of the UAV. Compared with the semi random heading method, the method proposed is much better than in terms of the maximum access time interval of the area to be covered, and can reduce the average access time interval by about 15%. Compared with the general pheromone map without geographical value description, the method proposed can reduce the average access time interval and the maximum access time interval of the method by about 6%. Through decoupling between UAVs, this method can avoid the asynchronous problem between UAVs.
