摘　　要：实现并维持网络覆盖是部署无人机网络的基本目的。然而,网络结构复杂,在无人机网络中实现并维持网络全覆盖是一项挑战工作。为此,对无人机网络覆盖性能进行研究,并利用逾渗理论推导实现覆盖的临界节点密度。对无人机在地面上的覆盖区域进行正六边形和正方形的近似处理,利用六边形棋盘和正方形棋盘对监测进行网格化,并结合逾渗理论,推导实现对监测区域进行全覆盖的临界节点密度。通过仿真实验,证实了所推导的临界节点密度的准确性。Realizing and maintaining network coverage is the basic purpose of deploying Unmanned Aerial Vehicular(UAV)Networks.However,the network architecture of UAV networks is intricate,thus,it is challenging to realize and maintain all the network coverage.Therefore,the coverage performance for UAV Networks is studied.The critical node density for realizing the coverage is derived by the percolation theory.The approximate treatment of network coverage of UAV on the ground is done with the hexagonal and square shapes.Then the hexagonal and square chessboards are used to make grid monitoring.The critical node density for all coverage of the monitored area is derived and realized with the percolation theory.Finally,the accuracy of the deduced critical node density is verified by simulation experiments.
