摘　　要：通过无人机平台搭载空中无线网络通信节点设备来构建空地网络可以克服地形条件束缚,提高全网沟通效率并拓展网络服务范围。而空中节点如何智能地、高效地完成任务动作是研究难点。以一个空中节点与若干个地面节点为研究模型,本文提出一种空中节点自主寻径策略:空中节点以自主方式在目标区域上空对多个可能的空中悬停点进行对比并从中选择最佳空中悬停点。研究与实验结果表明:该策略能够使空中节点自主完成空中悬停点选择,可快速实现对地面的网络通信覆盖;同时,该算法的计算复杂度不高,满足空中节点低能耗的任务要求。The restrict of terrain condition can be overcome, communication efficiency of the whole network can be increased and the range of the network service can be extended through taking advantage of sky network including wireless network communica- tion device or terminal carried by unmanned aerial platform, but how to intelligently and efficiently finish the task movement is a difficult issue. The study model including an aerial node and some land nodes is set up and an autonomic aerial node flight path choice is put forward： the multiple hovering points in the target area overhead can be autonomously compared and the optimal one can be selected. The research and test result shows that the optimal hovering point can be autonomously sdected in the flight path choice and the network communication coverage of the land network can be provided for a short while, moreover, the computing complexity of above algorithm is quite moderate and satisfies the low energy consumption demand.
