Abstract: 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 communication 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 selected 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.
