Unmanned aerial vehicle geographic position routing method based on link stability of communication security area

The invention provides an unmanned aerial vehicle geographic position routing method based on communication security area link stability, which aims at solving the problems of unstable communication edge and routing hole repair of a traditional GPSR routing protocol in an unmanned aerial vehicle ad hoc network application environment with frequent topology change and unstable communication link, and aims at solving the problems of communication edge stability and routing hole repair of the traditional GPSR routing protocol through setting a communication security area. And comprehensively measuring factors such as projection length of nodes in a communication security area, accumulated communication duration and flight direction of the nodes, and selecting a relay node with the most stable link to improve the link stability. In a peripheral forwarding stage, aiming at the problems of path redundancy and re-falling into a routing hole which are easy to occur in traditional peripheral forwarding, factors such a
