摘　　要：改进自组织按需平面距离向量(ad hoc on-demand distance vector,AODV)路由协议,以缓解其在无人机自组网中链路易断裂和修复效率低且开销大的问题。以路由开销最小、平均邻居节点数最大和节点间链路失效时间最长为优化标准建立链路,以保证链路的稳定性。从断裂处寻找上下游节点能量最强的共同邻居节点,分别建立其与断裂处上下游节点之间的链路,以提高修复速度,并避免断裂位置约束。当无人机节点速度为100m/s时,改进协议节点剩余能量增加54.4%,端到端的时延可降低21%,路由发现频率降低53%,丢包率降低17.2%。The ad hoc on-demand distance vector(AODV) routing protocol is improved to alleviate the problems of easy link breakage,low repair efficiency and high repair cost in unmanned aerial vehicle(UAV) ad hoc networks.Taking the minimum routing overhead,the maximum average neighbor nodes number and the longest inter-node link failure time as the optimization criteria,the link is established to ensure its stability.If a link break occurs,it only needs to identify and introduce the most powerful common neighbor node to the upside and downside of the fault,and reestablishe the link.It can improve the repair speed and avoid the constraint of fracture location.By the improved routing protocol,as the UAV nodes move at a speed of 100 m/s,their residual energy can be increased by 54.4%,while,the end-to-end delay can be reduced by 21%,the frequency of route discovery by 53%,and the packet loss rate by 17.2%.
