摘　　要：在无人机自组网(Flying AdHoc Networks, FANET)中,节点移速高,网络拓扑变化频繁。传统无线自组网按需平面距离向量路由协议(AdHoc On-Demand Distance Vector Routing, AODV)以最小跳数为准则,易引发广播风暴,导致路由控制开销上升、网络性能降低。为降低FANET节点的移速对网络性能的影响,将FANET节点间的相对移速和节点能耗作为评价链路稳定的因子,选择更稳定有效的FANET节点作为路由中间节点,提高链路存活率。使用OMNET++进行路由协议仿真,结果表明提出的算法能够有效提高网络性能,适应于高动态FANET环境。In FANET,the speed of mobile nodes and the network topology changes frequently.The traditional AODV protocol takes the minimum number of hops as the criterion,which may cause a broadcast storm and lead to the increase of routing control overhead and the degradation of network performance.In order to reduce the impact of the speed of FANET nodes on network performance,this paper takes the relative speed of FANET nodes and energy consumption of nodes as factors for evaluating link stability,and selects more stable and effective FANET nodes as intermediate routes to improve the link survival rate.Using OMNET++to simulate routing protocols,the results show that the algorithm proposed in this thesis improves network performance and can adapt to high dynamic FANET environment.
