摘　　要：无人机自组网路由协议OLSR(Optimized Link State Routing)在一些网络拓扑变化频繁的场景下,链路容易中断导致通信失败,数据包丢失,进而致使通信时延较高,影响网络性能。针对此问题,研究通过优化TC消息的数据包格式维护链路稳定性,以及将最短路径的路由算法进行改进,以提高数据传输成功率,进而降低总时延。仿真结果表明,相较于OLSR协议,改进协议提高了发包成功率,降低了端到端时延。Optimized Link State Routing(OLSR):In scenarios with frequent network topology changes,link interruption is easy to result in communication failure and packet loss,resulting in high communication delay and affecting network performance.To solve this problem,the link stability is maintained by optimizing the packet format of TCmessages,and the routing algorithmof the shortest path is improved to improve the success rate of data transmission and reduce the total delay.Simulation results show that compared with OLSR protocol,the improved protocol can improve the success rate of packet sending and reduce the end-to-end delay.
