摘　　要：路由协议对于无人机自组织网络(FANET)的服务质量(QoS)具有重要意义。FANET中节点的高速移动会带来网络拓扑剧烈变化,这一特性会加剧链路中断,从而导致网络QoS显著降低。本文提出一种基于链路质量的低路由开销协议(LQLR_LSR),针对FANET中多点中继(MPR)集进行优化,减少冗余的MPR节点,并修改基于期望传输计数(ETX),使其作为路由度量,融合正向传输成功率、反向传输成功率、链路分组大小和链路带宽4个特征,实现路由多径自适应。通过OPNET仿真结果表明,FANET环境下LQLR_LSR在平均吞吐量、发包成功率、路由开销和平均端到端时延性能方面明显优于Global_P_LSR和OLSR。The routing protocol is of great significance to the quality of service(QoS)of the unmanned aerial vehicle self-organizing network(FANET).The high-speed movement of nodes in FANET will bring about drastic changes in the network topology.This feature will aggravate the link interruption,resulting in a significant reduction in network QoS.This paper proposes a low routing overhead protocol based on link quality(LQLR_OLSR).It optimizes the multipoint relay(MPR)set in FANET to reduce redundant MPR nodes.Then modified the expected transmission count(ETX)based on it as a routing metric,integrated four characteristics of forward transmission success rate,reverse transmission success rate,link packet size and link bandwidth to realize routing multipath adaptation.The OPNET simulation results show that LQLR_OLSR in FANET environment is significantly better than Global_OP_OLSR and OLSR in terms of average throughput,packet transmission success rate,routing overhead and average end-to-end delay performance.
