摘　　要：无人机自组网的高动态特性以及节点能量高度受限的特点,使得传统路由协议难以适用于无人机网络。针对该问题,在OLSR协议的基础上提出一种无人机网络适用路由(UAV-OLSR)算法。依据链路变化情况实现无人机集群状态感知,综合考虑节点能量、节点位置等因素进行节点质量评估。采用多径思想并通过特定的路径度量准则选择较优路径进行数据转发。仿真结果表明,与OLSR和AODV协议相比,UAV-OLSR具有更低的数据包平均传输延迟、更高的数据包投递率以及更好的能量均衡效果,可以延长无人机网络的生存时间。The Flying Ad-hoc Network(FANET)are highly dynamic,and the nodes are energy-limited,which makes it difficult for traditional routing protocols to adapt to UAV networks.In response to this problem,a routing algorithm,UAV-OLSR,for UAV networks is proposed based on the OLSR protocol.The algorithm realizes the status perception of UAV clusters based on link changes,and comprehensively considers node energy,node location and other factors to realize node quality assessment.In addition,the algorithm adopts the multi-path idea,selecting a data forwarding path that is optimal according to specific path measurement criteria.The simulation results show that UAV-OLSR has lower average packet transmission delay and higher packet delivery rate than OLSR and AODV.The proposed algorithm can extend the UAV networks lifetime.
