摘　　要：针对小型无人机自组网节点数量多、位置动态变化、续航时间有限等特点,对经典航空路由协议(The Aeronautical Routing Protocol,AeroRP)中的判据进行改进,设计了一种基于节点生存时间的路由判据,综合考虑网络内无人机节点的剩余飞行时间、当前矢量速度、相关节点间距离和单跳最大传输距离等参数,通过对上述参数的无纲化处理得到判距,进而选取最优的下一跳节点。利用ns-3网络软件对改进判据进行仿真实现和性能分析,结果表明,新的路由判据在AeroRP中应用后,网络的传输吞吐量、准确度和时延等指标都明显好于经典的主动式路由协议——优化链路状态路由协议(Optimized Link State Routing Protocol,OLSR);并且相比经典AeroRP协议中的判据,改进判据在数据传输准确度提高的前提下,当网内节点数量超过70个时网络数据传输的吞吐量明显提升,更适合节点数量较多的应用场合。In consideration of the characteristics of small Unmanned Aeronautical Ad Hoc Network(UAANET),such as large number of nodes,dynamic location changes and limited survival time,the metric in classical Aeronautical Routing Protocol(AeroRP)is improved and a routing metric based on node survival time is proposed.The proposed routing metric takes into account the remaining flight time,current vector speed,distance between related nodes and maximum single-hop transmission distance of UAV nodes in the network.The optimal next-hop node is selected by the distance judgement based on the non-dimensional treatment of the above parameters.The simulation implementation and performance analysis based on ns-3 network software shows that,the transmission throughput,accuracy and delay of the network are significantly better than those of the classic active routing protocol——Optimized Link State Routing Protocol(OLSR);under the condition that the accuracy of data transmission is improved,the network data transmission increases significantly based on the proposed routing metric compared with the routing metric in the classical AeroRP protocol when the number of nodes in the network exceeds 70.The proposed routing metric is more suitable for the application with a large number of nodes.
