摘　　要：弹道修正火箭弹多弹组成的无线网络由于节点高速运动、网络拓扑变化频繁,易导致弹节点间链路频繁断开,网络性能严重下降等问题。针对以上问题,提出了一种基于速度感知和路径稳定性的AODV路由改进算法RS-AODV。RS-AODV在路由发现阶段根据节点的位置和相对运动速度以及通信半径筛选出合适的路由节点,综合考虑节点剩余能量和路由跳数等因素,建立相应的路径稳定评估函数,通过路径稳定评估函数筛选出最佳路由线路方案。采用OPNET进行网络仿真表明,RS-AODV路由算法较经典的AODV更适合运用在高速运动的节点网络中。Due to the high-speed movement of the nodes and the frequent topology changes of the network, the trajectory correction rocket multi-missile network is easy to lead to frequent disconnection of the links between the nodes and serious degradation of network performance. To solve these problems, this paper proposed a speed-aware and road-stability AODV routing algorithm RS-AODV. In the routing discovery phase, RS-AODV selected some nodes with better routing performance according to the location and communication radius of nodes, and then considered the factors such as residual energy of nodes and the routing hops, thus established the corresponding path stability evaluation function. The best route scheme was selected through the path stability evaluation function. Conclusion is that, by using OPNET network simulation, RS-AODV routing algorithm is more suitable for high-speed mobile node network than classical AODV routing algorithm.
