摘　　要：随着作战样式的变化和武器装备的变革,装甲车辆机动突击作战中协同控制的重要性不断增强,对网络通信的各项性能指标提出了更高要求,而自组织网络所具备的一些优良特性能够较好地适应这一需求。在网络通信中,稳定性是衡量网络路由性能的重要因素。机动突击作战中,车辆移动、障碍物阻挡等因素将导致网络拓扑变化迅速,给路由稳定性带来严重影响,极大地降低了网络通信质量。基于AODV协议,设计并仿真了一种链路不相交的多路径被动式路由协议,以路由回复消息中携带的路由信息为基础,实现两条不相交链路作为通信路由并互为备份。仿真结果表明,该协议在数据包到达率及平均时延方面较AODV协议均有一定提高。Due to the variety of combat mode and the innovation of weapon equipment, cooperative control of armored vehicles in mobile assault becomes more and more important. Therefore, network with high performance is required. In virtue of some excellent features, Ad-hoc network can well satisfy this requirement. In network communications, stability is one of the most important indicators of network routing performance. However, in mobile assault, factors such as fast movement and obstacle will cause rapid variation of network topology and bad impact on the network stability. Consequently, it brings bad debasement to the communication quality. In this paper, an on-demand routing protocol based on disjoint multi-path is analyzed and simulated. Routing information carried by route-reply messages is used to choose two disjoint links which are the backup of each other. This protocol is the improvement of AODV（Ad-hoc 0n-demand Distance Vector） mechanism. The simulation results show that the presented protocol can achieve lower packet-loss-rate and shorter end-to-end delay.
