Nodes moving with high speed can bring rapid topology change in tactical communication network,which may invoke new route discovery processes and lead to network performance degradation.To alleviate this problem,a novel Stable Wrapped Multi-path Routing (SWMR) protocol is proposed,which uses source routing approach to establish node-disjoint primary routes,and builds up several backup paths among each primary route synchronously by utilizing overheard route reply packets.By constructing such multi-path routes,the protocol not only provides higher network stability,but also reduces route discovery latency and routing overheads.Simulation results show that:compared with AOMDV and AODV,SWMR has a better routing performance in packet delivery ratio,average delay and normalized load metrics when the network topology changes rapidly.
