摘　　要：为提高移动自组织网络(mobile ad hoc network,MANET)路由查询效率,通过对P2P(peer-to-peer)网络与MANET的交叉研究,在DSR协议基础上引入Chord算法,提出双向路由模型BPDSR.BPDSR双向路由发现算法和路由资源共享算法,降低了查询复杂度,减少了路由失效和绕路问题.通过BPDSR算法性能分析和NS--2仿真实验表明,BPDSR路由模型的路由效率明显提高.To improve the inquiring efficiency of MANET route,this paper expanded Chord algorithm into DSR and presented a routing model BPDSR through the study of P2 Pand MANET.By bi-directional routing algorithm and shared routing algorithm,BPDSR lowered the inquiring complexity and eliminated the invalidity of route and detour problem.Put the new protocol into simulation in NS-2and compared its performance with DSR,The results show that the inquiring efficiency of BPDSR is better.
