摘要
为提高移动自组织网络(mobile ad hoc network,MANET)路由协议效率并增强其网络可扩展性,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,提出基于网络物理拓扑的分级路由模型LPDSR。采用按需建环机制和分级路由算法,降低查询复杂度,减少绕路问题。LPDSR算法性能分析和NS-2仿真结果表明,该路由模型的网络可扩展性明显提高。
To improve the routing efficiency and enhance the network scalability of the MANET, the Chord algorithm was expanded into the DSR and a layered routing model LPDSR was presented based on the physical network topology. By structuring on demand and adopting layered routing algorithm, the LPDSR lowered the inquiring complexity and eliminated the detour prob- lem. The new protocol was put into the simulation in NS-2 and its performance was analyzed. The results show that the sca- lability of the LPDSR is better.
