摘　　要：目前AdHoc网络(自组网)的路由研究正成为Adhoc网络发展的热点,在Adhoc网络中大多数按需路由协议使用单路径路由,但单路径容易断裂,往往需要重新路由。多路径路由在稳定性,均衡负载方面优于单路径路由,非常适合Adhoc网。该文通过理论分析得出多路径路由的稳定性与路由策略有密切的关系,从而提出了一种按需的独立多路径算法。该算法在DSR协议的基础上建立和使用一组完全独立的多路径进行路由。该文将算法与现有的一些算法进行了比较分析,模拟的结果显示独立多路径算法比SMR,DSR更有效。Now Ad Hoc Networks is becoming the main interest in Internet.Most proposed on-demand routing protocols build and rely on single path.However for the dynamic topology of Ad hoc networks the single path is easy broken and need perform a route discovery process again.In Ad hoc networks Multipath routing is better suited than single path in the stability and load balance.This paper first analyzes the stability of the multipath and gets that the stability of multipath routing is closely related to the routing strategies,so it proposes an independent multipath routing scheme which is based on DSR and utilizes a group of independent paths to route.This paper compares the algorithm with some protocols (SMR,DSR),the simulation result shows that the algorithm is more effective than SMR,DSR.
