摘要
提出了一种新的Ad Hoc网络中对路由的维护方法,即基于局部多路径路由维护的路由软切换技术。在当前路由中某段或某几段链路出现问题时,通过建立局部的多路径路由,分担问题链路中的负载,维护网络保持通信连接不被中断;当路由稳定时,从局部多路径路由中寻找一条满足当前主路由通信需要的子路径,并且将数据传输切换到此子路径上,达到路由抢先维护和软切换的目的。该方法能够缩短路由重建的时间,延长单路径路由的寿命,使用多路径维护,避免了网络拥塞出现造成路由中断,能够很好地提高网络性能。
In this paper,we proposed a new method for maintain single path routing in mobile Ad Hoc network.This method is based on soft switch using partial muhipath routing. When the problem is appear in one link, the partial muhipath routing has been established to balance the load in error link .That can reduce the probability of link broken. Further,one link can be found to replace the error link to transmit data. This method can reduce the re-establish time of connections and prolong the lifetime of single path routing. Sequentially improve the network performance.
