摘要
在移动Ad hoc网络中,节点的移动通常会导致通信链路的断开。为降低断路对通信质量的影响,保存备用路由是有效的方案之一。但维护备用路由同时也增加了其控制信息开销,占用一定的带宽并消耗有限的能源。分析了几种路由备份的方式,以仿真比较其控制信息开销,并给出其适用范围。
In mobile Ad hoc network,the mobility of nodes often leads to link＇s failure. To alleviate the effect on communication quality caused by link failure, one of the effective methods is to maintain backup routes. But route maintenance will increase the control message cost, which will take up some bandwidth and consume the node＇s limited energy. Some route maintenance mechanisms are analyzed, and made a comparison by simulation,finally gaven out their scope of application.
