摘要
主要分析了Ad Hoc网络中单径路由协议和多径路由协议的特点。从路由中断时所传输分组的丢失率角度考虑,提出了一种单径路由和多径路由的路由协议选择算法。该算法考虑了由于网络的动态拓扑导致链路频繁失效时,原有路由中各节点缓存的分组会被丢弃的特征,通过选择合适的路由协议,降低分组的丢失概率,提高网络效率。
From the view of the loss rate of transmitted packets while route breakage occurring, an algorithm of routing protocol selection between single-path protocol and multi-path protocol is presented. In Ad Hoc network, the existing route may become unusable frequently due to the dynamic topology of Ad Hoc network. In this case, the packets in the nodes of the disabled route will be rejected. The routing selection algorithm can choose proper routing protocols to reduce the packet loss rate and increase the efficiency of the network.
