> 中文摘要: 描述了一种基于多路径移动自组网络按需路由策略.在移动自组网络,由于网络节点的移动性及拓扑结构的易变性,路由成为最受关注的问题.在以前的移动自组网络路由算法中,主要采用的是传统的单路径方式.最近,多路径方式也逐渐出现,因为相对单路径路由而言,多路径为移动自组网络提供的QoS支持更可行、更高效.鉴于现有的移动自组网络多路径策略未能为源节点提供充分的信息,提出了一种新型的移动自组网络多路径路由算法.该算法可以将路由信息保存在源节点中,并依此在源节点中采用替换路径或多路径并发的方式进行数据传输.

Abstract:In this paper, a new scheme called aggregated multipath routing (AMR) is presented. In ad hoc networks, routing has been the most focused area for its nodes?mobility and topology variability. Now most of the on-demand routing protocols for current ad hoc networks build and rely on single route for each data session. It is proved in wireless networks that multipath routing is more effective and efficient than single path routing. So multipath routing protocols have been developed for ad hoc networks recently. Whereas these protocols have not provided a good scheme for the source node to collect enough information, a scheme called aggregated multipath routing is proposed. This scheme saves routing information in the source node, uses it to construct multipath, and sends data through these paths alternatively or simultaneously.
