摘要:

提出了一种新的Ad hoc网络多路由协议算法——源宿双备份多路由协议算法.该算法改进了on-demand multipath routing for mobile Ad hoc networks(ODMR)多路由协议,在保存中间节点到目的节点备份路由的同时,也保存源节点到中间节点的备份路由,有效地延长了路由生存时间,从而减少了寻路和RREQ泛洪次数,降低了网络时延.仿真结果表明,源宿双备份路由协议的性能比ODMR协议有较大提高.

关键词: Ad hoc 网络, 路由协议, 多路由

Abstract:

A new multipath routing algorithm called double backup multi-path routing, based on on-demand multipath routing for mobile Ad hoc networks (ODMR), is proposed, which preserves not only the routings from intermediate nodes to the destination, but the routings from the source to the intermediate nodes. It performs much better than ODMR, prolongs the lifetime of a routing, and reduces the frequency of request floods and time delay as shown by the simulation results.

Key words: Ad hoc, route protocol, multipath
