| 摘 要： | Ad Hoc无线网络环境下的多径路由是近来研究的热点之一.在DSDV路由协议的基础上,沿用传统路由协议中的最短路径准则,提出一种新的多径路由算法.算法通过建立一个多径路由表结构,实现多径扩展,并从理论上推导出特定仿真环境下路径的选择条数.最后分别对DSDV及其改进的多径路由协议进行仿真,结果表明多径路由算法以一定的路由开销为代价,有效地改善了网络的递交率及吞吐量性能.

| Abstract: | Recently, multipath routing is one of the key research problems in wireless Ad Hoc networks. In this paper, based on DSDV routing protocol, a novel multipath routing protocol is proposed using the shortest path criterion in the traditional routing protocol. And a multipath routing table structure is established to expand the multi-path mode, and the number of paths is theoretically calculated in the certain simulation scenario. Finally, the performance of the DSDV and the proposed protocol are simulated. The results show that delivery ratio and throughput of the net- works are improved in the protocol at the price of the limited routing load. |
