| 摘 要： | 在Ad Hoc网络中，如何基于多信道有效地利用网络中的频谱资源，提高网络的性能，已经成为近几年来研究的热点。在DSDV路由协议的基础上，提出了一种基于减少网络中的信道切换的路由算法——OLCH-DSDV，该算法采用最小切换时延的信道分配策略，尽量减少信道切换产生的时延，从而降低了网络时延，提高了吞吐量。该算法要求源节点通过自身维护的路由和信道使用信息，选择到达目的节点的最优路径，也就是需要最少信道切换的路径。仿真结果表明该路由改进算法在有效提高系统吞吐量的同时，也有效地减少了网络中的传输时延。

| Abstract: | How to improve the performance of the wireless Ad Hoc network by utilizing the spectrum resources efficiently based on multi-channel has become a hot research topic in recent years.In this paper,an On-Least Channel Handoff-DSDV(OLCH-DSDV) routing algorithm was proposed,which was based on the traditional DSDV protocol to reduce the channel handoff in the network.This algorithm used a channel allocation strategy with minimum channel handoff,so as to cut down the handoff delay.Thus it could reduce the average ... |
