Ad Hoc网络中基于能量综合权值的EIW-DSR路由算法

针对Ad Hoc网络中DSR路由算法没有考虑能量消耗而造成的网络"热点"问题,本文提出一种基于能量综合权值的路由算法—EIW-DSR。该算法利用权值综合了路径节点上的能量消耗、剩余能量及其方差、枢纽性等参数,具有能耗低、负载均衡、可靠性强等优点。仿真结果表明,与DSR路由算法和WBDSR路由算法相比,该算法在节省能量消耗、均衡负载、消除网络"热点"、延长网络生命周期方面均得到了较大提高。

An EIW-DSR Route Algorithm Based on the Energy Integrated Weight in Ad Hoc Networks

The DSR route algorithm always has the “hot spot” problem for failing to consider energy consumption in the Ad Hoc networks. In this paper,we propose a novel routing algorithm EIW DSR(Energy Integrated Weighted DSR). It  integrates the node energy consumption,residual energy and energy variance,and the node hub of the path. Furthermore,EIW DSR has some characteristics such as low energy consumption,load balanced,and high reliability and so on. Simulation results showed that,the EIW DSR has made an improvement at the saving energy,load balance,and eliminating “hot spot”. Moreover,the networks’ life prolonged extensively comparing with DSR and WBDSR route algorithm.
