利用 ETX路由度量的无线Mesh网络协调机会路由协议
Coordinated opportunistic routing protocol with single-rate using ETX routing metric in WMN
摘要
Abstract
To solve the problem of lots of retransmissions and frequent execution of route discovery process in traditional routing protocols,this paper proposed coordinated opportunistic routing protocol based on ETX routing metric.Firstly,it exploited the broadcast nature of wireless networks to find the optimal routing solution that maximizesd throughput and minimizes packet loss. Then,it addressed the key issue of computational overhead by designing new routing technique.Finally,it used the source node sending credit and cost to calculation node domains and finish routing discovering.The simulation results show that the proposed protocol increases average throughput up to 32%,and increases in delivery ratio (from 10% to 20%)in various parameters. When compared to other novel protocols,the proposed protocol gets better performance in duplicate transmissions and network col-lisions.关键词
