An Integrated Metrics Based Extended Dynamic Source Routing Protocol for Wireless Mesh Networks
Qiang Shen, Xuming Fang, Ying Shan · 2006
Wireless mesh networks (WMN) is a new distributed broadband access network. Compared with the typical mobile ad hoc network, it is with less mobility and usually not powered by the battery. Therefore, the traditional mobile ad hoc routing protocols are no longer suitable for WMN. In order to meet the performance requirements of multimedia traffic transmission, the routing protocol designed for WMN must take into account the load balance, fault tolerant and throughput, etc. This paper firstly introduces typical structures and characteristics of WMN, and several relevant WMN routing protocols. Then a method of integrated metrics based extended dynamic source routing (EDSR) protocol is proposed. The analysis and simulation results show that the proposed EDSR protocol improves the throughput of WMN significantly, which reaches the target of load balance simultaneously
