Performance analysis of routing metrics for MultiRadio MultiChannel WMN

Abstract

Wireless Mesh Networks(WMNs) with multiradio multichannel capability have received much attention from research community. Routing in WMNs has been active area of research for many years. Routing metrics that have been proposed for WMN provide better path selection in comparision with hop count which is popular in wired networks. Expected Transmission Time (ETT) was proposed as better metric as compared to ETX so as to give weighting to throughput. Weighted Cumulative ETT(WCETT) allows accounting for concatenated links that interfere when using the same channel. Adhoc on demand distance vector (AODV) is a popular routing protocol design for MANETs which is also considered applicable as a routing protocol for WMNs. Further, an extension of AODV may support Multiple Radios and Multiple channels. In this paper we integrate WCETT and AODV to realize better routing for WMNs. We attempt to study and investigate performance of above said routing metrics using simulations from NS2 simulator. © 2012 Springer-Verlag.
