Comparative Study of Routing Protocols for WMN

Today, Wireless Mesh Networks has been recognized as a new attractive communication paradigm due to their ease of deployment and ability of fault tolerance. WMN is a multi-hop wireless network which builds high performance infrastructure and provides efficient communication using various Routing Protocols. Traditional routing protocols like AODV, DSR and DSDV etc. support Ad-hoc networking in which devices doesn't have capability to provide fault tolerance. To overcome this, several types of Opportunistic based routing protocols have been proposed i.e. EXOR and SOAR etc. which support combination of both Ad-hoc and Mesh networking. All these protocols like EXOR and SOAR exploit the broadcast nature and provide the capability of fault tolerance using multiple alternate paths and redundant copies of data packets. Further, we have shown the comparative performance analysis of EXOR and SOAR using various network parameters i.e. network throughput, robustness (against node/link failure), hop count, bandwidth consumption and traffic congestion for multiple different nodes network.
