Wireless mesh network have the potential to deliver internet broads and access, resource sharing wireless local area network coverage and network connectivity for stationary or mobile hosts at low cost both for network and customers. In multi radio multi-channel wireless mesh networks, many approaches have been developed to maximize the network throughput with limited channel resources. It is understood that limited spectrum resources can be fully exploited by utilizing partially overlapping channels in addition to non overlapping channels in 802.11b/g networks. In this work, an extension to the traditional conflict graph model i.e., weighted conflict graph is proposed to model the interference between wireless links more accurately. We present a novel optimal channel assignment algorithm which has the potential to obtain better solutions. Through simulations, we demonstrate that the network performance can be dramatically improved by properly utilizing the partially overlapping channels. The qos performance of the proposed channel assignment algorithm is compared with existing methods.
