Multi-channel Multi-radio technology constitutes a viable approach to expand the capacity of Wireless Mesh Networks (WMNs). While many routing and channel assignment schemes have been proposed for WMNs, it is also important to integrate physical layer considerations into the routing process. In particular, multi-path fading is a challenging physical phenomenon, and it has been shown to be an important reason for packet loss in WMNs. In a multi-channel environment, the problem becomes more involved because different channels may undergo fading to varying extents. In addition, there exists significant interference owing to the power leakage between the channels used by adjacent Mesh Routers (MRs).
