A methodology for making joint channel and routing assignments in multi-radio wireless mesh networks that takes into account interference constraints, the number of channels in a network and the number of radio available at each mesh router, and maximizes bandwidth allocation subject to fairness constraints. In particular, the methodology provides for routing, channel assignment and link scheduling in multi-radio mesh wireless networks utilizing a constant factor approximation technique that models the interference and fairness constraints and is able to account for the number of radios at each of the wireless nodes of a wireless mesh network.
