A Mathematical Formulation for Joint Channel Assignment and Multicast Routing in Multi-Channel Multi-Radio Wireless Mesh Networks

Multicast routing is generally an efficient mechanism for delivering identical content to a group of receivers. Multicast is also deemed a key enabling service for a wealth of audio and video applications as well as data dissemination protocols over the last-mile backhaul Internet connectivity provided by Multi-Channel Multi-Radio Wireless Mesh Networks (MCMR WMNs). Major prior art multicast protocols in these networks center around heuristic or metaheuristic initiatives in which channel assignment and multicast routing are considered as two separate sub-problems to be solved in sequence. It might even be the cast that the solution for either of these two sub-problems is assumed to be pre-paratively calculated and given as input to the other.
