This paper proposes a scheduling scheme for wireless mesh networks that are capable of multiple channel access and equipped with multiple radio interfaces. The proposed scheme is interference and traffic aware in that it increases the overall achievable throughput of the network by eliminating the interference between the wireless mesh routers and maximizes the satisfaction ratios of all active sessions by accounting for the sessions' data rate requirements. Simulation results show that the proposed scheme outperforms the Tabu-based scheduling scheme and yields good tradeoffs between the achievable throughput of the network and the satisfaction ratios of the sessions.
