Within the wireless mesh network, a bottleneck problem arises as the Number of Concurrent Traffic Flows (NCTFs) increases over a single common control channel, as it is for most conventional networks. To alleviate this problem, this paper proposes a Two-Stage Coordination Multi-radio Multi-channel MAC (TSC-M2MAC) protocol that designates all available channels as both control channels and data channels in a time division manner through a two-stage coordination. At the first stage, a load balancing breadth-first-search-based vertex coloring algorithm for multi-radio conflict graph is proposed to intelligently allocate multiple control channels.
