Abstract: The problem of jointing routing and scheduling in TDMA based wireless mesh backhaul networks is studied. The objective is to maximize the spectrum efficiency. A novel routing algorithm is proposed, which jointly considers the traffic of nodes, the average capacity of paths, and the interference of links. Based on the correlation of the maximal clique at the bottleneck area, a novel link scheduling algorithm for the traffic pattern of Internet access is proposed. The joint optimization problem is solved by interactive feedback between two modules. Simulation results show that the proposed algorithms can significantly improve the system performance under various interference scenarios and save energy for effective communication.
