In this paper, the authors study the cross-layer optimization for TDMA-based wireless mesh backhaul networks under centralized control mode. Based on introducing a cross-layer optimization model whose optimal target is minimizing the system activation time, they enumerate all maximal concurrent transmission scenarios in wireless mesh backhaul networks by using the maximal cliques searching algorithm. Then the model of the optimization problem can be simplified and the computation speed of optimization can be improved dramatically. Furthermore, according to the flow character of the wireless backhaul network, they propose a fast heuristic algorithm based on classification of wireless link weight.
