With the advance of wireless technologies, wireless mesh backhaul networks (WMBNs) are emerging an alternative to conventional wired backbones for metropolitan areas. As real-time applications (e.g., voice over IP and video streaming) rapidly grow, provisioning quality-of-service (QoS) guarantees is one of the most important issues for WMBNs. In this paper the QoS problem for routing and scheduling in TDMA-based WMBNs was considered. An integrated routing and scheduling mechanism was proposed to provides QoS guarantees to real-time services with unrestricted topologies for TDMA-based WMBNs. A linear programming optimization is devised to solve the amount of non-collision bandwidth for a path according to the available resource and the interference. A simulation model is developed to investigate the performance of the proposed mechanism. Through the developed simulation, a series of experiments are conducted to show the capabilities of the proposed mechanism.
