In this paper, we address the topology control issue for future wireless mesh networks (WMNs) based on the principle of service-oriented design. In particular, we propose a novel topology control scheme that attempts to maximize the overall throughput in the network and that takes into account the traffic pattern. The main idea of the scheme is to establish multiple semi-permanent wireless highways, each of which can convey the traffic for nodes along the highway. To evaluate the performance of the proposed scheme, we conduct theoretical analysis, which demonstrate that viable solutions for highways do exist with high probability. The theoretical analysis also proves the optimality. Within the new topology control framework, we demonstrate that advance technologies, including network coding and physical-layer network coding (PLNC), can be applied to substantially improve the throughput capacity and confidentiality of the communications.
