The IEEE 802.16 mesh network, which is self-organized and self-configured with multi-hop, is deployed to providing an effective solution for broadband wireless access system. The standard defines the basic scheduling scheme, but doesn’t specify the resource allocation and routing scheme in the protocol. Therefore, designing a reasonable scheduling and routing algorithm to enhance the capability is very important for the system. In this paper, we propose an efficient and practical routing algorithm which takes the channel condition and modulation mode into consideration in an IEEE 802.16 mesh network. Furthermore, our algorithm enables direct communications between subscriber stations without referring to the base station. Simulation results show that our algorithm effectively improved the scheduling length, delay and system throughput.
