摘要

The IEEE 802.16(d) standard generally defines two operational modes: the Point-to-Multi-Point mode and the mesh mode. Because of mesh mode advantages over other wireless networks, flexible and low-cost deployment, Wireless Mesh Networks (WMNs) are becoming an important mode to the infrastructure based wireless networks, as a wireless backbone network. IEEE 802.16 MAC protocol uses TDMA. There are two types of scheduling algorithms: centralized and distributed. Although these standards specify how transmissions should occur, they do not discuss scheduling algorithms to find when transmissions should occur. Analytical and simulation results prove that there is a scalability problem in current standard algorithm which causes poor performance in dense network. In WMNs, holdoff algorithm in the bandwidth reservation procedure, affects the performance improvement directly. In this paper a new adaptive and static approach is proposed which can reduce contention efficiency and thus enhance throughput in dense networks. To survey performance of our purposed algorithm in contrast to standard algorithm several simulations are performed with various network payloads.
