摘要： 研究了IEEE802.16在mesh模式下的带宽调度策略,提出了分层调度模型.以调度开销最小为原则得出链式拓扑存在最优调度分界,证明了可以分解成链式拓扑集合的任意mesh网络调度也存在最优分层.给出了mesh最优分层的解,并分析了BS覆盖范围对分层的影响.数值仿真结果显示了分层带宽调度明显降低了调度需要的开销和跳数.

Abstract: This paper studies strategy of bandwidth schedule in the IEEE 802.16 based on the mesh mode and proposes a stratified scheduling model.According to the principle of schedule load minimization, we conclude that an optimum division in the schedule exists in chain topology and prove that any mesh network, which can be decomposed into an aggregate of chain topology, also has the optimum stratification.A solution to the optimum stratification is provided, and the effects of BS's cover area on the stratification analyzed.Numerical results show that the bandwidth schedule with stratification remarkably decreases the loads and hops needed by scheduling.

Key words: IEEE 802.16, mesh, bandwidth schedule
