摘　　要：为了提高无线资源的利用率,基于802.16d协议的MAC层资源调度模型,提出了一种最优竞争接入调度策略,推导了最优竞争窗口的计算式,分析并实现了最优竞争接入调度策略。MATLAB数值分析和OPNET仿真结果表明:无限增大竞争窗口大小并不能改善接入性能,采用本最优竞争接入调度策略,可以得到最大平均接入用户数,实现资源优化。In order to improve the efficiency of wireless resources, this paper presented a new optimal contention based media access strategy for IEEE 802.16d based wireless network. It derived the optimal contention window according to the number of users, and formulated the optimal contention based media access strategy. The numerical analysis in MATLAB and simulations in OPNET show that the maximal mean number of access users are obtained and the resource can be optimized, while the performance will not be improved by increasing the window size continually.
