摘要
研究无线城域网PMP网络结构TDD模式下媒质接入机制和MAC层调度机制。通过对截断二进制指数算法的研究给出上行调度碰撞解决机制的一种实现方案,在保证QoS要求的同时最优地利用了动态分配的带宽。最后使用NS网络仿真软件对此进行了仿真,给出了UGS和rtPS调度业务数据仿真的结果。
This paper researches IEEE802.16d MAC layer protocol for a more detailed description and analysis of the PMP network medium access control performance and scheduling mechanism in TDD mode. A scheduling architecture is given after the analysis of truncated binary exponential back-off algorithm, and it can schedule uplink traffic to fulfill QoS requirements as well as make best use of bandwidth. This paper simulates the scheduling architecture by NS, and simulation results of UGS and rtPS services are given at the end.
