摘要: 给出了IEEE 802.16 PMP支持QoS的带宽调度算法,此算法由BS scheduler和SS scheduler共同实现,带宽的分配单位是时隙,并在NS-2上实现了该算法。通过建立仿真环境,对各种数据流的端到端的延时进行比较,结果表明算法的有效性。

Abstract: The scheduling algorithm supporting QoS in Point-to-MultiPoint(PMP) of IEEE 802.16 networks is given.It is based on BS scheduler and SS scheduler.Bandwidth allocation unit is slot in frame.Furthermore,the module is implemented in NS-2.The end-to-end delay of various flows is compared,and results of simulation show the effectiveness of the algorithm.
