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.
Keywords:IEEE 802.16  NS-2
