Simulation Research on a New Scheduling Algorithm in IEEE802.16 MAC Layer

IEEE802.16, as a wireless MAN broadband access standard, defines a flexible QoS mechanism in MAC layer for wild variety classes of services. However, it dose not define specific admission control strategy and scheduling algorithm, which are becoming the research hotspot in recent years. In this paper, we focus on the features of services defined in IEEE802.16, including UGS, ertPS, rtPS, nrtPS and BE, and develop a new scheduling algorithm adapting these services. Finally, we validate the performance of the algorithm through a simulation experiment on NS2 platform.
