ABSTRACT
Scheduling is a critical component of worldwide interoperability of microwave access (WiMAX) that impacts significantly on its performance. Scheduling schemes help in providing service guarantees to heterogenous classes of traffic where there are a variety of different quality-of-service (QoS) requirements. In addition to scheduling, bandwidth requests, admission control, and bandwidth allocation mechanisms also play crucial roles in QoS provisioning for WiMAX. In general, a scheduler for WiMAX needs to be simple, efficient, fair, scalable, and have low computational complexity. It should also be able to protect against misbehaving flows and provide decoupling and necessary bounds on throughput and delay performance. The mesh and point-to-multi-point (PMP) modes of WiMAX require different scheduling architectures.
