    Abstract: Supporting quality of service (QoS) guarantees for diverse
    multimedia services are the primary concerns for WiMAX
    (IEEE 802.16) networks. A scheduling scheme that satisfies QoS
    requirements has become more important for wireless communications.
    We propose a downlink scheduling scheme called adaptive
    priority-based downlink scheduling (APDS) for providing QoS
    guarantees in IEEE 802.16 networks. APDS comprises two major
    components: Priority assignment and resource allocation. Different
    service-type connections primarily depend on their QoS
    requirements to adjust priority assignments and dispatch bandwidth
    resources dynamically. We consider both starvation avoidance
    and resource management. Simulation results show that our
    APDS methodology outperforms the representative scheduling approaches
    in QoS satisfaction and maintains fairness in starvation
    prevention.
