Abstract :
This paper proposes the so-called adaptive resource scheduling (ARS) schemes to cope with both uplink and downlink traffic transmissions in WiMAX, in order to fully utilize the radio resource, and meet the various QoS requirements as well. Specifically, for the uplink transmission, each SS control and adjust its local sessions in a distributed manner; while for downlink the BS performs the resource scheduling in a centralized manner. The corresponding rate control mechanism is given, by adopting the control theory method as well. The simulation results also validate the efficiency and practice of our proposed scheme.
