Abstract

The efficient scheduling is crucial to QoS (quality of service) provisioning for multimedia flows. In this paper, we study on the scheduling algorithms for mobile WiMAX (worldwide interoperability for microwave access) based on IEEE 802.16e. Considering the states of queues, the channel conditions and the QoS requirements of service classes, we propose a cross-layer designed scheduling algorithm called DMIA (dynamic MCS and interference aware scheduling algorithm) for the uplink of WiMAX. Our algorithm can dynamically adapt the varying modulation and coding scheme (MCS) and the interferences in wireless channel. The simulations for the IEEE 802.16 system indicate that the proposed algorithm provides efficient QoS scheduling without starving the connections at low priority.
