Cross Layer Multiserve Scheduling for Mobile WiMAX

Abstract

In Mobile WiMAX system, it is important to allocate resources appropriately for efficient application of resources among a variety of real-time and non-real-time services. We consider a cross-layer scheme for the downlink multiuser Orthogonal Frequency Division Multiple Access (OFDMA) for mobile WiMAX based on IEEE802.16e. We propose an intelligent Medium Access Control that adapts with physical layer in response to the different QoS requirements of the service flows in the system. Since Mobile WiMAX supports five kinds of services classes, it is important to gross QoS constraints of each class into consideration. Our scheme pleases the maximum delay requirements for real time service flows as well as minimum reserved data rate for non-real-time service flows sessions while maintaining a high resource utilization of the system.
