Abstract :
This paper investigates the effectiveness of dynamic resource allocation scheme in WiMAX (Worldwide Interoperability for Microwave Access) system following to the WiMAX standard. Simulation experiments are performed for the case of MAC PDU (Media Access Control packet data unit) without fragmentation and numerically expanded for the fragmentation case. We used a technique called Dynamic Burst Mapping (DyPBM) to allocate the resources to mobile users, and this is then compared to other non-dynamic resource allocation techniques. Numerical study shows that the dynamic technique (DyPBM) achieves the highest goodput increment of up to 0.7 Mbps when the MAC PDUs are fragmented. Nevertheless, dynamic technique is less effective in the case of without MAC PDU fragmentation since it achieves low channel utilisation over the other non-dynamic techniques. This is because the available slots in some frames are insufficient to support the big PDU sizes as these PDUs (Packet Data Units) are not split into small fragments. This study thus concludes that the dynamic resource allocation is only significant when PDU fragmentation is applied in the WiMAX networks; nevertheless, there is a trade-off in terms of the complexity.
