Abstract

WiMAX is one of the most interesting solutions for broadband wireless access, offering QoS features for multimedia traffics and applications. However, without the definition of a mandatory scheduling algorithm for the assignment of channel resources, WiMAX standard is open to enhancements by QoS research groups and developers. In this paper, BS uplink scheduling algorithms are considered and an innovative solution is proposed in order to improve multi-rate fairness and QoS management. The proposed scheduler, named E-DRR, has been compared with the existing solutions through exhaustive simulations, showing its enhancements in terms of QoS performance and multi-rate fairness in resource allocation.
