An Efficient QoS-Aware Resource Allocation Scheme in WiMAX

Abstract

In this paper, we propose a QoS-aware resource allocation scheme for IEEE 802.16d fixed WiMAX system operating in TDD mode. It focuses on the performance enhancement of the resource allocation. The proposed scheduling algorithm flexibly adjusts bandwidth among the different traffics to try to get the best efficiency while considering the fairness among the different traffics in a way. The efficiency of the proposed QoS-aware resource allocation scheme is revealed through simulation.
