Quality of Service (QoS) differentiation in WiMAX networks is a critically important part of QoS support that has not been properly addressed in the literature. Radio Resource Management (RRM) techniques such as packet scheduling and admission control have been studied by many research groups, and although they claim to provide QoS differentiation in their schemes, no studies have truly evaluated and measured the QoS differentiations among various service classes. In this study, we propose quantifying QoS differentiation using a new parameter called Fairness, which could measure QoS differentiation among various service classes. By simulation results, we show that Fairness values could provide detailed information about QoS differentiation, where throughput and delay fall short of comparison analysis for QoS support among Real Time (RT) versus Non-RT (NRT) applications.
