چکیده (انگلیسی):

This paper proposes a utility-based scheduling framework for
efficient differentiation of users’ Quality-of-Service (QoS) in a broadband
wireless access system involving heterogeneous mixed traffic flows. The
utility-based scheduling framework, called Maximum QoS Satisfaction
(MQS), is based on three novel Radio Resource Allocation (RRA)
techniques; delay-based scheduling policy for Real-Time (RT), minimumrate-
based scheduling policy for Non-Real-Time (NRT) and a throughputbased
scheduling policy for Best-Effort (BE) services. Simulation study
shows that MQS achieves superior performances in terms of average
system throughput and user satisfaction both in single and heterogeneous
mixed traffic scenarios, when compared to some existing ones.
