Integrated Downlink Resource Management for Multiservice WiMAX Networks

Overview This paper proposes a novel downlink resource management framework for multiservice WiMAX (Worldwide Interoperability for Microwave Access) networks. This framework consists of two major components: Adaptive Power Allocation (APA) and Call Admission Control (CAC). Each of them is formulated as an optimization problem, where the demands of both WiMAX service providers and subscribers are taken into account. To solve the optimization problems, the authors develop a fairness-constrained greedy revenue algorithm for downlink APA optimization and a utility-constrained greedy approximation algorithm for downlink CAC optimization. This simulation results show that, when combining the APA and CAC optimization methods together, the proposed resource management framework can meet the expectations of both service providers and subscribers.
