Title

Resource Management In Wimax Networks

Abstract

In this chapter, we investigate resource management mechanisms in Worldwide Interoperability for Microwave Access (WiMAX) networks, including subcarrier assignment, adaptive power allocation, and call admission control schemes. Subcarrier assignment scheme deals with how to allocate subcarriers to form a subchannel. Adaptive power allocation allows the transmitter to grant different power levels to different subcarriers according to the channel state information. Call admission control highlights how to distribute a subscriber's access bandwidth over different types of applications such that the quality-of-service (QoS) requirement of each connection is guaranteed. We focus on orthogonal frequency division multiple access (OFDMA) with time division duplex (TDD) environment, which allows high-spectrum utility effciency on the uplink and downlink channels in asymmetric "last-mile" Internet access. We conclude this chapter with an optimization strategy that finds a balance between the revenue of a WiMAX service provider and the satisfaction of WiMAX subscribers.
