Adaptive Call Admission Control for QoS Provisioning in WiMAX

The need to support ubiquitous connectivity with higher data rate for mobile computers and communication devices are fuelling a growing interest in broadband wireless access (BWA) networks. WiMAX(Worldwide Interoperability for Microwave Access ), a technology based on IEEE 802.16 is a standard for Wireless Metropolitan Area Networks (Wireless MAN) which aims to provide broadband access in the "last mile" with QoS (Quality of Service) guarantees for heterogeneous class of services with different QoS requirements. The QoS requirements are given in terms of bandwidth, latency, jitter, reliability etc. Although IEEE 802.16 standard defined the QoS parameters, they do not specify how these QoS parameters are satisfied and it is an open issue for research. This book analyses the design of Adaptive Call Admission Control (CAC) scheme for QoS provisioning in IEEE 802.16 based WiMAX networks. This book will be helpful to post graduate students and especially to those who want to continue research in call admission control aspect of WiMAX networks and other cellular based networks.
