Providing quality of service (QoS) guarantees is an important objective in the design of the next-generation wireless networks. In this book, we address the QoS provisioning problem from both the network and the end system perspectives. In the first part of the book, we investigate the problem of statistical QoS provisioning from the network perspective. We propose and develop a link-layer channel model termed the effective capacity model. The effective capacity model captures the effect of channel fading on the queueing behavior of the link, using a computationally simple yet accurate model,...

High data-rate real-time applications such as streaming multimedia will be supported in the next generation wireless networks. Services required by these applications are different from traditional voice and file transfer services in that they expect both low transmission delay and high throughput. Providing quality of service (QoS) guarantees to those applications poses a big challenge for the design of wireless networks. This dissertation focuses on the power and resource allocation schemes for delay-constrained communications. The QoS requirement is statistically modeled by the triplet of...
