Wireless Quality of Service

This volume systematically addresses the QoS issues found in many types of popular wireless networks, including LANs, PANs, MANs, 3G, mobile ad hoc, sensor, and heterogeneous. It introduces the fundamental concepts of QoS provisioning and presents various techniques, such as a Markov chain model and a distributed admission control mechanism, to combat QoS problems that include performance impairments in WLAN hotspots, video streaming applications, and broadband wireless access. The book covers the standards of different wireless networks and the QoS service frameworks specified in the standards, along with recent research progress on improving the performance of QoS services in wireless networks.

Focusing on an important and complicated topic in wireless network design, Wireless Quality of Service: Techniques, Standards, and Applications systematically addresses the quality-of-service (QoS) issues found in many types of popular wireless networks.

In each chapter, the book presents numerous QoS challenges encountered in real-world applications and delineates ways to overcome these obstacles. Some of the challenges explored are performance impairments in WLAN hotspots, video streaming applications, and broadband wireless access. The techniques and mechanisms covered to tackle these problems include medium access and call admission control techniques, a parameter tuning algorithm, the QoS-enabling features of IEEE 802.11e, a Markov chain model, a probe-based distributed admission control mechanism, topology-transparent scheduling protocols, and a novel multicast congestion control mechanism.

Addressing advanced topics and future directions, the expert contributors acknowledge the need for more research to solve several open issues. In the meantime, they offer innovative solutions to solve current QoS problems.
