Summary

This work presents a thorough review of the state-of-the-art techniques for maintaining QoS support for multimedia services over wireless networks. Several novel ideas and algorithms on integrated connection- and packet-level QoS, dynamic radio resource management, and multimedia QoS-aware services are described. Special emphasis is given to the following: -Mathematical models for analyzing connection-level and packet-level QoS, -Radio resource management schemes for TDMA and CDMA systems, -QoS-aware call admission control and seamless handoff schemes, -Dynamic call admission control for CBR and VBR traffic, -Markov decision process and linear programming techniques for optimal call admission control policy design. Radio Resource Management for Multimedia QoS Support in Wireless Networks will be of great interest to research scientists and graduate students working in the areas of wireless networks and QoS issues for multimedia traffic and related areas.
