This work presents a 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 analysing 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; and Markov decision process and linear programming techniques for optimal call admission control policy design. The book should be of interest to research scientists and graduate students working in the areas of wireless networks and QoS issues for multimedia traffic and related areas.

Due to the great success and enormous impact of IP networks, In­ ternet access (such as sending and receiving e-mails) and web brows­ ing have become the ruling paradigm for next generation wireless systems. On the other hand, great technological and commercial success of services and applications is being witnessed in mobile wire­ less communications with examples of cellular, pes voice telephony and wireless LANs. The service paradigm has thus shifted from the conventional voice service to seamlessly integrated high quality mul­ timedia transmission over broadband wireless mobile networks. The multimedia content may include data, voice, audio, image, video and so on. With availability of more powerful portable devices, such as PDA, portable computer and cellular phone, coupled with the easier access to the core network (using a mobile device), the number of mobile users and the demand for multimedia-based applications is increasing rapidly. As a result, there is an urgent need for a sys­ tem that supports heterogeneous multimedia services and provides seamless access to the desired resources via wireless connections. Therefore, the convergence of multimedia communication and wireless mobile networking technologies into the next generation wireless multimedia (WMM) networks with the vision of "anytime, anywhere, anyform" information system is the certain trend in the foreseeable future. However, successful combination of these two technologies presents many challenges such as available spectral bandwidth, energy efficiency, seamless end-to-end communication, robustness, security, etc.
