The purpose of this book is to provide tools for a better understanding of the fundamental tradeo?s and interdependencies in wireless networks, with the goal of designing resource allocation strategies that exploit these int- dependencies to achieve signi?cant performance gains. Two facts prompted us to write it: First, future wireless applications will require a fundamental understanding of the design principles and control mechanisms in wireless networks. Second, the complexity of the network problems simply precludes the use of engineering common sense alone to identify good solutions, and so mathematics becomes the key avenue to cope with central technical problems in the design of wireless networks. In this book, two ?elds of mathematics play a central role: Perron-Frobenius theory for non-negative matrices and optimization theory. This book is a revised and expanded version of the research monograph “Resource Allocation in Wireless Networks” that was published as Lecture Notes in Computer Sciences (LNCS 4000) in 2006. Although the general structure has remained unchanged to a large extent, the book contains - merous additional results and more detailed discussion. For instance, there is a more extensive treatment of general nonnegative matrices and interf- ence functions that are described by an axiomatic model. Additional material on max-min fairness, proportional fairness, utility-based power control with QoS (quality of service) support and stochastic power control has been added.

This book shows how networking research and quality engineering can be combined to successfully manage the transmission quality when speech and video telephony is delivered in heterogeneous wireless networks. Nomadic use of services requires intelligent management of ongoing transmission, and to make the best of available resources many fundamental trade-offs must be considered. Network coverage versus throughput and reliability of a connection is one key aspect, efficiency versus robustness of signal compression is another. However, to successfully manage services, user-perceived Quality of Experience (QoE) in heterogeneous networks must be known, and the perception of quality changes must be understood. These issues are addressed in this book, in particular focusing on the perception of quality changes due to switching between diverse networks, speech and video codecs, and encoding bit rates during active calls.

QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in. It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis. This same model is then applied to a wireless environment examining which elements are required to be able to deliver multimedia services across 2nd and 3rd generation mobile networks, detailing the components of data networking that will assist in guaranteeing service level performance and the constraints placed on those guarantees when passing services over an air interface to a wireless-enabled device. It asks a simple question: will multimedia applications and the guaranteed levels of service required by them work when traversing from fixed to wireless networks? It tracks QoS components and mechanisms of both environments and looks at what will provide the glue in this brave new converged world and also provides empirical data to back up the conclusions drawn. First book available which applies QoS techniques and technologies to wireless/mobile networks 3G/UMTS Deals with the search for the real time information that constitutes the "customer experience" in terms of application performance so that service levels can be verified against measurable and relevant data in a true end-to-end manner across both fixed and wireless networks Presents probe and agent technology Features a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis - this will be of particular interest to practitioner Analyses which elements are required in order to deliver multimedia services across 2nd and 3rd generation mobile networks Details the components of data networking that will assist in guaranteeing service level performance Essential reading for Wireless and IP data network professionals/practitioners, network managers and architects, technical consultants, quality assessment engineers, infrastructure vendors, application developers, portal designers, wireline operators, lecturers, postgraduates, senior undergraduate students and industry trainees.

For networking and RF/wireless engineers, and graduate students who want a solid overview of voice over WLANs/VoIP technology (wireless local area networks / voice over internet protocol), this book covers voice coding, packet loss, delay and 'jitter', and 'echo' control, and shows how to combine both WLAN and VoIP technology to create effective voice over WLAN systems. Finneran also describes how to integrate voice over WLAN systems with cellular networks. This is not just another WLAN-only book nor a VoIP-only book; instead, it integrates both topics into a coherent whole. * Gives complete details on integrating voice and data services on WLANs, including wide area networks * Explores quality of service (QoS) and security issues * Step-by-step descriptions of how to plan and implement voice over WLAN networks
