Book Description
Adaptive techniques play a key role in modern wireless communication systems. The concept of adaptation is emphasized in the Adaptation in Wireless Communications Series through a unified framework across all layers of the wireless protocol stack ranging from the physical layer to the application layer, and from cellular systems to next-generation wireless networks. Adaptation and Cross Layer Design in Wireless Networks is devoted to adaptation in the data link layer, network layer, and application layer. The book presents state-of-the-art adaptation techniques and methodologies, including cross-layer adaptation, joint signal processing, coding and networking, selfishness in mobile ad hoc networks, cooperative and opportunistic protocols, adaptation techniques for multimedia support, self –organizing routing, and tunable security services. It presents several new theoretical paradigms and analytical findings which are supported with various simulation and experimental results. Adaptation in wireless communications is needed in order to achieve high capacity and ubiquitous communications. The current trend in wireless communication systems is to make adaptation dependent upon the state of the relevant parameters in all layers of the system. Focusing on simplified cross layer design approaches, this volume describes advanced techniques such as adaptive resource management, adaptive modulation and coding, 4G communications, QoS, diversity combining, and energy and mobility aware MAC protocols. The first volume in the series, Adaptive Signal Processing in Wireless Communications (cat no.46012) covers adaptive signal processing at the physical layer.

Book Description
Power control has become an important aspect of any communication system such as cellular networks, wireless LANs and DSL modems. Power control offers many benefits: optimizing the SNR in the link, conserving the battery life and minimizing the interference between the transmitter terminals. Power control is recognized as adaptive control. Here, we consider solely the optimization of the battery life and assessing the total energy cost in power control. The power control problem is formulated in a communication link with a static complex gain and a single transmitter, corrupted by complex normal noise. The channel estimate is computed by least squares using pilot tones. Then the signal power and noise power estimates are calculated, and ultimately the SNR estimate and its statistical properties. Based on this SNR estimate, an appropriate power level can be chosen for data transmission. The total energy cost of the power control process is formulated with aid of the statistics of SNR estimate. The cost is found to exhibit a pathological behavior, where a transmitter should send an infinite number of pilot tones at zero transmitted power to minimize the non-zero total energy cost of power control. When the transmitter is moving, however, this pathological behavior disappears. Next we look at the power control problem from the perspective of ODAC. The dual feature of the problem is that to probe the link effectively, the transmitter must use a large power level, but this affects the control process negatively as it increases the overall energy cost. A balance between the two aspects must be obtained. Assuming some a priori information about the fade is known, we use SDP, with aid of the information state that describes the evolution of the fade's statistics as measurements are obtained and controls applied, thus acquiring ODAC solutions to the power control problem. The solutions are found to depend greatly on what we know beforehand about the channel, a feature that is not present in current power control algorithms. We also develop heuristics that help reduce the computational demand due to SDP algorithm.

Book Description
In this unique compendium, the general principal of adaptation and its application in communications, especially for bit rate adaptation are considered. Two type of bit rate adaptation are treated -- signal duration and size constellation. When a channel state is relatively good, size constellation adaptation should be used. With state degradation, signal duration is used. The optimal control algorithms maximizing bit rate are constructed, and quantitative characteristics of efficiency are determined for both types separately as well as when they are used jointly. The characteristics are separated into two classes: potential and real ones. The potential demonstrates the limiting possibilities for the system and real shows how much the efficiency decreases, taking into account the influence of real factors.

Book Description
Just a decade ago, many industry luminaries predicted the collapse of the centralized data center and IT structure. In its place would be a more decentralized client/server model built upon the Open Systems Interconnect (OSI) networking architecture. However, client/server never fully realized all of its promises, and OSI floundered. Now, instead of client/server and OSI, we have the Web-based model and TCP/IP. Together, Web-oriented technologies (i.e., browsers, web servers, HTML, Java) and TCP/IP are completely changing how the enterprise views its network. Instead of serving as primarily an internal utility, the enterprise network is now a vital means of delivering products and services and of tying an enterprise more closely to its customers, partners and suppliers. The impact to the very structure of the enterprise network could not be more profound. Providing extensive coverage of planning, networking, LANs, systems management, communications issues and trends, Communications Systems Management Handbook, 6th Edition is your most reliable source for solid, dependable solutions to real-world data communications problems. The tips, strategies, and case-studies provided do more than just save you time and money. They also save your data communications network, and with it your professional life.

Book Description
Competition within the telecommunications companies is growing fiercer by the day. Therefore, it is vital to ensure a high level of quality and reliability within all telecommunications systems in order to guard against faults and the failure of components and network services. Within large scale systems such quality and reliability problems are ever higher. The metrics of Quality and Reliability have to date only been available in journals and technical reports of companies which have designed or produced major parts of systems used in large applications. This book provides a self-contained treatment enabling the reader to be able to produce, define and utilise the metrics of Quality and Reliability required for the design and implementation of a large application such as a world class event as the Olympic Games. An additional outcome is that this book can be used as a guide for producing an ISO standard for large scale Systems such as the Olympic Games. * Provides presentations of techniques used for solving quality and reliability problems in telecommunications networks replete with illustrations of their applications to real-world services and world class events * Individual chapters written by respective international experts within their fields This will prove highly informative for Practising engineers, researchers and telecommunications professionals, academics and graduate students in telecommunications, standards bodies and organisations such as ISO.
