Download Adaptation and Cross Layer Design in Wireless Networks Book in PDF, ePub and Kindle
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.

Download Cross-layer Power and Rate Adaptation Techniques for Wireless Networks Book in PDF, ePub and Kindle
Packet scheduling using variable power and variable rate is very important techniques in wireless networks due to limited bandwidth resources and increasing demand for high data rates. Time-varying incoming traffic and random channel gain make the scheduling decision very challenging. Current packet adaptation techniques deal with the single layer optimizations in each layer separately, which results in suboptimal performance when system-level performance parameters are considered. This book discusses both the optimal and the reduced-complexity heuristic cross-layer adaptation techniques over time-varying correlated fading channels. Due to the inherent dynamic nature of the packet scheduling, the problem are formulated from the cross-layer optimization viewpoint using Markov decision processes framework, by considering both the physical and the data link layers optimization objectives. The objective is to jointly maximize throughput, and minimize power and buffering delay while maintaining packet overflow and bit error rate requirements. The book provides crucial insight on the trade-off among the various quality-of-service (QoS) objectives.

Download Using Cross-Layer Techniques for Communication Systems Book in PDF, ePub and Kindle
Although the existing layering infrastructure--used globally for designing computers, data networks, and intelligent distributed systems and which connects various local and global communication services--is conceptually correct and pedagogically elegant, it is now well over 30 years old has started create a serious bottleneck. Using Cross-Layer Techniques for Communication Systems: Techniques and Applications explores how cross-layer methods provide ways to escape from the current communications model and overcome the challenges imposed by restrictive boundaries between layers. Written exclusively by well-established researchers, experts, and professional engineers, the book will present basic concepts, address different approaches for solving the cross-layer problem, investigate recent developments in cross-layer problems and solutions, and present the latest applications of the cross-layer in a variety of systems and networks.

Download Cross Layer Optimizations for Performance Enhancement of Wireless Networks Book in PDF, ePub and Kindle
In this dissertation, we focus on designing several cross-layer optimizations to boost the performance of wireless networks. We categorize our efforts into two directions: (a) improvement of spatial reusability and multi-hop performance via Directional Antennas, and (b) analysis and optimization of the IEEE 802.11 multi-rate networks. Since existing protocols are incapable of fully exploiting the benefits of a directional antenna system, we propose a, broadcast and routing protocol for such systems. All our proposals assume cross layer interaction between the Network, MAC and PHY layers. Next, we analyze multi-rate networks in the context of IEEE 802.11 DCF networks and propose an analytical model to study the link-delay characteristics of such systems. We then propose an online algorithm Time Fair CSMA (TFCSMA), for guaranteeing air-time fairness and thereby mitigating the recently observed rate anomaly problem of IEEE DCF multi-rate networks. Following the design of TFCSMA, we concentrate on the problem of rate adaptation for time-varying wireless channels. We thoroughly investigate the impact of transmission rate on the performance of a wireless link. We then propose Stochastic Automata Rate Adaptation Algorithm (SARA). SARA is inspired by Stochastic Learning Automata (SLA), a machine learning technique for adaptation in random environments. As opposed to the previous work in this area, SARA is ideally suited for both stationary and non-stationary channel environments and is completely compatible with the existing IEEE 802.11 MAC standard.

This innovative book sets forth two promising wireless approachesthat support high-quality, high-speed data and multimediaservice-multiple antenna technologies and cross layer transmitteradaptation designs-while highlighting the relationships andinteractions between them. The latest advanced technologies ofchannel adaptation techniques for wireless communication systemswith multiple antennas are thoroughly investigated. The book is divided into three parts, first giving readers a goodfoundation in underlying theory, then exploring applications aswell as advanced topics: * Part 1 examines theoretical aspects of channel adaptation inwireless communications for point-to-point and multi-user systemswith multiple antennas * Part 2 focuses on the applications of the channel-adaptivetechnologies in practical systems such as UMTS * Part 3 delves into topics such as multi-user scheduling forwideband systems, combined queuing theory and information theory,and ad hoc routing Using a hands-on, practical approach, Channel Adaptive Technologiesand Cross Layer Designs for Wireless Systems with Multiple Antennasthoroughly covers detailed design considerations that help readersunderstand how to apply theory to real-world systems. Emphasisthroughout the book is on joint optimization across differentlayers of a communications system based on an integrated approach.Examples of popular wireless systems, such as TDMA, wideband CDMA(UMTS), and HSDPA, are used throughout as practical illustrations.Each chapter ends with a summary that reviews key points and a setof problems that lets readers test their knowledge and continue todevelop their skills as they progress to new topics. Figures andtables are also used extensively to help readers visualize complextheory and systems. Combining theory, design, and application into one integratedapproach, this is a superior reference for advanced communicationstheory courses.
