Book Description
"Energy efficiency is an important issue for wireless networks since it extends the lifetime of a wireless network and improves quality of service (QoS). Therefore, the overall objective of this dissertation is to develop energy efficient schemes and medium access control (MAC) protocols for wireless networks in the presence of fading channels while satisfying network constraints and user defined QoS requirements"--Abstract, leaf iv.

Book Description
With modern communication networks continuing to grow in traffic, size, complexity, and variety, control systems are critical to ensure quality and effectively manage network traffic. Providing a thorough and authoritative introduction, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control examines the theory, architectures, and technologies needed to implement quality of service (QoS) in a wide variety of communication networks. Based on years of research and practical experience, this book examines the technical concepts underlying the design, implementation, research, and invention of both wired and wireless networks. The author builds a strong understanding of general concepts and common principles while also exploring issues that are specific to wired, cellular, wireless ad hoc, and sensor networks. Beginning with an overview of networks and QoS control, he systematically explores timely areas such as Lyapunov analysis, congestion control of high-speed networks, admission control based on hybrid system theory, distributed power control of various network types, link state routing using QoS parameters, and predictive congestion control. The book also provides a framework for implementing QoS control using mote hardware. Providing a deeply detailed yet conveniently practical guide to QoS implementation, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control is the perfect introduction for anyone new to the field as well as an ideal reference guide for seasoned network practitioners.

Book Description
Since the early 1990s, the wireless communications field has witnessed explosive growth. The wide range of applications and existing new technologies nowadays stimulated this enormous growth and encouraged wireless applications. The new wireless networks will support heterogeneous traffic, consisting of voice, video, and data (multimedia). This necessitated looking at new wireless generation technologies and enhance its capabilities. This includes new standards, new levels of Quality of Service (QoS), new sets of protocols and architectures, noise reduction, power control, performance enhancement, link and mobility management, nomadic and wireless networks security, and ad-hoc architectures. Many of these topics are covered in this textbook. The aim of this book is research and development in the area of broadband wireless communications and sensor networks. It is intended for researchers that need to learn more and do research on these topics. But, it is assumed that the reader has some background about wireless communications and networking. In addition to background in each of the chapters, an in-depth analysis is presented to help our readers gain more R&D insights in any of these areas. The book is comprised of 22 chapters, written by a group of well-known experts in their respective fields. Many of them have great industrial experience mixed with proper academic background.

Book Description
Efficient management of radio resources is crucial in maintaining peak performance of cellular wireless networks under resources constraints. As wireless networks evolve toward 3G/4G and beyond with broadband multimedia services, managing radio resources to satisfy diverse Quality-of-Service requirements is becoming even more critical. Battery energy conservation for portable terminals on the move is another important aspect in wireless networks. Due to the limit on battery life-time, each unit of battery energy saved directly translates to an increase in the value of communication for a subscriber. In this work, we investigate a uplink power control problem for packet-switched data services, with a focus on energy efficiency for mobile terminals. Packet-switched data differ fundamentally from circuit-switched data in the burstiness of traffic and the connectionless nature of communications. Based on a utility-maximization approach from microeconomics, we define a probabilistic utility model as a performance metric for a wireless data user, which takes into account both the traffic burstiness and average packet delay requirement. Game-theoretic approach is then utilized to study a distributed power control strategy to simultaneously maximize the utility for each individual user in the system. In general, the problem is mathematically intractable. Using several approximation methods, the problem is reduced into tractable format and is studied both analytically and by simulations. Results show that the proposed power control scheme converges to a unique Nash equilibrium which depends on mobile's location, average packet delay requirement, traffic burstiness, and the mean and variance of the interference and background noise at mobile's base station receiver. The scheme can be easily extended to multi-class user traffic environments. For performance evaluation, we establish two idealized slot-by-slot based power control strategies as performance benchmarks. It's shown that the performance achieved by the proposed scheme is close to those by benchmark schemes. Generally, this work provides a new approach based on approximation techniques for the investigation of uplink power control problem in packet-switched systems. The results and insights generated by this study provide guidance on the efficient management of transmit powers for energy-efficient packet-switched data services in current and future generations of wireless networks.

Book Description
The Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol is widely used in highly dynamic ad-hoc networks because of its generic features. The transmission of reliable energy efficient data is an emerging issue in AOMDV routing as the nodes are prone to link failures and route breaks in highly dynamic ad-hoc networks. In order to eliminate such problems, a novel node disjoint multipath routing protocol called Link Reliable Energy Efficient AOMDV (LR-EE-AOMDV), the extension of a well-known AOMDV, is proposed here to find multiple link reliable energy efficient paths between any source and destination pair for data transmission using metrics such as Path Length, Path-Link Quality Estimator (P-LQE) and a novel Path-Node Energy Estimator (P-NEE).
