This book focuses on the design and analysis of protocols for cooperative wireless networks, especially at the medium access control (MAC) layer and for crosslayer design between the MAC layer and the physical layer. It highlights two main points that are often neglected in other books: energy-efficiency and spatial random distribution of wireless devices. Effective methods in stochastic geometry for the design and analysis of wireless networks are also explored. After providing a comprehensive review of existing studies in the literature, the authors point out the challenges that are worth further investigation. Then, they introduce several novel solutions for cooperative wireless network protocols that reduce energy consumption and address spatial random distribution of wireless nodes. For each solution, the book offers a clear system model and problem formulation, details of the proposed cooperative schemes, comprehensive performance analysis, and extensive numerical and simulation results that validate the analysis and examine the performance under various conditions. The last section of this book reveals several potential directions for the research on cooperative wireless networks that deserve future exploration. Researchers, professionals, engineers, and consultants in wireless communication and mobile networks will find this book valuable. It is also helpful for technical staff in mobile network operations, wireless equipment manufacturers, wireless communication standardization bodies, and governmental regulation agencies.
A self-contained guide to the state-of-the-art in cooperative communications and networking techniques for next generation cellular wireless systems, this comprehensive book provides a succinct understanding of the theory, fundamentals and techniques involved in achieving efficient cooperative wireless communications in cellular wireless networks. It consolidates the essential information, addressing both theoretical and practical aspects of cooperative communications and networking in the context of cellular design. This one-stop resource covers the basics of cooperative communications techniques for cellular systems, advanced transceiver design, relay-based cellular networks, and game-theoretic and micro-economic models for protocol design in cooperative cellular wireless networks. Details of ongoing standardization activities are also included. With contributions from experts in the field divided into five distinct sections, this easy-to-follow book delivers the background needed to develop and implement cooperative mechanisms for cellular wireless networks. Professor Ekram Hossain discusses the book:
Compared with conventional communications, cooperative communication allows multiple users in a wireless network to coordinate their packet transmissions and share each other's resources, thus achieving high-performance gain and better service coverage and reliability. Energy Efficient Cooperative Wireless Communication and Networks provides a comprehensive look at energy efficiency and system design of cooperative wireless communication. Introducing effective cooperative wireless communication schemes, the book supplies the understanding and methods required to improve energy efficiency, reliability, and end-to-end protocol designs for wireless communication systems. It explains the practical benefits and limitations of cooperative transmissions along with the associated designs of upper-layer protocols, including MAC, routing, and transport protocol. The book considers power efficiency as a main objective in cooperative communication to ensure quality-of-service (QoS) requirements. It explains how to bring the performance gain at the physical layer up to the network layer and how to allocate network resources dynamically through MAC/scheduling and routing to trade off the performance benefits of given transmissions against network costs. Because the techniques detailed in each chapter can help readers achieve energy efficiency and reliability in wireless networks, they have the potential to impact a range of industry areas, including wireless communication, wireless sensor networks, and ad hoc networks. The book includes numerous examples, best practices, and models that capture key issues in real-world applications. Along with algorithms and tips for effective design, the book supplies the understanding you will need to achieve high-performing and energy efficient wireless networks with improved service coverage and reliability.
Cooperation in Wireless Networks: Principles and Applications covers the underlying principles of cooperative techniques as well as several applications demonstrating the use of such techniques in practical systems. The book is written in a collaborative manner by several authors from Asia, America, and Europe. This book puts into one volume a comprehensive and technically rich appraisal of the wireless communications scene from a cooperation point of view.
In the past decade, cooperative wireless networks have emerged as a promising technology that allows wireless devices to take advantage of diversity and link adaptation. In this thesis, we focus on the design and analysis of the medium access control (MAC) layer for the cooperative wireless networks, aiming at two main issues in this field: relay selection under mobility and incentive-based allocation for relaying packets. Specifically, we proposed and analysed 1) an intelligent cooperative MAC protocol to select stable helpers to provide better throughput; 2) two coordination schemes for multiple helpers to tradeoff the diversity advantage and transmission delay; 3) a moneyless incentive scheme which can stimulate the agreement of cooperation; and 4) three monetary incentive allocation mechanisms to stimulate cooperative relaying while maintaining the desired properties. Firstly, our proposed cooperative MAC protocol, referred as PTCoopMAC, can make use of the out-of-date information from the overheard signals to select the optimal stable helper to improve the system throughput. Secondly, we analysed the unconditional relaying success probability for a wireless diversity system with multiple random moving helpers. One Aloha-based and one timer-based coordination schemes were designed to balance the success probability and transmission delay. Thirdly, the moneyless incentive scheme for one cooperative pair transmission can tune up and down the channel access probability of the helper and the source as the reward and payment, respectively. We further provided the conditions on how to select the tuning factors to reach the cooperation agreement. Finally, we proposed three monetary incentive allocation mechanisms towards different design goals. The Vickrey-Clarke-Groves (VCG)-based mechanism aims at efficiency in social welfare; the probabilistic entrance auction (PEA) mechanism targets at lowering the computational effort; and the randomized (RND) mechanism attempts to strike a balance between the two mechanisms. All the proposed solutions were extensively evaluated by simulations. The results demonstrated that our solutions successfully addressed the challenges posed by user mobility and incentive for the cooperative wireless networks. The quality of service (QoS) can be significantly improved by properly incorporating cooperation among user devices.
