Book Description
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.

Book Description
Energy efficient cooperative diversity techniques are investigated in this thesis with the aim of improving the energy efficiency of wireless sensor networks (WSNs) in the presence of additive white Gaussian noise (AWGN) and frequency-selective Rayleigh fading without degrading the reliability of data transmission. The studies reported mainly focus the theoretical aspects of aiming establishing the feasibility of employing cooperative diversity techniques in WSNs (subject to AWGN and frequency-selective Rayleigh fading) to effectively improve the network’s energy efficiency in the physical layer. With improvements to energy efficiency, the operational lifetime of WSN applications operating in indoor environments can be prolonged.A mathematical model of a single input single output (SISO) wireless communication system with direct sequence spread spectrum (DSSS) transceivers in the presence of AWGN and frequency-selective Rayleigh fading is proposed, modelled, theoretically analysed and simulated. In order to save the transmit energy consumption of sensor nodes, DSSS transceivers with chip-interleaving signal processing are considered as well. Analytical expressions of bit error rate (BER) in closed form are derived and analysed for wireless systems using DSSS transceivers, with or without chip-interleaving signal processing. Using the derived BER algorithms, the BER performances of virtual-multiple-input-single-output (vMISO), decode-and-forward (DF) and adaptive decode-and-forward (aDF) cooperation in WSNs subject to AWGN and frequency-selective Rayleigh fading are investigated as well.Performance evaluations are carried out based on the BER expressions and energy consumption models of vMISO, DF and aDF cooperation in terms of their optimal transmit power allocation and partner selection region. Because the energy expenditure of a sensor node can also be reduced by using the chip-interleaving signal processing, cooperative diversity (vMISO and DF) and chip-interleaved techniques are employed in combination to further improve the energy efficiency of WSNs operating over AWGN channels with frequency-selective Rayleigh fading. Furthermore,several simple partner selection heuristics are developed for energy efficient vMISO and DFcooperative schemes, which will enable resource-constrained sensor nodes to make cooperation decisions independently and autonomously. In summary, the analytical and simulation results demonstrate that the energy efficiency of WSNs subject to AWGN and frequency-selective Rayleigh fading can be significantly improved by implementing the cooperative diversity techniques and the chip interleaving technique, individually or in combination.

Book Description
With the advances in small and low-cost radio transceivers and RF front-ends development, the possibility of applying ubiquitous and non-invasive sensors integrated into user's daily clothing and living activities seems more feasible. The ability to share data increases the usefulness of personal information devices, providing features not possible with independent isolated devices. Current wireless sensor solutions are limited in that they do not provide the means to overcome obstacles and shadowing of propagating radio waves. Thus for reliable communications an increase in power consumption is required, reducing battery life. This book addresses the limitations outlined above by designing efficient and compact antenna systems. These systems will be cooperative and also aware of the surrounding environment and neighboring units, providing efficient and low power wireless connectivity for personal area network (PAN) and body area network (BAN) applications. - Analysis of wearable antenna design and performance - Addresses the Influence of body-worn antennas on radio channels and radio device performance from a power and error rate perspective. - Cooperative networking principles applied to body area networks, showing the pros and cons of such concepts - Real life case scenarios using ECG sample signals for potential application to healthcare monitoring.

Book Description
The last decade has witnessed an unprecedented development and growth in global wireless communications systems, technologies and network “traffic” generated over network infrastructures. This book presents state-of-the-art energy-efficient techniques, designs and implementations that pertain to wireless communication networks such as cellular networks, wireless local area networks (WLANs) and wireless ad hoc networks (WAHNs) including mobile ad hoc networks (MANETs), and wireless sensor networks (WSNs) as they are deployed across the world to facilitate “always on” reliable high-speed wireless access from anywhere, at anytime to accommodate the new paradigm of the “Internet of Things” (IoT). The pervasive and exponential growth of Wi-Fi and the impact of bandwidth-intensive applications on the energy consumption of Wi-Fi-enabled devices are discussed along with energy harvesting as an advantageous option to power WAHNs. The book aims to serve as a useful reference for researchers, students, regulatory authorities, and educators.
