Energy Efficiency: Lessons Learned from Success Stories
by Gary Stuggins Alexander Sharabaroff Yadviga SemikolenovaEnergy efficiency is an important factor in an economy, since it helps meet energy needs, decrease costs, and lower environmental impacts. A review of the evolution of energy intensity in European and Former Soviet Union countries indicates a positive trend: high-energy-intensity countries have now reached the level of medium-energy-intensity economies 15 years earlier, and in the same period, medium-energy-intensity ones had similarly evolved to levels of low-energy-intensity. At the same time, the fast transitioning economies of Central Europe converged towards similar levels of energy intensities, in line with EU Directives, while successful EU-15 countries managed to maintain economic growth while keeping energy use flat. This report looks at how countries effect the transition from high- to medium- to low-energy-intensity, exploring whether leapfrogging is possible (it’s not) and what policies can be particularly helpful. Some of the lessons include: energy prices tend to evolve from subsidized levels to full-cost-recovery to full-cost-recovery-plus environmental externalities; industrial energy efficiency is often the starting point, with privatization and competition driving companies to reduce production costs, including energy; successful countries excell at governance (setting targets, building institutional capacity, creating and improving the legal and regulatory framework, and monitoring and evaluating); households tended to be the last, and most difficult, area of reform, starting with pricing improvements, outreach campaigns, financing programs, and building certificates programs.

Energy Efficient Computation Offloading in Mobile Edge Computing (Wireless Networks)
by Ying Chen Ning Zhang Yuan Wu Sherman ShenThis book provides a comprehensive review and in-depth discussion of the state-of-the-art research literature and propose energy-efficient computation offloading and resources management for mobile edge computing (MEC), covering task offloading, channel allocation, frequency scaling and resource scheduling. Since the task arrival process and channel conditions are stochastic and dynamic, the authors first propose an energy efficient dynamic computing offloading scheme to minimize energy consumption and guarantee end devices’ delay performance. To further improve energy efficiency combined with tail energy, the authors present a computation offloading and frequency scaling scheme to jointly deal with the stochastic task allocation and CPU-cycle frequency scaling for minimal energy consumption while guaranteeing the system stability. They also investigate delay-aware and energy-efficient computation offloading in a dynamic MEC system with multiple edge servers, and introduce an end-to-end deep reinforcement learning (DRL) approach to select the best edge server for offloading and allocate the optimal computational resource such that the expected long-term utility is maximized. Finally, the authors study the multi-task computation offloading in multi-access MEC via non-orthogonal multiple access (NOMA) and accounting for the time-varying channel conditions. An online algorithm based on DRL is proposed to efficiently learn the near-optimal offloading solutions.Researchers working in mobile edge computing, task offloading and resource management, as well as advanced level students in electrical and computer engineering, telecommunications, computer science or other related disciplines will find this book useful as a reference. Professionals working within these related fields will also benefit from this book.

Energy Efficient Full Duplex Wireless Communication Systems (Wireless Networks)
by Xu Zhu Jingjing Wang Zhongxiang Wei Sumei SunIn an effort to overcome the spectral efficiency loss and high latency by half-duplex (HD), full-duplex (FD) has attracted extensive attention in industry and academia. With signal transmitted and received simultaneously over the same frequency, FD can approximately double the SE over HD. More than that, by enabling the capability of simultaneous transmission-and-reception for communication nodes, full duplex (FD) is a key enabler for many 5G techniques, including but not limited to integrated sensing and communication, low-latency relaying, concurrent bi-directional uplink and downlink transmission, ect. Nevertheless, in FD communications, both transmit and receive radio frequency (RF) chains are activated for exchanging data, and additional power is triggered by self-interference cancellation. As FD requires much higher power consumption than that of half duplex (HD), it is against the green evolution requirement proposed by the future communication systems. To address the critical high-power challenge in applying FD communications, this book will introduce the fundamentals and algorithm designs for energy-efficient FD design. This book will first discuss the principle of energy-efficient communications, which aims to make a good balance between communication performance and system energy consumption. Then, this book will discuss different self-interference cancellation schemes, including passive suppression, analogue cancellation and digital cancellation for FD communications, from the prospective of energy efficiency. Subsequently, this book will present some edge-cutting energy efficiency-oriented FD solutions, including adaptive transmission power adaptation, wireless power transfer FD relaying, bi-directional FD distributed antenna systems, from the perspective of algorithm design and performance analysis.

Energy Efficient Spectrum Resources Usage in WPANs: IEEE 82.15.4 MAC Sub-layer Protocols (River Publishers Series in Communications and Networking)
by Periklis Chatzimisios Luís Miguel Borges Norberto Barroca Fernando José VelezWireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.
