Book Description
The advent of ad hoc wireless networks demands fundamental understanding about what they can provide in the way of information transfer as well as what the appropriate architectures are for operating them. Scaling Laws for Ad-Hoc Wireless Networks: An Information Theoretic Approach addresses these questions by presenting various models and results that quantify how their information hauling capacity scales with the number of nodes in the network, and also sheds light on high level architecture design for information transport. Scaling Laws for Ad-Hoc Wireless Networks: An Information Theoretic Approach is an invaluable resource for every network engineer or researcher designing or building ad hoc wireless networks.

Book Description
Hybrid wireless network is a combination of ad hoc network and cellular network. A key question arising in such hybrid wireless networks is what is the per-node data transmission limit of the hybrid wireless network over general fading channels and how the throughput capacity varies with different network setup. To our best knowledge, our research is the first piece of work in literature to take up this challenge. To achieve the maximum per-node throughput, an opportunistic communication strategy together with successive interference cancelation (SIC) technique is proposed in this dissertation. The scaling laws for the throughput capacity over both slow fading channels and fast fading channel are derived, and the closed-form analytical expressions for the outage throughput capacity and ergodic throughput capacity are provided. Our research applies an information theoretic approach to determine the threshold of the data transmission rate in hybrid wireless network. Wireless sensor and actuator networks (WSANs) are applied into microgrid to stabilize the power supply in smart grid. In this dissertation, several sensor selection schemes are heuristically proposed to improve the voltage measurement performance and prolong the sensor network lifetime. First, aiming to accurately monitor the real-time voltage level, we propose an opportunistic sensor selection scheme under equal power allocation and investigate the asymptotic behaviors of the voltage measurement performance. We further address the sensor selection scheme under optimal power allocation. Besides, we present the studies on improving the power efficiency with the aid of voltage sensor selection. As a paradigm of the incoming smart grid, vehicle-to-grid (V2G) has been proposed as a solution to increase the adoption rate of plug-in hybrid electric vehicles (PHEVs). In this dissertation, we investigate the energy management strategies for PHEVs via bidirectional V2G. We first follow a cost-conscious approach from the PHEV owner point of view. We prove that a state-independent four-threshold feedback policy is optimal for PHEV battery charging/discharging based on stochastic inventory theory. Further, from the distribution system operator point view, we aim to shave the peak load and flatten the overall load profile. To this end, we propose an optimal PHEV charging scheme and derive a reminiscent of "water-filling" solution. Finally, based on the present researches on the capacity and optimization of hybrid and smart grid wireless networks, we propose two future research directions. First, we propose the future works about the throughput capacity of hybrid wireless networks with hexagon cell structure and Poisson Point Process (PPP) distributed base station. Second, we discuss the future research topic on the throughput capacity of cooperative-diversity networks over fading channels.

Book Description
This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.

Book Description
Middleware is a critical foundation needed to leverage the development of a wide range of mobile and ubiquitous applications. Intrinsic challenges when building such middleware require the combination of expertise from areas like distributed systems, networking, software engineering, and application development. This textbook provides a comprehensive introduction to the main fundamental problems, technologies, paradigms, and solutions of concern to developers of middleware for mobile environments. The contributions are grouped into four parts, on networking and programming issues, communication models, middleware issues, and application issues. Each chapter is structured as a self-contained tutorial, presenting an overview of a specific topic and the state-of-the-art solutions for the related problems. In addition, the book also includes an authoritative reference list. The material has been successfully used in several thematic training schools organized by the ESF MiNEMA (Middleware for Network Eccentric and Mobile Applications) program, and the book's organization and presentation is ideal for an advanced course on middleware.

Book Description
A wireless sensor network (WSN) uses a number of autonomous devices to cooperatively monitor physical or environmental conditions via a wireless network. Since its military beginnings as a means of battlefield surveillance, practical use of this technology has extended to a range of civilian applications including environmental monitoring, natural disaster prediction and relief, health monitoring and fire detection. Technological advancements, coupled with lowering costs, suggest that wireless sensor networks will have a significant impact on 21st century life. The design of wireless sensor networks requires consideration for several disciplines such as distributed signal processing, communications and cross-layer design. Wireless Sensor Networks: Signal Processing and Communications focuses on the theoretical aspects of wireless sensor networks and offers readers signal processing and communication perspectives on the design of large-scale networks. It explains state-of-the-art design theories and techniques to readers and places emphasis on the fundamental properties of large-scale sensor networks. Wireless Sensor Networks: Signal Processing and Communications : Approaches WSNs from a new angle – distributed signal processing, communication algorithms and novel cross-layer design paradigms. Applies ideas and illustrations from classical theory to an emerging field of WSN applications. Presents important analytical tools for use in the design of application-specific WSNs. Wireless Sensor Networks will be of use to signal processing and communications researchers and practitioners in applying classical theory to network design. It identifies research directions for senior undergraduate and graduate students and offers a rich bibliography for further reading and investigation.
