Wireless sensor networks have the potential to become the third wireless revolution after wireless voice networks in the 80s and wireless data networks in the late 90s. Unfortunately, radio power consumption is still a major bottleneck to the wide adoption of this technology. Different directions have been explored to minimize the radio consumption, but the major drawback of the proposed solutions is a reduced wireless link robustness. The primary goal of Architectures and Synthesizers for Ultra-low Power Fast Frequency-Hopping WSN Radios is to discuss, in detail, existing and new architectural and circuit level solutions for ultra-low power, robust, uni-directional and bi-directional radio links. Architectures and Synthesizers for Ultra-low Power Fast Frequency-Hopping WSN Radios guides the reader through the many system, circuit and technology trade-offs he will be facing in the design of communication systems for wireless sensor networks. Finally, this book, through different examples realized in both advanced CMOS and bipolar technologies opens a new path in the radio design, showing how radio link robustness can be guaranteed by techniques that were previously exclusively used in radio systems for middle or high end applications like Bluetooth and military communications while still minimizing the overall system power consumption.

This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature.A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle-to-infrastructure communications.This book offers useful insights into protocol design and inspires a new line of thinking in performance improvements for safety applications in vehicular networks. It is a valuable resource for professionals, researchers, or advanced-level students working in vehicular networks or quality of service.

Old Wires and New Waves- The History of the Telegraph, Telephone and Wireless By Alvin F. Harlow. Originally published in 1936. FOREWORD: THERE may be those who will think that a disproportionate amount of space is given in this book to the early history of the telegraph, as against the remarkable technical develop ments of the past quarter or half century. May it be suggested that the birth and infancy of ideas are intrinsically more note worthy, more important, than their middle age The centuries of groping for a method of quick communication, the one long century of mans striving to make electricity his servant, the pioneer days of the telegraph, when not only it but all America was simple and crude these are to most folk to-day so exotic, the last-named phase is to the student so significant a picture of the youth of American society and the nation, that, in the judgment of the author, they should be dealt with in detail for the benefit of a generation which knows them not. On the other hand, the rapid developments in telegraph, tele phone, and wireless in recent days are described at length in newspapers and magazines as they appear and they come so swiftly and we are so inured to them that the astounding inven tion of yesterday has to-day become a commonplace, and to morrow is superseded by something still more miraculous. It is therefore scarcely worth while for so slowly built and so final a publication as a book to attempt chronicling all the - minor de tails of recent progress in communication, especially since these matters become so complex and so abstruse that full explanation of their development and functioning would be too complicated for non-technically minded readers.Nevertheless, these modern developments have not been neglected, but are treated as fully as space limitations and the need for clarity seem to dictate. As usual, I have leaned heavily in my research upon the original documents and other materials in the collections of the New York Public Library and the New York Historical So ciety. The latters Henry ORielly Collection is one of the most valuable telegraph sources in existence. The great communications companies have all been very help ful. Through the good offices of Mr. William P. Banning, Assis tant Vice-President of the American Telephone and Telegraph Company, I spent many hours in personally conducted tours through that companys three huge operating buildings in New York City, any one of which is worth a trip to New York to see I was overwhelmed with pamphlets, reports, documents, magazine articles, and books and any and all photographs I desired for illustrations were at my disposal. Mr. Langdon, the librarian Miss Winburg, keeper of the photographs Messrs. Fowler and Mills of the Bell Telephone Laboratories, Rood and Lea of the Long Lines Building Carl and Sedgwick of the New York Telephone Company, all gave their assistance with the courtesy characteristic of the organization. Mr. E. W. Goode, of the publicity department of the Inter national Telephone and Telegraph Corporation, supplied all the data at his command, loaned books not to be found elsewhere, procured permission for me to see the companys operating rooms, gave me whatever photographs I desired, and searched the country over for older ones which were not in his files. The Radio Corporation of America, through Messrs. Galvin, Wright, and Weaver, was also veryhelpful. I was conducted through its operating building and was supplied with photographs and technical information as needed...

Around the developing world, political leaders face a dilemma: the very information and communication technologies that boost economic fortunes also undermine power structures. Globally, one in ten internet users is a Muslim living in a populous Muslim community. In these countries, young people are developing their political identities-including a transnational Muslim identity-online. In countries where political parties are illegal, the internet is the only infrastructure for democratic discourse. In others, digital technologies such as mobile phones and the internet have given key actors an information infrastructure that is independent of the state. And in countries with large Muslim communities, mobile phones and the internet are helping civil society build systems of political communication independent of the state and beyond easy manipulation by cultural or religious elites. This book looks at the role that communications technologies play in advancing democratic transitions in Muslim countries. As such, its central question is whether technology holds the potential to substantially enhance democracy. Certainly, no democratic transition has occurred solely because of the internet. But, as Philip Howard argues, no democratic transition can occur today without the internet. According to Howard, the major (and perhaps only meaningful) forum for civic debate in most Muslim countries today is online. Activists both within diasporic communities and within authoritarian states, including Iran, Saudi Arabia and Pakistan, are the drivers of this debate, which centers around issues such as the interpretation of Islamic texts, gender roles, and security issues. Drawing upon material from interviews with telecommunications policy makers and activists in Azerbaijan, Egypt, Tajikistan and Tanzania and a comparative study of 74 countries with large Muslim populations, Howard demonstrates that these forums have been the means to organize activist movements that have lead to successful democratic insurgencies.

This book throws a lifeline to designers wading through mounds of antenna array patents looking for the most suitable systems for their projects. Drastically reducing the research time required to locate solutions to the latest challenges in automotive communications, it sorts and systematizes material on cutting-edge antenna arrays that feature multi-element communication systems with enormous potential for the automotive industry. These new systems promise to make driving safer and more efficient, opening up myriad applications, including vehicle-to-vehicle traffic that prevents collisions, automatic toll collection, vehicle location and fine-tuning for cruise control systems. This book's exhaustive coverage begins with currently deployed systems, frequency ranges and key parameters. It proceeds to examine system geometry, analog and digital beam steering technology (including "smart" beams formed in noisy environments), maximizing signal-to-noise ratios, miniaturization, and base station technology that facilitates in-car connectivity while on the move. An essential guide for technicians working in a fast-developing field, this new volume will be warmly welcomed as a powerful aid in their endeavors.

Over the past decades, fault diagnosis (FDI) and fault tolerant control strategies (FTC) have been proposed based on different techniques for linear and nonlinear systems. Indeed a considerable attention is deployed in order to cope with diverse damages resulting in faults occurrence.

Power consumption becomes the most important design goal in a wide range of electronic systems. There are two driving forces towards this trend: continuing device scaling and ever increasing demand of higher computing power. First, device scaling continues to satisfy Moore's law via a conventional way of scaling (More Moore) and a new way of exploiting the vertical integration (More than Moore). Second, mobile and IT convergence requires more computing power on the silicon chip than ever. Cell phones are now evolving towards mobile PC. PCs and data centers are becoming commodities in house and a must in industry. Both supply enabled by device scaling and demand triggered by the convergence trend realize more computation on chip (via multi-core, integration of diverse functionalities on mobile SoCs, etc.) and finally more power consumption incurring power-related issues and constraints.

This book presents a time-delay approach to the analysis and synthesis of networked control systems (NCSs) under communication constraints. Differently from other approaches, the time-delay approach to NCSs allows communication delays to be larger than the sampling intervals in the presence of scheduling protocols. The book starts from a comprehensive introduction to three main approaches to sampled-data and networked control. It then focuses on time-delay approach, and the modelling of the closed-loop systems in the form of time-delay system. It presents discontinuous (in time) Lyapunov functional constructions that are efficient for NCSs in the presence of communications delays. Further, it highlights time-delay approaches developed to model and analyze NCSs under communication constraints, with a particular focus on dynamic quantization, round-robin, try-once-discard and stochastic protocols. The results are first presented for the continuous-time NCSs and then extended to discrete-time NCSs. Discussing recent developments in Lyapunov-based analysis of NCSs under communication constraints, the book is a valuable resource for researchers interested in sampled-data and networked control, and time-delay systems, as well as for graduate students in automatic control and systems theory.

This book addresses the emerging technology for Orthogonal Frequency Division Multiple Access (OFDMA), covering OFDMA physical layer as well as network technology. The book also includes information on IEEE 802.16e and WiMAX networks and also offers a comparison with other OFDMA technologies.

OFDMA is the fastest growing area in the wireless marketplace, and the backbone of systems used in WiMAX. WiMAX is the technology that enables wireless users to communicate at any time from any location without having to find a WiFi hotspot.

Securing Emerging Wireless Systems: Lower-layer Approaches aims to fill a growing need in the research community for a reference that describes the lower-layer approaches as a foundation towards secure and reliable wireless systems. Whereas most of the references typically address cryptographic attacks by using conventional "network security" approches for securing wireless systems, the proposed book will be differentiated from the rest of the market by its focus on non-cryptographic attacks that cannot easily be addressed by using traditional methods, and further by presenting a collection of defense mechanisms that operate at the lower-layers of the protocol stack and can defend wireless systems before the effects of attacks propagate up to higher-level applications and services.

The book will focus on fundamental security problems that involve properties unique to wireless systems, such as the characteristics of radio propagation, or the location of communicating entities, or the properties of the medium access control layer. Specifically, the book provides detection mechanisms and highlights defense strategies that cope with threats to wireless localization infrastructure, attacks on wireless networks that exploit entity identity (i.e. spoofing attacks), jamming and radio interference that can undermine the availability of wireless communications, and privacy threats where an adversary seeks to infer spatial and temporal contextual information surrounding wireless communications. Additionally, the authors explore new paradigms of physical layer security for wireless systems, which can support authentication and confidentiality services by exploiting fading properties unique to wireless communications.

This book presents the most important fault-tolerant distributed programming abstractions and their associated distributed algorithms, in particular in terms of reliable communication and agreement, which lie at the heart of nearly all distributed applications. These programming abstractions, distributed objects or services, allow software designers and programmers to cope with asynchrony and the most important types of failures such as process crashes, message losses, and malicious behaviors of computing entities, widely known under the term "Byzantine fault-tolerance". The author introduces these notions in an incremental manner, starting from a clear specification, followed by algorithms which are first described intuitively and then proved correct. The book also presents impossibility results in classic distributed computing models, along with strategies, mainly failure detectors and randomization, that allow us to enrich these models. In this sense, the book constitutes an introduction to the science of distributed computing, with applications in all domains of distributed systems, such as cloud computing and blockchains. Each chapter comes with exercises and bibliographic notes to help the reader approach, understand, and master the fascinating field of fault-tolerant distributed computing.
