This book introduces the reader to the principles used in the construction of a large range of modern data communication protocols. The approach we take is rather a formal one, primarily based on descriptions of protocols in the notation of CSP. This not only enables us to describe protocols in a concise manner, but also to reason about many of their interesting properties and formally to prove certain aspects of their correctness with respect to appropriate speci?cations. Only after considering the main principles do we go on to consider actual protocols where these principles are exploited. This is a completely new edition of a book which was ?rst published in 1994, where the main focus of many international efforts to develop data communication systems was on OSI - Open Systems Interconnection - the standardised archit- ture for communication systems developed within the International Organisation for Standardization, ISO. In the intervening 13 years, many of the speci?c protocols - veloped as part of the OSI initiative have fallen into disuse. However, the terms and concepts introduced in the OSI Reference Model are still essential for a systematic and consistent analysis of data communication systems, and OSI terms are therefore used throughout. There are three signi?cant changes in this second edition of the book which p- ticularly re?ect recent developments in computer networks and distributed systems.

Every endeavour is covered by some fault, just as ?re is covered by smoke. Therefore one should not give up the work born of his nature, even if such work is full of fault. - The Bhagvad-Gita (18.48) This book is the outcome of the research and developmentcontributions of partners from three different continents, Asia, Europe, America, coming from universities, research centers, industrial partners and SMEs (Small and Medium Enterprise), all of them collaborating in MAGNET (My Adaptive Personal Global Net) and MAGNET Beyond project supported by European Commission within the Sixth Framework Programme (FP6). The project was focusing on a secure user-centric approach developingsecure Personal Networks in multi-network, multi-device, and multi-user environments. The innovative concept of Personal Network (PN), which was introduced and developed in MAGNET, ?nds in this book the ?rst con?rmation of the success that the future of wireless communications is bound to achieve. The importance of this book is not only related to being the ?rst work on PNs, it also gives an overview of operation of a big project, like MAGNET, and in fact the organisation of the book re?ects how then project itself has been structured

Comparative E-Government examines the impact of information and communication technology (ICT) on governments throughout the world. It focuses on the adoption of e-government both by comparing different countries, and by focusing on individual countries and the success and challenges that they have faced. With 32 chapters from leading e-government scholars and practitioners from around the world, there is representation of developing and developed countries and their different stages of e-government adoption. Part I compares the adoption of e-government in two or more countries. The purpose of these chapters is to discern the development of e-government by comparing different counties and their individual experiences. Part II provides a more in-depth focus on case studies of e-government adoption in select countries. Part III, the last part of the book, examines emerging innovations and technologies in the adoption of e-government in different countries. Some of the emerging technologies are the new social media movement, the development of e-participation, interoperability, and geographic information systems (GIS).

Preface Due to the development of hardware technologies (such as VLSI) in the early 1980s, the interest in parallel and distributive computing has been rapidly growingandinthelate1980sthestudyofparallelalgorithmsandarchitectures became one of the main topics in computer science. To bring the topic to educatorsandstudents, severalbooksonparallelcomputingwerewritten. The involvedtextbook IntroductiontoParallelAlgorithmsandArchitectures by F. Thomson Leighton in 1992 was one of the milestones in the development of parallel architectures and parallel algorithms. But in the last decade or so the main interest in parallel and distributive computing moved from the design of parallel algorithms and expensive parallel computers to the new distributive reality the world of interconnected computers that cooperate (often asynchronously) in order to solve di?erent tasks. Communication became one of the most frequently used terms of computer science because of the following reasons: (i) Considering the high performance of current computers, the communi- tion is often moretime consuming than the computing time of processors. As a result, the capacity of communication channels is the bottleneck in the execution of many distributive algorithms. (ii) Many tasks in the Internet are pure communication tasks. We do not want to compute anything, we only want to execute some information - change or to extract some information as soon as possible and as cheaply as possible. Also, we do not have a central database involving all basic knowledge. Instead, wehavea distributed memorywherethe basickno- edgeisdistributedamongthelocalmemoriesofalargenumberofdi?erent computers. The growing importance of solving pure communication tasks in the - terconnected world is the main motivation for writing this book."

Networking Infrastructure for Pervasive Computing: Enabling Technologies & Systems is a comprehensive guide to tomorrow's world of ubiquitous computing where users can access and manipulate information from everywhere at all times.
The emphasis is on networking, systems and standards rather than detailed physical implementation. Addressed are many technical obstacles, such as, connectivity, levels of service, performance, and reliability and fairness. The authors also describe the existing enabling off-the-shelf technologies and its underlying infrastructure known as pervasive networking (PervNet). PervNet ties different sets of smart nodes together enabling them to communicate with each other to provide pervasive computing services to users. Throughout the book, important issues related to scalability, transparency, security, energy management, QoS provisioning, fault tolerance, and disconnected operations are discussed.
This work provides a research and development perspective to the field of PervNet and will serve as an essential reference for network designers, operators and developers.

All-optical networking is generally believed to be the only solution for coping with the ever-increasing demands in bandwidth, such as the World Wide Web application.
Optical backbone networks efficiently achieve a high level of traffic aggregation by multiplexing numerous users on circuit-switched wavelength paths - the so-called wavelength routing approach. In contrast, the reduced level of traffic aggregation in access and metro networks makes wavelength routing solutions not adequate. In these network areas, packet-interleaved optical time-division multiplexing with its finer and more dynamic bandwidth allocation is advocated.
The book presents such an approach, known as photonic slot routing. It illustrates how this approach may provide a cost-effective solution to deploying all-optical transport networks, using today's optical device technology. To that end, the author combines DWDM-technology with fixed slot optical switching, and gives a comprehensive description of this approach in which slots are aligned across the wavelengths to form groups of data-flows that propagate as a whole inside the network. Operating algorithms are developed, and network performance is analyzed, both by means of theoretical analysis and many simulations of sample networks.
This work will be of particular interest to researchers and professionals who are active in photonic networking.

Foreword by Lars Knudsen
"Practical Intranet Security" focuses on the various ways in which an intranet can be violated and gives a thorough review of the technologies that can be used by an organization to secure its intranet. This includes, for example, the new security architecture SESAME, which builds on the Kerberos authentication system, adding to it both public-key technology and a role-based access control service. Other technologies are also included such as a description of how to program with the GSS-API, and modern security technologies such as PGP, S/MIME, SSH, SSL IPSEC and CDSA. The book concludes with a comparison of the technologies.
This book is different from other network security books in that its aim is to identify how to secure an organization's intranet. Previously books have concentrated on the Internet, often neglecting issues relating to securing intranets. However the potential risk to business and the ease by which intranets can be violated is often far greater than via the Internet.
The aim is that network administrators and managers can get the information that they require to make informed choices on strategy and solutions for securing their own intranets.
The book is an invaluable reference for network managers and network administrators whose responsibility it is to ensure the security of an organization's intranet. The book also contains background reading on networking, network security and cryptography which makes it an excellent research reference and undergraduate/postgraduate text book.

Blockchain Technology Solutions for the Security of IoT-Based Healthcare Systems explores the various benefits and challenges associated with the integration of blockchain with IoT healthcare systems, focusing on designing cognitive-embedded data technologies to aid better decision-making, processing and analysis of large amounts of data collected through IoT. This book series targets the adaptation of decision-making approaches under cognitive computing paradigms to demonstrate how the proposed procedures, as well as big data and Internet of Things (IoT) problems can be handled in practice. Current Internet of Things (IoT) based healthcare systems are incapable of sharing data between platforms in an efficient manner and holding them securely at the logical and physical level. To this end, blockchain technology guarantees a fully autonomous and secure ecosystem by exploiting the combined advantages of smart contracts and global consensus. However, incorporating blockchain technology in IoT healthcare systems is not easy. Centralized networks in their current capacity will be incapable to meet the data storage demands of the incoming surge of IoT based healthcare wearables.

This study, written in the context of its first publication in 1970, discusses and documents the invasion of privacy by the corporation and the social institution in the search for efficiency in information processing. Discussing areas such as the impact of the computer on administration, privacy and the storage on information, the authors assess the technical and social feasibility of constructing integrated data banks to cover the details of populations. The book was hugely influential both in terms of scholarship and legislation, and the years following saw the introduction of the Data Protection Act of 1984, which was then consolidated by the Act of 1998. The topics under discussion remain of great concern to the public in our increasingly web-based world, ensuring the continued relevance of this title to academics and students with an interest in data protection and public privacy.

The twentieth century ended with the vision of smart dust: a network of wirelessly connected devices whose size would match that of a dust particle, each one a se- containedpackageequippedwithsensing, computation, communication, andpower. Smart dust held the promise to bridge the physical and digital worlds in the most unobtrusive manner, blending together realms that were previously considered well separated. Applications involved scattering hundreds, or even thousands, of smart dust devices to monitor various environmental quantities in scenarios ranging from habitat monitoring to disaster management. The devices were envisioned to se- organize to accomplish their task in the most ef?cient way. As such, smart dust would become a powerful tool, assisting the daily activities of scientists and en- neers in a wide range of disparate disciplines. Wireless sensor networks (WSNs), as we know them today, are the most no- worthy attempt at implementing the smart dust vision. In the last decade, this ?eld has seen a fast-growing investment from both academia and industry. Signi?cant ?nancial resources and manpower have gone into making the smart dust vision a reality through WSNs. Yet, we still cannot claim complete success. At present, only specialist computerscientists or computerengineershave the necessary background to walk the road from conception to a ?nal, deployed, and running WSN syst

Systematic Design of Sigma-Delta Analog-to-Digital Converters describes the issues related to the sigma-delta analog-to-digital converters (ADCs) design in a systematic manner: from the top level of abstraction represented by the filters defining signal and noise transfer functions (STF, NTF), passing through the architecture level where topology-related performance is calculated and simulated, and finally down to parameters of circuit elements like resistors, capacitors, and amplifier transconductances used in individual integrators. The systematic approach allows the evaluation of different loop filters (order, aggressiveness, discrete-time or continuous-time implementation) with quantizers varying in resolution. Topologies explored range from simple single loops to multiple cascaded loops with complex structures including more feedbacks and feedforwards. For differential circuits, with switched-capacitor integrators for discrete-time (DT) loop filters and active-RC for continuous-time (CT) ones, the passive integrator components are calculated and the power consumption is estimated, based on top-level requirements like harmonic distortion and noise budget.
This unified, systematic approach to choosing the best sigma-delta ADC implementation for a given design target yields an interesting solution for a high-resolution, broadband (DSL-like) ADC operated at low oversampling ratio, which is detailed down to transistor-level schematics.
The target audience of Systematic Design of Sigma-Delta Analog-to-Digital Converters are engineers designing sigma-delta ADCs and/or switched-capacitor and continuous-time filters, both beginners and experienced. It is also intended forstudents/academics involved in sigma-delta and analog CAD research.
