Pervasive Computing and Networking aim at providing ubiquitous, ever-present, adaptable, smart, enveloping and immersive environments in which computing components and humans can interact regardless of the location. The combination of an abundance of computational power of the processors and the communication bandwidth provided by the wireless and mobile networking everywhere and all the time makes such environments within the reach of current technology. Yet, to realize the full potential of such environments, many technical and economical challenges needs to be overcome. These challenges and the perspective on the seminal directions of the research in this area were the subject of the Workshop for Pervasive Computing and Networking at Rensselaer Polytechnic Institute, Troy, NY, USA. This book presents chapters based on presentations made at the workshop by leaders in the field. The scope of Advances in Pervasive Computing and Networking ranges from fundamental theory of pervasive computing and networking to crucial challenges and emerging applications.

Such seminal topics as a scalable, self-organizing technology for sensor networks, the fundamental relationship between the achievable capacity and delay in mobile wireless networks, the role of self-optimization in sensor networks or similarities and differences between computer networks and their biological counterparts are the subject of the first group of chapters.

The next group of chapters covers communication issues, such as cooperative communication in mobile, wireless and sensor networks, methods for maximizing aggregate throughput in 802.11 mesh networks with a physical carrier, and self-configuring location discovery systems for smart environments. The book closes with chapters focusing on sensor network emerging applications such as smart and safe buildings, a design for a distributed transmitter for reachback based on radar signals sensing and two-radio multi-channel clustering.

The unrelenting growth of wireless communications continues to raise new research and development problems that require unprecedented interactions among communication engineers. In particular, specialists in transmission and specialists in networks must often cross each other's boundaries. This is especially true for CDMA, an access technique that is being widely accepted as a system solution for next-generation mobile cellular systems, but it extends to other system aspects as well. Major challenges lie ahead, from the design of physical and radio access to network architecture, resource management, mobility management, and capacity and performance aspects. Several of these aspects are addressed in this volume, the fourth in the edited series on Multiaccess, Mobility and Teletraffic for Wireless Communications. It contains papers selected from MMT'99, the fifth Workshop held on these topics in October 1999 in Venezia, Italy. The focus of this workshop series is on identifying, presenting, and discussing the theoretical and implementation issues critical to the design of wireless communication networks. More specifically, these issues are examined from the viewpoint of the impact each one of them can have on the others. Specific emphasis is given to the evolutionary trends of universal wireless access and software radio. Performance improvements achieved by spectrally efficient codes and smart antennas in experimental GSM testbeds are presented. Several contributions address critical issues regarding multimedia services for Third-Generation Mobile Radio Networks ranging from high rate data transmission with CDMA technology to resource allocation for integrated Voice/WWW traffic.

The author’s main concern is to promote understanding of the basic ideas underlying switching theory. Nothing is taken for granted, whether it is the concept of a logic variable, that of feedback in a latch or sequential circuit, or the necessity to encode internal states. This very basic and thorough approach enables the development of new concepts such as Composition, or Verification. The theoretical side is enhanced by using predicate (instead of propositional) logic allowing for formal proofs till now unattainable. On the practical side, sequential circuits that hitherto were obtained intuitively are now open to a formal synthesis procedure.

The book examines patterns of participation in human rights treaties. International relations theory is divided on what motivates states to participate in treaties, specifically human rights treaties. Instead of examining the specific motivations, this dissertation examines patterns of participation. In doing so, it attempts to match theoretical expectations of state behavior with participation. This book provides significant evidence that there are multiple motivations that lead states to participate in human rights treaties.

This book focus on Long Term Evolution (LTE) and beyond. The chapters describe different aspects of research and development in LTE, LTE-Advanced (4G systems) and LTE-450 MHz such as telecommunications regulatory framework, voice over LTE, link adaptation, power control, interference mitigation mechanisms, performance evaluation for different types of antennas, cognitive mesh network, integration of LTE network and satellite, test environment, power amplifiers and so on. It is useful for researchers in the field of mobile communications.

Asynchronous Transfer Mode (ATM) has revolutionized telecommunications, and has become an integral part of the networking infrastructure.

This introductory well-structured text on ATM networks describes their development, architecture, congestion control, deployment, and signalling in an intuitive, accessible way. It covers extensive background information and includes exercises that support the explanations throughout the book.

The networking expert Harry G. Perros explains ATM networks, including such hot topics as:

• ATM adaptation layer 2

• Quality of Service

• Congestion control

• Tag switching and MPLS (Multi-Protocol Label Switching)

• ADSL-based access networks

• Signalling

• PNNI (Private Network Node Interface)

The research presented in this book discusses how to efficiently retrieve track and trace information for an item of interest that took a certain path through a complex network of manufacturers, wholesalers, retailers, and consumers. To this end, a super-ordinate system called "Discovery Service" is designed that has to handle large amounts of data, high insert-rates, and a high number of queries that are submitted to the discovery service. An example that is used throughout this book is the European pharmaceutical supply chain, which faces the challenge that more and more counterfeit medicinal products are being introduced. Between October and December 2008, more than 34 million fake drug pills were detected at customs control at the borders of the European Union. These fake drugs can put lives in danger as they were supposed to fight cancer, take effect as painkiller or antibiotics, among others. The concepts described in this book can be adopted for supply chain management use cases other than track and trace, such as recall, supply chain optimization, or supply chain analytics.

Operating Systems and Services brings together in one place important contributions and up-to-date research results in this fast moving area. Operating Systems and Services serves as an excellent reference, providing insight into some of the most challenging research issues in the field.

The main purpose of this paper is to contribute to the discussion about the design of computer and communication systems that can aid the management process. 1.1 Historical Overview We propose that Decision Support System can be considered as a design conception conceived within the computer industry to facilitate the use of computer technology in organisations (Keen, 1991). This framework, built during the late 1970s, offers computer and communication technology as support to the decision process which constitutes, in this view, the core of the management process. The DSS framework offers the following capabilities: * Access: ease of use, wide variety of data, analysis and modelling capacity. * Technological: software gel)eration tools. * Development modes: interactive and evolutionary. Within this perspective, computer and communication technologies are seen as an amplification of the human data processing capabilities which limit the decision process. Thus, the human being is understood metaphorically as a data processing machine. Mental processes are associated with the manipulation of symbols aOO human communication to signal transmission.

With the proliferation of ISDN and mobile communication systems, modern commu nication networks are becoming larger-scale, higher-speed, and more complex than ever before. Therefore, besides hardware development, extensive research on system technolo gies with respect to the performance evaluation and management is indispensable for the proper design, development and operation of future complex communication networks. The International Conference on the Performance and Management of Complex Com munication Systems (PMCCN '97) was held from November 17 to 21, 1997, at Tsukuba Science City, Japan. This was the fifth international conference on the performance as pects of communication networks held every three years in Japan (1985 in Tokyo; 1988, 1991, and 1994 in Kyoto). The conference was sponsored by the International Federa tion of Information Processing (IFIP) Working Group (WG) 6.3 Performance of Com munication Systems, and 7.3 Computer System Modelling, University of Tsukuba, Kyoto University, and The Telecommunication Advancement Foundation (TAF)."

Later on the research activities have turned towards the distribution of intelligence in networks and IN applications to multimedia and mobility. The market issues of new services have also been studied. From the system development point of view, topics from OMG and TINA-C have been considered.

Although sophisticated wireless radio technologies make it possible for unlicensed wireless devices to take advantage of un-used broadcast TV spectra, those looking to advance the field have lacked a book that covers cognitive radio in TV white spaces (TVWS). Filling this need, TV White Space Spectrum Technologies: Regulations, Standards and Applications explains how white space technology can be used to enable the additional spectrum access that is so badly needed. Providing a comprehensive overview and analysis of the topics related to TVWS, this forward-looking reference contains contributions from key industry players, standards developers, and researchers from around the world in TV white space, dynamic spectrum access, and cognitive radio fields. It supplies an extensive survey of new technologies, applications, regulations, and open research areas in TVWS. The book is organized in four parts: Regulations and Profiles-Covers regulations, spectrum policies, channelization, and system requirements Standards-Examines TVWS standards efforts in different standard-developing organizations, with emphasis on the IEEE 802.22 wireless network standard Coexistence-Presents coexistence techniques between all potential TVWS standards, technologies, devices, and service providers, with emphasis on the Federal Communications Commission's (FCC) recent regulations and policies, and IEEE 802.19 coexistence study group efforts Important Aspects-Considers spectrum allocation, use cases, and security issues in the TVWS network This complete reference includes coverage of system requirements, collaborative sensing, spectrum sharing, privacy, and interoperability. Suggesting a number of applications that can be deployed to provide new services to users, including broadband Internet applications, the book highlights potential business opportunities and addresses the deployment challenges that are likely to arise.

This book provides unique insight into the use of intranets and extranets. Corporate intranets and the use of internet technology are relatively recent phenomena and the development of these technologies is now fuelling the most significant changes in corporate infrastructure since the development of the PC. The impact is likely to be even greater and is heralding radical changes in the way organizations operate.

"The book provides an introduction to optimization theory and its applications. It is written for senior under-graduate students and first-year graduate students of telecommunication and related fields. Most applications pertain to communication and network problems. Optimization theory involves a great deal of mathematics. The book has practical examples to accompany rigorous discussion so that the reader may develop intuitive understanding on relevant concepts. The materials have been developed from course notes. By attempting to cover convex, linear, and integer optimization for a one-semester course, the author focuses on fundamental concepts and techniques rather than trying to be comprehensive. Infact, the book is written with the main intention to serve as a bridge for students with no prior background in optimization to be able to access more advanced books on the subject later on. "--

The complexity of the UMTS system, new WCDMA technology, and new technical features set new requirements for the radio network planning area. The WCDMA-based UMTS networks need also more advanced and careful radio planning, optimization, and QOS management tasks in order to guarantee seamless mobility and connectivity for the end-user when various voice and data services are used. Hence, new detailed and practical radio planning, optimization, and QOS Management guidelines must be defined through the UMTS planning process. UMTS Radio Network Planning, Optimization and QOS Management describes practical planning process and gives solutions for detailed planning actions by following the planning process. The role of radio planning tool environment is emphasized by specifying the requirements of the digital map production, design tool, field measurement tool, and QOS measurement tool and by giving several examples of the results of these topics. efficient UMTS planning and optimization tool environment and to carry out a practical UMTS planning and optimization project from configuration planning to field and QOS measurements.

Both authors have taught the course of "Distributed Systems" for many years in the respective schools. During the teaching, we feel strongly that "Distributed systems" have evolved from traditional "LAN" based distributed systems towards "Internet based" systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of "distributed systems" with orientation to the requirement of the undergraduate level study for today's distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.

Teleservice is a common concept for distributed application services related to the use of telecommunication equipment, PCs, workstations and mainframes. Teleservices represent a diversity of applications related to various user and vendor cultures such as traditional telecommunications services, E-mail services, cooperative work, applications, multimedia applications, mobile services and intelligent network services. The complexity and diversity of teleservices are increasing, but of greater importance is the change in the way in which teleservices are designed, delivered and maintained. Information Network and Data Communications captures the cultural as well as the technical variety of teleservice.

This book outlines the consequences of digitization for peer-reviewed research articles published in electronic journals. It has often been argued that digitization will revolutionize scientific communication. However, this study shows that this is not the case as far as scientific journals are concerned. Authors make little or no use of the possibilities offered by the digital medium, new procedures for electronic peer review have not replaced traditional peer review, and users do not seem to accept new forms of interaction offered by some electronic journals. The main innovations are to be found at the level of the infrastructures developed by publishers. Scientists themselves appear to be reluctant to change their established patterns of behaviour in formal scientific communication.
