This book covers the fundamental principles behind the design of ultra-low power radios and how they can form networks to facilitate a variety of applications within healthcare and environmental monitoring, since they may operate for years off a small battery or even harvest energy from the environment. These radios are distinct from conventional radios in that they must operate with very constrained resources and low overhead. This book provides a thorough discussion of the challenges associated with designing radios with such constrained resources, as well as fundamental design concepts and practical approaches to implementing working designs. Coverage includes integrated circuit design, timing and control considerations, fundamental theory behind low power and time domain operation, and network/communication protocol considerations.

Advanced Computing, Networking and Informatics are three distinct and mutually exclusive disciplines of knowledge with no apparent sharing/overlap among them. However, their convergence is observed in many real world applications, including cyber-security, internet banking, healthcare, sensor networks, cognitive radio, pervasive computing amidst many others. This two volume proceedings explore the combined use of Advanced Computing and Informatics in the next generation wireless networks and security, signal and image processing, ontology and human-computer interfaces (HCI). The two volumes together include 132 scholarly articles, which have been accepted for presentation from over 550 submissions in the Third International Conference on Advanced Computing, Networking and Informatics, 2015, held in Bhubaneswar, India during June 23-25, 2015.

This book proposes representations of multicast rate regions in wireless networks based on the mathematical concept of submodular functions, e.g., the submodular cut model and the polymatroid broadcast model. These models subsume and generalize the graph and hypergraph models. The submodular structure facilitates a dual decomposition approach to network utility maximization problems, which exploits the greedy algorithm for linear programming on submodular polyhedra. This approach yields computationally efficient characterizations of inner and outer bounds on the multicast capacity regions for various classes of wireless networks.

Enterprise Interoperability is the ability of an enterprise or organisation to work with other enterprises or organisations without special effort. It is now recognised that interoperability of systems and thus sharing of information is not sufficient to ensure common understanding between enterprises. Knowledge of information meaning and understanding of how is to be used must also be shared if decision makers distributed between those enterprises in the network want to act consistently and efficiently. Industry's need for Enterprise Interoperability has been one of the significant drivers for research into the Internet of the Future. EI research will embrace and extend contributions from the Internet of Things and the Internet of Services, and will go on to drive the future needs for Internets of People, Processes, and Knowledge.

Space weather has an enormous influence on modern telecommunication systems even though we may not always appreciate it. We shall endeavor throughout this monograph to expose the relationships between space weather factors and the performance (or lack thereof) of telecommunication, navigation, and surveillance systems. Space weather is a rather new term, having found an oMicial expression as the result of several government initiatives that use the term in the title of programs. But it is the logical consequence of the realization that space also has weather, just as the lower atmosphere has weather. While the weather in space will influence space systems that operate in that special environment, it is also true that space weather will influence systems that we understand and use here on terra firma. This brings space weather home as it were. It is not some abstract topic of interest to scientists alone; it is a topic of concern to all of us. I hope to make this clear as the book unfolds. Why have I written this book? First of all, I love the topic. While at the Naval Research Laboratory (NRL), I had the opportunity to do research on many topics including: Thomson scatter radar and satellite beacon studies of the ionosphere, utilization of the NASA Gemini platform for ionospheric investigations, microwave radar propagation studies, I-IF signal intercept and direction-finding experiments, and multi-disciplinary studies of certain physical phenomena relevant to weapon systems development.

This volume contains the proceedings of the IFIP WG 6. 1 International Workshop on Testing of Communicating Systems (lWTCS'96), held in Darmstadt, Germany, on September 9 through II, 1996, continuing the IFIP WG 6. 1 series of International Workshops on Protocol Test Systems (IWPTS). In this series of working conferences, held annually since 1988, many valuable contributions have been presented with an emphasis both on the OSI conformance testing methodology and framework as well as the standardization effort on formal methods in conformance testing. While there are stilI open issues and divergencies between theory and practice in these fields, the scope of the series started expanding to related fields of growing practical relevance, for example to testing with regard to the B-ISDN protocol reference model, in particular ATM, the ODP reference model, and the Internet protocol suite, as well as to interoperability testing and performance testing. To reflect the extended scope, the program committee agreed on a new name for this series of working conferences, to be applied the first time to the 1996 conference. However, in order to emphasize the tradition of IWPTS, the numbering of this series was continued, such that IWTCS'96 is counted as the 9th International Workshop on Testing of Communicating Systems. As in the years before, the workshop aims at bringing together researchers and practi tioners, furthering the exchange of views, and correlating the work of both sides."

The ability to extract generic 3D objects from images is a crucial step towards automation of a variety of problems in cartographic database compilation, industrial inspection and assembly, and autonomous navigation. Many of these problem domains do not have strong constraints on object shape or scene content, presenting serious obstacles for the development of robust object detection and delineation techniques. Geometric Constraints for Object Detection and Delineation addresses these problems with a suite of novel methods and techniques for detecting and delineating generic objects in images of complex scenes, and applies them to the specific task of building detection and delineation from monocular aerial imagery. PIVOT, the fully automated system implementing these techniques, is quantitatively evaluated on 83 images covering 18 test scenes, and compared to three existing systems for building extraction. The results highlight the performance improvements possible with rigorous photogrammetric camera modeling, primitive-based object representations, and geometric constraints derived from their combination. PIVOT's performance illustrates the implications of a clearly articulated set of philosophical principles, taking a significant step towards automatic detection and delineation of 3D objects in real-world environments. Geometric Constraints for Object Detection and Delineation is suitable as a textbook or as a secondary text for a graduate-level course, and as a reference for researchers and practitioners in industry.

Over the last two decades, mobile telecommunications has grown dramatically, from a small niche technology to a massive industry. Mobile telephones are now ubiquitous, and the divisions between PCs, PDAs, mobile telephones and other mobile devices are becoming increasingly blurred. Against this background, the security of information of both the devices themselves, and the information handled by these devices, is becoming ever more important. Security for Mobility pulls together up to the minute research from an international group of academics and professionals working in industry. The main text of the book is divided into five parts - underlying technologies; network security; mobile code issues; application security; and the future. Each chapter of the book is the collaboration of different authors, including many of the leading European experts currently working within the field. Thus each chapter is self-contained and can be read independently, although there are many relationships between the various chapters. The book will be of interest to engineers and computer scientists working in security-related aspects of the communications, computing and telecommunications industries, as well as postgraduate students and academics working within these fields.
