Special Issue Of Ubiquitous Computing And Communication Journal Applied Computing

Routing in Opportunistic Networks focuses on the basics of opportunistic networks, modeling and communication in opportunistic networks, routing in opportunistic networks, and collaboration and cooperation in opportunistic networks. The editors will cover such topics as mobility characterization and discovery in opportunistic networks, scheduling and medium access control in opportunistic networks as well as testbed, tools, and measurements for opportunistic networks.

This special issue draws together some of the contemporary research and development of ubiquitous computing, most of which was foretold by Licklider (1960) and Weiser (1991). Computers are ubiquitous--in terms that they are everywhere--but does this mean the same as ubiquitous computing? The convergent device view posits the computer as a tool through which anything and everything can be done. The divergent device view offers a world where microprocessors are embedded in everything and communicating with one another. This debate is implicitly present in this issue.

With recent advances in radio-frequency identification (RFID) technology, sensor networks, and enhanced Web services, the original World Wide Web is continuing its evolution into what is being called the Web of Things and Services. Such a Web will support an ultimately interactive environment where everyday physical objects such as buildings, sidewalks, and commodities become recognizable, addressable, and even controllable via a mostly ubiquitous Web. This integration of the physical and virtual worlds will fundamentally impact the way we live and in doing so afford tremendous new business opportunities with great human benefit, such as support services to keep the elderly independent, and intelligent traffic management that will cut wasted hours from every day. More efficient supply chains, improved environmental monitoring, better access to health services ... the list is endless. Enabling Context-Aware Web Services: Methods, Architectures, and Technologies compiles the newest developments and advances driving this new age forward. With contributions from leading researchers across the world this pioneering work bridges the gap between context-awareness and Web services. A comprehensive presentation of what’s already accomplished and what is possible, the chapters of this book are systematically organized into three major sections: Methods focuses on the principle of context awareness in Web services and various ways to model those services at the specification level. Architectures details the infrastructures, frameworks, and standards needed to build context-aware Web services. Technologies presents a cornucopia of techniques adapted from once isolated research areas including semantic Web, database, and artificial intelligence development, as well as formal methods being employed to improve the development of context-aware Web services. Researchers, engineers, entrepreneurs, and educators across any number of fields will find new ideas worth considering, jumping-off points for developing improved software and applications, and seeds for business ventures that efficiently deliver needed products, information, or services. The possibilities are as limitless as we dare to imagine.

The International Journal of Advanced Pervasive and Ubiquitous Computing (IJAPUC) is an international refereed research journal integrating the disciplines of pervasive and ubiquitous computing, internet of physical objects, wireless sensor networks, wireless communications, radio frequency identification, automatic identification, real-time localization, information processing, cloud computing, and mass data storage. The journal provides a forum to information technology educators, researchers, and practitioners to advance the practice and understanding of pervasive and ubiquitous computing. The journal features a major emphasis on how to realize pervasive and ubiquitous computing technology and how to build the system in applications. IJAPUC publishes full-length research papers, state-of-the-art reviews, insightful research and practice notes, case studies and book reviews from all areas of pervasive and ubiquitous computing that are selected after a rigorous blind review by experts in the field.

The ?rst IFIP Workshop on Autonomic Communication (WAC 2004) was held 18–19 October 2004 in Berlin, Germany. The workshop was organized by Fra- hofer FOKUS with the help of partners of the EU-funded Autonomic Com- nication Coordination Action — IST-6475 (ACCA), and under technical sp- sorship of IFIP WG6. 6 — Management of Networks and Distributed Systems. The purpose of this workshop was to discuss Autonomic Communication—a new communication paradigm to assist the design of the next-generation n- works. WAC 2004 was explicitly focused on the principles that help to achieve purposeful behavior on top of self-organization (self-management, self-healing, self-awareness, etc. ). The workshop intended to derive these common principles from submissions that study network element’s autonomic behavior exposed by innovative (cross-layer optimized, context-aware, and securely programmable) protocol stack (or its middleware emulations) in its interaction with numerous, often dynamic network groups and communities. The goals were to understand how autonomic behaviors are learned, in?uenced or changed, and how, in turn, these a?ect other elements, groups and the network. The highly interactive and exploratory nature of WAC 2004 de?ned its format — six main sessions grouped in three blocks, each block followed by a panel with all speakers of the previous block as panellists and session chairs as panel moderators.

Panel reports were compiled by panel moderators and conclude this volume.
