The third volume of the influential WWRF Book of Visions of research and trends in mobile communications has been fully updated. It includes three new chapters on flexible spectrum use, ultra-broadband convergent home-area networks, and the system concept. Visions from  manufacturers, network operators, research institutes and academia from all over world are captured by the WWRF in one comprehensive single point of reference. Technologies for the Wireless Future, Volume 3 describes the expectations and requirements of a user in the ‘future wireless world’ between 2010 and 2017. This will enable readers to prioritise research topics based on the provision of cost-effective solutions. This book is ideal for researchers from both academia and industry, as well as engineers, managers, strategists, and regulators.WWRF has become highly influential on the future of wireless communication.  You can see the evidence already, as many of the concepts described in the very first Book of Vision have been adopted in today’s wireless implementations. The organization brings together the long-range views of academia with the practical constraints and requirements of industry.  This is a powerful combination.Mark Pecen, Vice President, Research In Motion LimitedThe WWRF Book of Vision series of books are an invaluable source of information for key thoughts and technology developments in wireless and mobile communication. The comprehensiveness and diversified nature of its research reports and results can prove to be a very useful tool in planning and developing the next generation network and services.Bill Huang, General Manager, China Mobile ResearchAs mobile broadband becomes part of our daily lives, in the same way that mobile telephony has done, and helps us to support important issues such as health care, education and many other priorities, WWRF is again exploring the options for mobile and wireless systems in its' third edition of the Book of Visions. Earlier versions have helped to reach global consensus on research objectives, reduce investment risk and generate critical mass in research efforts. The third book of visions provides key insights into the international academic and commercial discussion on tomorrows' hot topics in mobile research!Håkan Eriksson, Senior Vice President, CTO, Ericsson

Socio-technical Design of Ubiquitous Computing Systems

By using various data inputs, ubiquitous computing systems detect their current usage context, automatically adapt their services to the user’s situational needs and interact with other services or resources in their environment on an ad-hoc basis.Designing such self-adaptive, context-aware knowledge processing systems is, in itself, a formidable challenge. This book presents core findings from the VENUS project at the Interdisciplinary Research Center for Information System Design (ITeG) at Kassel University, where researchers from different fields, such as computer science, information systems, human-computer interaction and law, together seek to find general principles and guidelines for the design of socially aware ubiquitous computing systems. To this end, system usability, user trust in the technology and adherence to privacy laws and regulations were treated as particularly important criteria in the context of socio-technical system design.During the project, a comprehensive blueprint for systematic, interdisciplinary software development was developed, covering the particular functional and non-functional design aspects of ubiquitous computing at the interface between technology and human beings. The organization of the book reflects the structure of the VENUS work program. After an introductory part I, part II provides the groundwork for VENUS by presenting foundational results from all four disciplines involved. Subsequently, part III focuses on methodological research funneling the development activities into a common framework. Part IV then covers the design of the demonstrators that were built in order to develop and evaluate the VENUS method. Finally, part V is dedicated to the evaluation phase to assess the user acceptance of the new approach and applications.The presented findings are especially important for researchers in computer science, information systems, and human-computer interaction, but alsofor everyone working on the acceptance of new technologies in society in general.

Die 16. GI/ITG-Fachtagung Kommunikation in Verteilten Systemen (KiVS 2009) befasst sich als wichtigstes deutschsprachiges Forum für Forschung und Entwicklung auf den Gebieten Kommunikation und Verteilte Systeme mit einer großen Vielfalt von innovativen und zukunftsorientierten Fragestellungen. Sie spannt dabei einen Bogen von allgegenwärtigen verteilten Anwendungen über Middleware-Konzepte und Protokolltechniken bis hin zu modernen Netztechniken mit ihren Mobilitäts- und Sicherheitsfragen. Die KiVS dient der Standortbestimmung aktueller Entwicklungen, der Präsentation laufender Forschungsarbeiten und der Diskussion zukunftsträchtiger Ansätze für die Kommunikation in Verteilten Systemen.
