In this experience paper we present a case study in using logic programming in a pervasive computing project in the healthcare domain. An expert system is used to detect healthcare activities in a pervasive hospital environment where positions of people and things are tracked. Based on detected activities an activity-driven computing infrastructure provides computational assistance to healthcar...

Without trust, pervasive devices cannot collaborate effectively, and without collaboration, the pervasive computing vision cannot be made a reality. Distributed trust frameworks may support trust and thus foster collaboration in an hostile pervasive computing environment. Existing frameworks deal with foundational properties of computational trust. We here propose a distributed trust framework ...

Pervasive computing has created a need to profile users of these systems in a way never required in traditional computing. To pursue many of the commonly expected goals of pervasive advertising, we also need rich sources of profile information to build up a model of a user’s identity and so target ads to them more effectively. We present an advertising platform that uses information gleaned fro...

Feature interaction describes a situation where the combination of two or more services that individually perform correctly results in unexpected and possibly adverse behaviour. Such feature interaction issues have first been identified in telecommunication systems and are now beginning to be considered in other distributed software systems. We expect significant feature interaction research in...

With the advancements of computer system and communication technologies, Grid computing can be seen as the popular technology bringing about significant revolution for the next generation distributed computing application. As regards general users, a grid middleware is complex to setup and necessitates a steep learning curve. How to access to the grid system transparently from the point of view...

With the rapid development of information technology, it is inevitable for the distributed mobile computing will evolve to the pervasive computing gradually and whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Furthermore, with the development of SOA, more and more pervasive applications have been compo...

The increasing popularity of wireless technologies and mobile computing devices has enabled new application areas and research. One of these new areas is pervasive systems in urban environments, because urban environments are characterized by high concentration of these technologies and devices. In this paper we will show the process of pervasive system design in urban environments, using as us...

Pervasive Computing integrates numerous, casually accessible and inexpensive mobile devices with traditional distributed systems. The foremost issue of pervasive computing is Context-Awareness. Context-Aware Paradigm for Pervasive Computing Environments (CAPP) is a Service Oriented Architecture (SOA) that enhances smart service discovery in a pervasive environment. Objective of CAPP is to deliv...
