Management of data sources and services in pervasive environments

Our daily environment contains more and more computerized devices, and tends to become a pervasive environment. Pervasive applications allow the end user to use a large number of heterogeneous devices, potentially invisible to him/her. To manage such kinds of applications, a distributed and modular architecture is required to handle the devices heterogeneity and their dynamicity, concerning their availability as well as the nature of data and services they can provide. In this article, we propose an architecture integrated in our SoCQ project [16] that builds an abstraction of the environment and thus simplifies the development of pervasive applications based on this abstraction. We also detail the current implementation of our architecture that includes the use of the UPnP technology.
