An intelligent user centric middleware for NGN: Infosphere and AmbientGrid
Noëmie Simoni, Chunyang Yin, Ghislain Du Chéné · 2008
In the coming NGN (Next Generation Network) era, a mobile end user desires not only the service accessibility anywhere, but also personalized services adapted to any device, network, and user’s context about location and activity. How to offer optimized user centric services, meanwhile mask the complexity, which is caused by the heterogeneity of the environment and the mobility, becomes our challenge. The goal of our solution is to propose an innovative user centric middleware (Userware) enhancing the seamless feasibility along with the location and activity, personalization and user’s ambient contexts. We propose in this article, first, a decisional knowledge base (Infosphere) managing, in the real time, all the personalization and ambient environment information. An information inference (AmbientGrid) basing on the profiles’ matching, is then proposed to be structured with grid covering the needed user centric environment. We introduce our experimentation and finish the article with a conclusion and perspective.
