A distributed approach for assistive service provision in pervasive environment

In this paper, we propose assistive service provision architecture in pervasive environments. This architecture is based on a distributed approach and ensures service design, deployment and discovery aspects. In order to perform those aspects, several constraints are supported by this architecture such as the context of the pervasive environment, the user profile and the terminal profile. Delivered services are dedicated to dependent people (elderly and people with disabilities). Our strategy is based on our previous work on smart home for people with disabilities. We also present the OSGi-based implementation of our architecture. This implementation is a first step to experiment and validate our approach. We are aiming at having evaluations in real conditions The rapid development of information and communication technologies is opening a large variety of new services and aids not only for valid people, but also for dependent people due to physical/cognitive restriction or the elderly. Combining technical aids and mobile technology allows those people to benefit from an independent living in both usual and temporary living environments.
