Policy based management in the pervasive systems

The omnipresence of devices around the user must provide to him useful and relevant services according to its needs. However, each user wants to control how interact with his environment, in particular which services or data he is ready to share with this environment. Consequently, it is necessary to ensure a transparent access to the resources form any point of the pervasive space, to any probably identified and authenticated user and at any moment. Domotic is a pervasive space; Living space of the disabled andor assisted persons is a particular case of domotic. In this paper, we suggest implementing a management and an access control based on policies to ensure the safety in a pervasive space where the information can be privileged andor confidential. According to the obtained results, we adapt our proposition considering living space of the assisted persons where the resources (power of calculate, storage) are limited.
