A Pervasive Computing Environment Based on SIP

Pervasive computing environment represents a mobile and distributed environment. This brings the challenges for user/device mobility, context awareness, services management and invocation. In this paper, we propose a prototype of pervasive computing environment based on SIP to provide solutions of these challenges and to bring the vision into reality. The architecture of FULL is divided into four layers: network layer, service layer, middleware layer and application layer. The structure and implementation of these four layers are described in detail. Finally, a comparison to other projects is given.
