Hybrid Architecture for Pervasive Computing Supported Collaborative Work Application and Simulation In this paper we present an hybrid architecture for a computer supported collaborative work in pervasive computing environment simulator. This architecture supports pure simulation mode where all agents are simulated, real deployment where it seamlessly integrates pervasive computing to the computer supported collaborative work and finally an hybrid mode where real devices can interact with simulated ones. This specific architecture provides an original framework to develop and evaluate complex behaviours in pervasive computing environments by allowing scenario to be played in a semi-simulated way and avoid some of the constraints and difficulties of real conditions testing. In addition totheses obvious advantages it also provides a reliable base to capture and analyse real devices behaviour in pervasive computing environments.
