Pervasive Service Computing: Visions and Challenges

Pervasive Service Computing applies service composition and pervasive computing into managing user's complex everyday activities. To identify the nature of Pervasive Service Computing, we investigate a generic service-oriented pervasive computing scenario - `pervasive campus'. We identify the characteristics of Pervasive Service Computing to be: service-oriented approach, explicit description of user's activity, pervasive nature, semantics, P2P, trust-awareness, and wireless sensor networks. Further, we design a generic computing and communication architecture for Pervasive Service Computing. We specify the challenges facing Pervasive Service Computing, such as context sensing, modeling, reasoning, and P2P-based service composition. Finally, we implement an initial PSC prototype for mobile multimedia service composition.
