Trust Management and Service Selection in Pervasive Computing Environments

Trust is an important aspect of decision making for pervasive applications and it is important to choose and use service efficiently in pervasive computing environments. This paper presents trust force to specify trust among interactive entities in a pervasive computing environment utilizing experience and knowledge in a social network and the Coulomb´s law in real word. Based on trust force, we present a trust management and service selection model, named TMSS. TMSS was tested and the experimental results show that our method for selecting service is not only more efficient than traditional and heuristic methods, but also can isolate malicious services.
