Troublesome detectable context-aware services based on game-theory

With rapid progress on ubiquitous technologies, various services become available at anytime and anywhere. One of hot topics in ubiquitous computing is context-aware services, which provide the services at proper time and proper place, in a proper way personalized to a user. However, there may be conflicts of services among users whose contexts are overlapped. Moreover, a context-aware service convenient for a user may cause another user´s unpleasantness even troublesome. In this paper, we consider the relations between contexts of different users. A mechanism consisting of multi-agents, to find and reduce the unpleasantness of users due to context-aware services is constructed based on game-theory.
