Proposal of Mobile Content Delivery Based on Location Estimation with Active RFID

In this paper, to tackle with uncertainty in the real world, the light-weight ontology drive approach is proposed for the realization of context dependent services. We concentrate on position information and an operation history, as a user's context, and develop our location-aware content delivery system. Through the proofing experiments in Orange Hall, Expo 2005 Aichi and Science Square Tsukuba, our proposed architecture is confirmed to enables us to realize the real world application of context dependency. Finally, we compare our location-aware content delivery system and related researches, and discus the advantage of our system.
