A Ubiquitous Knowledge-based System to Enable RFID Object Discovery in Smart Environments

A ubiquitous Knowledge Base (u-KB) is a distributed and decentralized knowledge base where the factual knowledge (i.e. individuals) is scattered between objects disseminated within a given environment with no centralized coordination. Such a vision enables a truly pervasive environment where autonomous objects set up a self-organized discovery architecture. This paper presents an extended framework to set-up u-KBs. An advanced semantic matchmaking makes possible resource discovery based on metadata stored in RFID (Radio Frequency IDentification) tags without pre-stored and fixed repositories and a dissemination protocol allows an ondemand retrieval of suitable resource descriptions directly from tags located on the objects.
