Semantic Location-Aware Model for Ubiquitous Computing

In order to integrate heterogeneous location-aware systems into ubiquitous computing environment, a novel semantic location-aware model based on ontology is presented. The location-aware model has the capabilities of sharing knowledge, reasoning and adjusting the usage policies of services dynamically through a unified semantic location manner. And a typical conference scenario in ubiquitous computing is taken as an example to demonstrate the feasibility and effective of the semantic location-aware model.
