Ontology-Based RFID System Model for Supporting Semantic Consistency in Ubiquitous Environment

The emerging ubiquitous computing is changing the current computing paradigm, and lets the ubiquitous RFID applications consistently and independently utilize the sensed information from the intelligent and powerful tags which are in a variety of applications fields. One of the most important issues is how to support the semantic consistency between data from various tags in different RFID applications under ubiquitous environment. This paper proposes a new RFID model to resolve the issue and to support the application-independent semantic maintenance in the ubiquitous computing environment based on WordNet, a widely used ontology. Our noble RFID model provides an infrastructure support for the semantic consistency and enables the RFID application-independent informat
