New RFID System Architectures Supporting Situation Awareness under Ubiquitous Environments

Abstract

Many sensors providing situation data will be in everywhere under the ubiquitous \nenvironment. The current RFID system should be extended to recognize and use situation information \nfrom the sensors. This study proposes RFID system architectures that are suitable for the ubiquitous \nenvironment. This study applies the situation awareness concept to and extends the current RFID \nsystem architecture to be able to adapt to the environment. The key components include an inference \nengine, use policy and definition language. The proposed architecture is named SA-RFID system \narchitecture and can provides the ability to recognize, analyze and use with situation information from \nsensors under the ubiquitous computing environment. As a result, the usability of the current RFID \nsystem is improved and its application increases.
