Many sensors providing situation data will be in everywhere under the ubiquitous environment. It requires the current RFID system should be extended to recognize and use situation information from the sensors. We already proposed a new RFID system architecture that is suitable for the coming ubiquitous environment, and basically consists of the key components such as the inference engine, use policy, and definition language. It has four alternatives (types) depending on the role distributions to the components. This paper shows the performance evaluations of the alternatives. Using the research results, we can select a proper RFID system architecture for corresponding ubiquitous application. The contributions of this paper are as follow, providing a new RFID system architecture to recognize, analyze, and utilize the situation information; defining the four alternatives for ubiquitous applications.
