USN and RFID, as new technologies for realization of ubiquitous computing, are closely related with each other technically. Nevertheless, these technologies are recognized as a separate research topic, and there are few researches on technical convergence of the two research areas. In this paper, we propose an efficient processing method of various kinds of sensor data which are used in USN environment to provide efficiency from the view point of not only convergence of USN and RFID technologies but also cost and extensibility. Especially, we propose a method of conversion of various sensor data into EPC data format which can be handled in a RFID middleware. Using the proposed method, RFID middleware systems based on international standard specification can handle not only RFID tag data but also general sensor data efficiently, and various types of ubiquitous application services can be implemented at low cost and in a short time.
