최근 모바일 RFID 분야는 기존의 RFID 서비스와 이동통신 서비스가 융합하여 사회 전반에 걸쳐서 다양한 연구가 진행되고 있다. 그러나 핵심 소프트웨어인 미들웨어 분야에서 기존의 RFID 미들웨어는 기능이 너무 복잡하여 시스템 자원이 한정되어 있는 모바일 RFID 서비스에는 적합하지 않다. 또한 특히 RFID 미들웨어는 리더에서 발생된 태그 정보를 응용프로그램에게 전달하는 소프트웨어로 많은 글로벌 IT 기업과 연구소에서 연구되고 있다. 그러나 기존의 이러한 미들웨어에 관한 연구는 태그를 식별하기 위한 서비스에 초점이 맞추어져 모바일 RFID 서비스를 위한 미들웨어의 구조로는 적합하지 않다. 본 논문에서는 기존의 RFID 미들웨어의 문제점을 알아보고, 모바일 RFID 서비스에 최적화된 미들웨어의 요구사항을 분석하였다. 그리고 모바일 RFID 미들웨어의 핵심 컴포넌트와 상호간의 인터페이스를 설계하였다.

The most critical element in the real-time operation of RFID application programs that are suitable for the mobile environment is the RFID middleware, made exclusively for mobile handsets, which processes collected data on a real-time basis and sends only the useful information to the application client. In this paper, we intend to design and implement a mobile RFID middleware system that supports the mobile handset environment for real-time based processing of the necessary data in the mobile environment. The proposed mobile RFID middleware system includes a mobile reader interface that collects the tag data, a mobile filtering engine that processes the tag data into more meaningful data that is sent to the application interface, and finally the mobile application interface that supports the m-SOAP application access protocol for interfacing with existing mobile applications. The filtering speed of the newly-developed middleware engine was found to be suitable for the characteristics of mobile handsets.

The most critical element in the real-time operation of RFID application programs that are suitable for the mobile environment is the RFID middleware, made exclusively for mobile handsets, which processes collected data on a real-time basis and sends only the useful information to the application client. In this paper, we intend to design and implement the Pet management system for optimized mobile RFID middleware that supports real-time data processing. The proposed Pet management system consists of registration module, retrieval module, communication module, and display module in order to display retrieval result from server. Also, the captured data in the PDA is transmitted to the server and another client system using the mobile application interface that supports the SOAP application access protocol.

RFID technology is one of the core technologies for ubiquitous computing, and many research activities have been going on in this research area currently. Related with these researches, mobile RFID network services using mobile devices having a built-in RFID reader and mobile networks have been launched in Korea, for the first time in the world. In this paper, we propose a method to coulect ALE middleware suggested by EPCglobal and existing mobile RFID network services. Especially, a RFID code conversion method is proposed to process mobile RFID code systems within ALE middleware systems. Using the proposed method, application developers and(or) content business industries can acquire the information they want, which is filtered and refined in real-time or periodically, from mobile RFID users. So, they can Provide customized services to users by using the user preference information. In this war, the ALE middleware system can be easily extended to process mobile RFID code effectively.

Recently, there has been much research to develope and apply RFID technology, which has a kcy role in the upcoming ubiquitous society, in many fields such as physical distribution, traffic control, medical service, and so on. However, there has been little research on a ubiquitous education or learning including 'u-Campuses' and 'u-Libraries'. Based on the characteristics of RFlD, this paper proposes a system for English learning required in globalization age. RFID tags and sensors utilize wireless communications to track the location and status information of the user to deliver English situated learning services. The current RFID-based system should use quite a different rniddleware, compared with a general-purpose middleware on server or desktop. The RFID system is used on a mobile PDA and consists of essential APIs such as reader and tag control, queue, and filter management.

As ubiquitous computing is evolving, RFID/USN technology is largely applied to various fields. Although there has been much research on the improvement of educational environment using RFID/USN technology, there has been little research on the learning improvement using it. So, in this paper, we used RFID/USN technology to find out the location and situation of students for Chinese situation learning system. We developed a mobile RFID middleware for Chinese situation learning system reflecting Chinese characteristics compared with English on PDA. In USN environment, we designed a USN system, which gets the situation information through a sensor network with sensors and sends them for helping learners study in situation learning. We took a pilot test to a small group for the analysis of the system.

The existing patient monitoring system when the patient want own information. The patient confirm information through the medical institution. But the patient monitoring system based on the U-Healthcare, the patient always confirms own information through the mobile device including rfid reader. The patient need RFID middleware design to provide wanting service when the RFID reader read patient's tag information. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific patient monitoring system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and embodied patient monitoring system that use Qt.

Radio frequencies used by the logistics of RFID in various areas, including research the core of ubiquitous computing. Moreover, RFID and the convergence of mobile terminals RFID research started as a B2B service area, B2C services and the expansion of the zone. B2B2C to in order to provide services ranging from mobile terminals for RFID technology development is needed. We develop middleware for a mobile RFID terminal. It consists of multi-code recognition module, the reader control module, the module code interpretation, and Dispatcher module. We present the implementation of these functions on an emulator.

유비쿼터스의 핵심기술인 RFID(Radio Frequency Identification)가 물류, 유통, 교통, 의료 등 다양한 분야에 적용한 연구가 많이 있어 왔지만, RFID를 교육에 적용한 연구는 미미한 편이다. 이에 본 논문은 RFID/USN 기술을 이용하여 학습자의 위치와 상황을 인지하고 그에 부합하는 중국어 상황 학습 시스템을 제안한다. 영어에 비해 중국어가 가지고 있는 특징을 반영한 RFID 미들웨어는 PDA 기반에서 동작하는 모바일 RFID 미들웨어로 중국어 상황 학습에 적합하도록 개발되었다.
