For widespread adoption for the RFID technology, RFID middleware is considered as the key enabler of the RFID evolution while it manages the flow of data between tag readers and enterprise applications and is responsible for the quality, and therefore usability, of the information. In this paper, we introduce the recent researches and developments of RFID middleware and explain the software framework of the RFID middleware which is currently developed in ETRI. In conclusion, our experiences with the current implementation are presented

RFID applied in many area. I think that RFID enlarge for our life more and more. The application technology of RFID change the Mobile RFID using mobile phone and PDF etc. I think, Mobile RFID enlarge application technology gradually. In this paper, we propose the quality measurement metrics for mobile RFID middleware. I propose the quality testing model for interoperability and security of mobile RFID middleware. We examine the international standard for mobile RFID and software testing. In this paper, I proposed the evaluation model of mobile RFID middleware on the basis of international standard ISO/IEC 9126-2 and ISO/IEC 25000 series.

RFID middleware is the system software that converts EPC data collected from RFID reader devices into meaningful data, that users want, and transfers the result to the users with a variety of protocols. ALE specification, the RFID middleware specification proposed by EPCglobal that is a leading group of do facto international standards with respect to RFID, can handle only EPC code. Meanwhile, a new code system which is called KKR was proposed by NIDA in order to represent RFID tag data in a specific manner and cultivate the domestic RFID industry. In this case, the existing RFID middleware can not process KKR code system because of inherent attributes of the system. In this paper, we proposed a method of KKR code conversion to properly process KKR code in ALE middieware, implemented our method in real, and adopted it into existing ALE middleware. Also, we proposed a new URN format for RFID tag data to manipulate KKR code in ALE middleware. By using the proposed method, the existing ALE middleware conforming to international specification can handle KKR code effectively, and the integration among RFID middleware and legacy systems can be easily supported also.

Recently, RFID(Radio Frequency IDentification) has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles : companies have their own operating systems. while RFID is developed regardless of each campany's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system Middle assures that companies adopting RFID system for their logistic service are given athptabwebty to any systems whatsoever, avaweable by way of defining logistic information, tag information and reader information. For this purse, we implement as the basic web service a middleware system that turns all data into XML(eXtensatle Markupmsngunfo) of SOAP(Simple Object Access Protocol), the standard data.

Recently, there is increasing the development requirement of middleware and interface for GPS(Global Positioning System), RFID(Radio Frequency IDentification), sensor networks. GPS supports a useful location based service. RFID supports products logistic and distribution services through the identification. A sensor network collects a context information, such as humidity, temperature and atmospheric pressure. This paper implements and verifies a integrated service middleware for supporting efficiently process of sensing data collected from RFID, GPS and sensor network. This middleware have the temporary store function, the redundancy exclusion function, certification function, the classification function and the database storage function. Additionary, this middleware connects with low-level adaptor using socket interface and supports the high-level application services using database connection. Therefore, user can develop easily various many ubiquitous application system using proposed middleware instead of each RFID middleware, GPS middleware and, middleware based on sensor network.

The field of automatic identification using RF is the one of the emerging ubiquitous computing areas. Early RFID techniques was focused on hardware areas, but RFID middleware has recently gained a lot of attention, which collects and filters tag data, and provides it to enterprise applications. The RFID middleware proposed by EPCglobal only can process EPC tag data, and cannot handle the KKR code which is defined by korean organization. So in this paper, we propose a method which can process the KKR code in RFID middleware systems. Using our approach, the RFID middleware can be extended as general ubiquitous middleware systems which process not only EPC code but also KKR code.

유비쿼터스 환경을 실현하기 위한 핵심 기술로 RFID가 주목받고 있고 많은 연구가 이루어지고 있다. RFID는 점점 소형화되고 주변의 모든 환경 및 사물에 부착 될 것이다. 이러한 환경에서 RFID Tag가 부착된 개체들의 관리와 Middleware의 중요성이 부각되고 많은 기관에서 연구가 진행되고 있다. USN/RFID 환경 하에서 사용하기 위한 Middleware는 다음과 같은 기능이 필요하다. 첫째, RFID가 부착 된 개체가 주위 환경에 민감한 개체일 경우 Middleware에서 자체적으로 상황을 인지하여 대처해야 한다. 둘째, 방대한 양의 raw 데이터 처리를 부하 없이 처리해야 한다. 셋째, 실제 RFID를 적용했을 경우 한 종류의 RFID 장비만을 사용하는 것이 아니므로 다양한 종류의 RFID 장비를 인식할 수 있는 Middleware가 필요하다. 본 논문에서는 RFID에 센서와 무선통신 기술을 결합하여 상황인식(context-aware)이 가능하고, 분산처리 환경을 도입하여 방대한 양의 데이터를 처리 가능하며, 다양한 프로토콜이나 주파수의 장비를 통합적으로 적용 가능한 Middleware의 설계를 제안한다.

An RFID middleware system that can process a large volume of RFID data became necessary with the advent of various kinds of ubiquitous services. In this paper, we propose a method to process massive RFID data and provide it to client applications based on ALE-compliant RFID middleware systems. To distribute the requests to collect and process the RFID data from clients, the proposed system gathers the resource information for RFID middleware systems and processes the requests from clients according to the information.

The development of information technology, which has brought the fusion of broadcasting and telecommunication, wire and wireless communication and voice and data, is developing new fusions like home network which is composed of IT, construction, and home appliances. This trend is considered to continue and to make other new fusions based on previous ones. In this study, we investigate the roles of RFID middleware by identifying the relationships between the new expected fusions and RFID.
