Abstract

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.

RFID 미들웨어는 네트워크를 통하여 다수의 리더로부터 다양한 태그 데이터들을 수집하여 식별정보를 처리한다. 한편, 다양한 유비쿼터스 서비스의 등장으로 대량의 RFID 데이터를 처리할 수 있는 미들웨어가 필요하게 되었다. 본 논문에서는 EPCglobal의 ALE 스펙을 기반으로 구현된 RFID 미들웨어를 이용하여 대량의 RFID 데이터를 가공하고 이를 클라이언트 응용에게 제공하기 위한 방법을 제안한다. 클라이언트의 RFID 데이터 수집 및 가공 처리 요청을 분산하기 위하여, 분산 환경에 구축된 여러 대의 RFID 미들웨어의 자원 정보를 수집하고, 각 RFID 미들웨어의 자원 사항에 따라 클라이언트 요청을 처리한다.
