Abstract

In this paper, we designed and implemented ubiquitous u-Health system using RFE and ZigBee. We made a wireless protocol Kit which combines RFE Tag recognition and ZigBee data communication capability. The software is designed and developed on the TinyOS. Wireless communication technologies which hold multi-protocol stacks with RFID and result in the wireless ubiquitous world could be Bluetooth, ZigBee, 802.11x WLAN and so on. The environments that the suggested u-Health system may be used is un-manned nursing, which would be utilized in dense sensor networks such as a hospital. The the size of devices with RFID and ZigBee will be so smaller and smaller as a bracelet, a wrist watch and a ring. The combined wireless RFID-ZigBee system could be applied to applications which requires some actions corresponding to the collected (or sensed) information in WBAN(Wireless Body Area Network) and/or WPAN(Wireless Person Area Network). The proposed ubiquitous u-Health system displays some text-type alert message on LCD which is attached to the system or gives voice alert message to the adequate node users. RFE will be used as various combinations with other wireless technologies for some application-specific purposes.

본 논문에서는 RFID와 근거리 무선 통신 기술인 ZigBee를 접목시켜 유비쿼터스 u-Health 시스템을 구현하였다. RFID 태그인식 기술, ZigBee의 데이터 송수신 기술을 이용하는 무선 프로토콜 키트를 만들었고 TinyOS에서 ZigBee의 소프트웨어를 구현하였다. RFID와 접목 가능한 무선 통신 기술들은 Bluetooth, ZigBee, 802.11x WLAN 등이 있다. 논문에서 제시한 환경은 무인간병과 같은 u-Health 시스템으로서, 조밀한 sensor 네트워크 환경을 갖게 되는 병원 등의 환경에 적합하도록 ZigBee를 사용한 것이다. RFID와 ZigBee가 부착되는 디바이스들은 앞으로 팔찌, 손목시계, 반지 등의 크기로 소형화 될 것이다. 본 논문에서 제안하는 RFID와 ZigBee 통합 환경은 WBAN(Wireless Body Area Network) 및 WPAN(Wireless Person Area Network)환경에서 상태 정보를 인식하여 원하는 action들로 반응하도록 요구되는 응용에 활용될 수 있다. 태그의 정보와 환자의 상태에 따라 여러 가지 제약사항을 두어 환자의 단말기에 문자정보의 형태로 LCD에 표시하거나, 음성정보로 메시지를 전송하도록 설계하고 구축하였다 RFID는 어플리케이션의 목적에 맞춰 다양한 무선통신 기술과의 결합을 이루어 나갈 것이다.
