Abstract

In recent years opportunistic computing has gained popularity in Ad-hoc network research area and it is highly required to research for actual services and related requirements. In this paper we summarized a virtual opportunistic service that is named "Children Care System" and proposed an Ad-hoc communication node (uMobile) that is connected with cellular phone and a sensor node (uClo) which is embedding into clothes. uMobile can support cellular phone communication and Ad-hoc communication and uClo can be embedded into clothes and recognize the user status using multiple sensors. In this paper we implemented the location awareness and user status awareness services using uMobile and uClo. We also tested them in indoor situation and showed the result. We expect that our research can play a significant role to inspire another various opportunistic computing services.

최근 Ad-hoc 통신과 관련하여 기회 컴퓨팅(Opportunistic Computing)에 대한 관심이 점차로 커지고 있으며 실질적인 서비스 및 관련된 요구사항에 대한 연구가 크게 요구되고 있다. 본 논문에서는 가상의 기회 컴퓨팅 응용서비스인 "어린이 보호 시스템"에 대해 먼저 논의하고 이 서비스에 적합하도록 새롭게 제작된 사용자용 Ad-hoc 통신 장치인 휴대폰 연동형 노드(uMobile)와 의복내장형 노드(uClo)를 제안한다. uMobile은 휴대폰에 연결되어 휴대폰 통신과 Ad-hoc 통신을 연동할 수 있고 uClo는 다양한 센서를 사용하여 사용자의 상태정보를 인식하며 의복에 내장될 수 있도록 제작되었다. 개발된 통신 장치를 사용하여 위치인식과 상황인지 서비스를 구현하였고 실제 실내 환경에서 테스트하여 그 결과를 나타내었다. 본 연구가 기회 컴퓨팅 기반의 다양한 서비스를 위한 참조 서비스로 활용될 수 있을 것으로 기대한다.
