최근 통신 기술 및 IT기술을 발전이 급속히 이루어지면서 산업 및 사회 전반에 통신을 빼놓고는 일상 생활을 논할 수 없는 환경이 되었다. 특히 수만은 종류의 모바일 단말들이 널리 보급되면서 언제 어디서나 정보를 접근하고 획득할 수 있는 환경이 구축되어 있으며, 실시간 정보를 들을 접할 수 있는 환경이 조성되었다. 특히 통신 관련 장치가 소형화되고 저전력 기술이 적용되면서, 전에는 접할 수 없었던 특정 사물(컴퓨터, 프린터, 가전, 액츄에이터, 동영상 등)에 대한 네트워크적인 접근이 가능하며, 심지어 각종 센서 정보를 원격을 점검할 수 있게 되었다. 이러한 변화는 실 세계의 사물을 응용 단의 하나의 자원으로 활용할 수 있는 환경이 조성되었으며, 특히 웹 기술을 이용해서 자원을 검색하고 접속/제어하려는 작업이 즉, Web of Things(WoT)개발이 이루어지고 있다. 본 논문에서는 WoT에 대한 개념 및 기술적이슈/표준화적 이슈에 대해서 논한다.
