초록

LED 조명기구로의 전환은 홈네트워크 등에서 단순히 기계적 연동에 의해 전원제어만이 고려되던 조명기구를 조명과 무선통신이 결합된 하나의 IT 컨버전스(Convergence)로 변환시켰고, 그 구체적인 예가 바로 Visible Light Communication(VLC) 즉 가시광 무선통신이다. VLC의 대표적인 응용으로 고정밀의 실내 위치측정을 기반으로 하는 실내 내비게이션 시스템을 들 수 있다. 본 논문에서는 대형 건물에서 주로 사용되는 형광등 타입의 LED 조명기구와 현재 사용자 단말로 가장 흔하게 사용되는 스마트 기기를 실내 내비게이션 시스템의 구성요소로 고려하는 VLC 기반의 스마트 기기를 이용한 실내 내비게이션 시스템을 모델링하고 구현함으로써 VLC 응용개발의 구현성과 스마트 기기와의 융합성 연구를 보다 용이하게 하고자 한다.

Recently, Light Emitting Diode(LED) light is changing the light equipment, which was considered just as a power-controlled device in home-network, into a IT convergence device by combining illumination function with wireless communication. As a result, Visible Light Communication(VLC) becomes a more practical solution to ubiquitous networks due to the more spread of LED light. One of representative applications using VLC is a VLC-based indoor navigation system which can provide high-accuracy indoor localization. In this paper, we model and implement a VLC based-indoor navigation system in which a fluorescent light type of LED lamp, which is normally used in large buildings, and smart devices, which are usually used by users, are utilized as main components for indoor navigation. Subsequently, it is expected that the paper can contribute to make VLC applications be more active.
