Abstract

According to the complete standard document for PHY/MAC layer of visible light communication through the IEEE 802.15.7 WG on Sept. 2011, visible light communication lays a good foundation for developing a variety of application services. Thus, visible light communication moves to the advanced research period for developing application services, but most of applications are limited only to PtP service model. However, PtMP communication environment for VLC is required to accommodate more various applications. In this paper, we analyze an effect of key parameters on network performance in the star topology based visible personal area network system. We implement a simulator with considering attributes of PHY and MAC layer which are defined by IEEE 802.15.7 standard documents, and analyze the VLC performance.

2011년 9월 IEEE 802.15.7 워킹그룹(Working group)을 통해 LED와 PD를 이용하는 가시광 무선 통신 기술에 대한 물리 계층과 MAC 계층에 대한 표준 규격이 완성됨에 따라 가시광 무선 통신 기술을 이용한 다양한 응용 서비스 기술 개발의 토대가 마련되었다. 이에 따라 가시광 무선 통신 기술은 상용화를 위한 응용 연구 단계로 진입하였으나 대부분의 가시광 무선 통신 환경 개발 현황이 PtP(Peer to peer) 환경을 고려하고 있다. 따라서 보다 다양한 응용 서비스의 개발을 위해서는 PtMP(Point to multi-point) 환경에 대한 연구가 요구된다. 이에 따라 본 논문에서는 IEEE 802.15.7 표준에서 정의한 물리계층과 MAC 계층의 특성을 반영한 스타 토폴로지 기반의 VPAN(Visible personal area network) 시스템 시뮬레이터를 구현하였고, 이를 기반으로 MAC 프로토콜에 영향을 끼치는 주요 파라미터들에 대한 네트워크 성능을 분석하였다.
