Current status of indoor positioning system based on visible light

With the flourishing of wireless information access, indoor positioning is becoming a topic of interest in both academic and industry community. Numerous techniques have been proposed to address this problem under diverse circumstances. Recently, the area of indoor positioning is dominated by three kinds of methodologies, such as range-based positioning, fingerprint-based positioning and inertial positioning. This paper is presented to overview the indoor positioning techniques using visible light based on the range-based positioning. The state-of-the-art research results will be studied. The typical localization mechanisms used in visible light positioning systems are analyzed by evaluation metrics to provide an insight of the systems´ performances.
