Performance Evaluation of a Visible Light Communication System for Indoor Navigation

Abstract

Visible Light Communication using modulated LED lighting infrastructure as transmitters and optical cameras as receivers has a lot of new and useful applications as an alternative way of transmitting data for road traffic signaling, navigation inside large buildings, etc. This paper provides extensive and exhaustive simulations to test the functionality and performances of an indoor navigation system based on Optical Camera Communication developed by the authors, by considering the avoidance of light flickering at the emitter and the real-world capture conditions of smartphone cameras used as receivers. The experimental results show that the proposed system can achieve good decoding results in real-word scenarios, even in the presence of camera frame rate errors and independent on the moment the capturing device starts the decoding process.
