A Smart User-Centric Visible Light Communication system

This paper presents a smart user-centric visible light communication (VLC) system for indoor communication application wherein the VLC transmitter dynamically changes its location in order to optimize the performance at the receiver end. The experimental set-up of the proposed smart VLC transmitter with barrier detection circuit using micro-controller and ultrasonic sensor is presented. It has been shown that high signal-to-noise ratio (SNR) could be achieved with a fewer light-emitting diodes (LEDs), by using a simple hardware circuitry to get high data rate, irrespective of the location of the user.
