Deploying Visible Light Communication for Alleviating Light Pollution

Abstract

This paper aims at providing a solution to alleviate light pollution using visible light communication (VLC). The motivation behind the work lies in the outrageous expansion of already existing night lights which primarily use light-emitting diodes (LEDs) for illumination. Most of them are not in use simultaneously. We present a futuristic approach in automating these redundant lights. To automate the redundant LEDs, we propose using a wireless feedback mechanism for the received signal-to-noise ratio (SNR) from the user to the LEDs and object localization techniques. Specifically, a reduction of 32% in LED usage for the simulation parameters as per the designed indoor VLC testbed has been observed. Moreover, the developed model can be employed both in indoor and outdoor lighting systems.
