Visible Light Technologies for the Industrial Internet of Things

Sensor networks for the Industrial Internet of Things (IIoT) have become a widespread research topic in recent years, and various technologies have already been proposed and applied for this purpose. The focus of this work is on visible light technologies for localization, sensing, and communication, also known as Visible Light Positioning (VLP), Visible Light Sensing (VLS), and Visible Light Communication (VLC), respectively. The potential of these technologies is discussed with respect to the requirements in sensor networks for IIoT applications (Industry 5.0). Further, an outlook is given on challenges and open topics for future research.
