Transmission/reception of mobile device for Internet of Things (IoT) in visible light communication

Receiver in existing visible light communication uses LED (light emitting diode) or PD (photodiode). In this paper, android mobile devices without additional devices transmit data via their transmitters, which use only flashlight to send OOK (on-off keying) signals, and their receivers use a camera module that receives binary signals by using light sensitivity. In this paper on android application development technology, we have identified that VLWC (visible light wireless communication) can be performed regardless of place or time, and expect this to be applied to technology development for WPAN (wireless personal area network) among low-power mobile devices in personal activity area.
