IoT implementation of underwater communication using Li-Fi

Li-Fi is similar to wireless communication which uses the communication medium as light. Nowadays RF interference are getting common due to maximum utility to overcome this problem Li-Fi is introduced in the year 2011. Li-Fi uses LED source to transmit data wirelessly this method is widely called as VLC (visible light communication). IoT technology using light fidelity module plays a vital role in environmental monitoring, underwater disaster management and underwater military applications. Li-Fi communication provides data rate of more than hundreds of Mbps for short ranges and it is an alternative approach to accostic communication in underwater. In Li-Fi, light emitting diode (LED) lamps acts as access points (Aps), and light is used as a medium to carry information bits. At the receiver, a photo diode is employed to collect photons and convert them into a electric current. By using Li-Fi technique, data is transmitted in the light. Photo detector absorbs the light and convert it into electrical signal. The photo detector is placed near the surface of the sea. The information is then passed to cloud storage then it is utilized for various application
