Design and Analysis of Li-fi Underwater Wireless Communication System

Efficient exploration of techniques for underwater communication is still needed to reduce energy consumption, transmission losses and should also provide high speed communication. This paper presents a simple yet high speed communication system based on visible light communication, also recognised as light fidelity (Li-fi), for underwater applications. The concept of Li-fi for use in underwater wireless communication is borrowed from a novel approach presented by Dr Harald Haas of Germany to improve data transfer and information security for in air applications. This paper presents basic design of a Li-Fi underwater communication system and novel concepts that can help to reduce the overall power consumption. Simulation and comparative study is also given in the paper to provide useful insight of this new technology.
