A Smart Submarine Communication for Monitoring Drivers Health and Critical Environment Alert Using Li-Fi

Li-Fi, or Light Fidelity, uses light as a communication medium, falling under the category of Visible Light Communication (VLC). This technology simplifies communication by eliminating the need for cables. Over the years, Li-Fi has proven to be both secure and efficient, achieving high data transmission rates. This research paper examines the fundamental principles of Li-Fi and explores its potential integration into communication systems, covering architecture, modulation techniques, and its advantages and disadvantages. Additionally, the paper demonstrates a communication system where light transmits data between a transmitter and a receiver, controlling the speeds of two motors.
