Abstract: Underwater communication is essential for industries such as marine research, offshore exploration, defense, and telecommunications. Traditional methods, including acoustic and radio waves, suffer from bandwidth limitations, high latency, and interference. Light Fidelity (Li-Fi) technology presents a promising alternative, offering high bandwidth and reduced interference. However, challenges such as signal attenuation, environmental obstacles, and security vulnerabilities must be addressed to ensure reliable and secure communication. This paper proposes a Li-Fi-based underwater communication system that enhances data reliability through deterministic Line-of-Sight transmission and minimal external interference. Security is reinforced using the Advanced Encryption Standard and reliability is ensured through the Cyclic Redundancy Check algorithm. The system successfully transmits various data formats, including text, images, and GIFs. Our findings demonstrate the feasibility of Li-Fi for underwater applications, highlighting its adaptability and potential to overcome existing communication challenges. We aimed to provide a comprehensive understanding of the underlying principles of Li-Fi technology and its adaptability to the challenges posed by underwater communication environments.
