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.
水下通信对于海洋研究、海上勘探、国防和电信等行业至关重要。包括声波和无线电波在内的传统方法存在带宽限制、高延迟和干扰等问题。光保真（Li-Fi）技术提供了一种很有前景的替代方案，具有高带宽和减少干扰的特点。然而，必须解决诸如信号衰减、环境障碍和安全漏洞等挑战，以确保可靠和安全的通信。本文提出了一种基于Li-Fi的水下通信系统，该系统通过确定性视距传输和最小外部干扰来提高数据可靠性。使用高级加密标准加强安全性，并通过循环冗余校验算法确保可靠性。该系统成功传输了包括文本、图像和GIF在内的各种数据格式。我们的研究结果证明了Li-Fi在水下应用中的可行性，突出了其适应性以及克服现有通信挑战的潜力。我们旨在全面理解Li-Fi技术的基本原理及其对水下通信环境所带来挑战的适应性。
