| Abstract: | Underwater Optical Wireless Communication (UOWC) is a key enabler of the Internet of Underwater Things (IoUT), offering high-speed and low-latency data transmission in aquatic environments. However, system performance is highly sensitive to environmental factors such as absorption, scattering, turbulence, and noise. This study presents a comprehensive, simulation-based performance analysis and optimization of UOWC systems using Opti-System software, focusing on laser diodes operating at 450 nm and 520 nm. Four representative water types—pure seawater, clear ocean, coastal ocean, and turbid harbor—are examined to evaluate key performance metrics, including received power, Q-factor, eye diagrams, signal-to-noise ratio (SNR), bit error rate (BER), and transmission range. An environment-aware optimization framework is proposed, correlating wavelength selection and system configurations with the optical properties of each water type. The impact of transmitter power, beam divergence, photodetector sensitivity, and modulation (OOK) is assessed to identify optimal design choices for robust communication. Simulation results reveal that shorter wavelengths perform better in clearer waters, while adaptive tuning strategies significantly enhance reliability in highly scattering or turbulent conditions. This work provides practical design insights and optimization strategies to support scalable, efficient, and resilient UOWC systems for real-world IoUT applications. [ABSTRACT FROM AUTHOR] |
