- Abstract
Visible light communication (VLC) can be a promising alternative to radio-based communication for underwater applications. However, VLC suffers from limited range and coverage due to the absorption and scattering of light in water. The purpose of this research is to construct and assess a VLC's performance in turbid, turbulence, and typical ocean water. Utilizing Optisystem simulation software, we design and optimize a hybrid VLC underwater communication system, where a ship can communicate from water surface to inside and internal link between two submarines. The system's performance is measured in terms of bit error rate, data rate, and range under various water conditions, including turbid, normal ocean water, and turbulence water. Instead of implementing higher order modulation or achieving high data rates, the emphasis was on maximizing the simplicity of underwater light communication (ULC) in a variety of weather conditions. We observed BER 5.84x10-9 in the clear water within 500m and BER was 2.8x10-4 in the turbulence water by using OOK modulation scheme. Moreover, this system can transmit data maximum 500m in clear water 230m, and 210 m in turbid and turbulence water simultaneously. By systematically evaluating system performance under various types of water conditions, this model has the potential of effective communication solutions for underwater applications, with implications for various sectors including marine exploration, underwater surveillance, and environmental monitoring.
