Underwater optical communication and sensing technology in silent ocean

-

KAUST

This dissertation aims to investigate and address noisy ocean issues and build large-scale underwater sensor networks by optical communication and sensing technology. The dissertation proposes using UWOC and FC&S technology to replace the conventional acoustic communication technology and reduce the noise in the ocean. UWOC helps achieve high-speed wireless communications between sensors, vehicles, and even humans for UIoT. The significant challenges of developing UWOC systems are the complex underwater environment's attenuation, scattering, and turbulence effects. This dissertation studied the turbulence effects on the UWOC system’s performance and addressed the pointing-acquisition-and-tracking issues.

Hybrid Acoustic-Pptical strategies for Marine Exploration Sensing

1 min read ·
ISL scientists have developed a hybrid sensor network that overcomes the shortcomings of acoustic and optical waves. Acoustic and optical waves are two of the most commonly used underwater wireless communication systems. The new hybrid sensor network can transmit acoustic and optimal signals simultaneously. This feature alongside other developments makes the sensor network a potential solution for the increased demand in high quality underwater communications. Mohammed Slim-Alouni, a Professor of Electrical Engineering at KAUST believes that using a combination of acoustic and optical waves
