Improving the Hybrid FSO/LI-FI/UWOC Network's

Abstract: Optical wireless communications are an alternative approach to address the challenges in completing the deployment of terrestrial networks to underwater optical wireless communication (UWOC) environments. This study aims to investigate the effectiveness of a free-space optical (FSO) channel system to feed light-fidelity Li-Fi-closed underwater platforms that, in turn, supply the non-line-of-sight (NLOS) link with the proper communications. The FSO link faces the challenge of attenuation due to the surrounding environment, which in turn negatively affects the communication link reaching the end user underwater via Li-Fi underwater platforms according to the proposed scenario. measurements show a strong signal at the receiver, it indicates that the reflection is effective and that the system can successfully transmit information using NLOS methods. Multipath with apt transmit power and NLOS transmission surface incident angle selection achieved ambitious results and sustainable connectivity even in rainy situations surrounding the FSO system.
