Optimization and Modeling of Optical Emission Spatial Coverage from Underwater Multi-Faceted Optical Base Stations

Compared with point-to-point wireless optical communication systems, multi-faceted Optical Base Stations (OBSs) offer the advantages of supporting multi-user access and achieving omnidirectional dynamic communication. The emission structure of the multi-faceted OBSs, which offer wide beam coverage and ensure uniform distribution of optical signals, is essential for users to receive signals while in motion. This paper presents a modeling method for three-dimensional beam coverage based on the multi-faceted OBS architecture. Additionally, a Multi-Objective Particle Swarm Optimization (MOPSO) algorithm is used to optimize the configuration of the multi-faceted LED array by adjusting the deflection angles of the LED arrays and the emission half-angle of the LEDs at the OBS. These advancements aim to enhance beam coverage performance while also providing technical support for achieving omnidirectional communication in underwater optical wireless networks (UOWN).
