چکیده
Optical wireless communication (OWC) is one of the promising solution to enhance capacity next generation cellular as well fiber-wireless (FiWi) broadband access networks. The proposed work aims complement an OWC system by utilizing unmanned aerial vehicles (UAV) improve performance integrated terrestrial-air-underwater (TAU) framework. Specifically, FiWi based UAV assisted hybrid free-space optical (FSO) and underwater (UWOC) meet high data rate requirement between a terrestrial ground station autonomous vehicle (AUV). scheme compared against conventional radio frequency (RF) TAU We also optimize divergence angle beam FSO link using novel COgnition-based tracking (CODAT) algorithm such that outage probability links minimized AUV satisfied. impact position over-sea surface (OSS) relay altitude on analyzed. Through obtained results it has been shown framework outperforms RF
