Integrated VLC/RF With Adaptive Power Control for Reliable Cluster-Based VANET Communications by Ahmed M. El-Eraki, Nancy A. Alshaer, Mohamed M. Fouad, Azhar A. Hamdi, Tawfik Ismail

“…Both approaches are evaluated using realistic traffic simulations based on Simulation of Urban Mobility (SUMO) and OpenStreetMap (OSM) data, with a focus on energy efficiency and communication coverage. Simulation results show that DDPA outperforms DFPA in cases with cluster radii below 1159 m, reducing power consumption by up to 20% and serving 90% of vehicles. …”

Performance Analysis of IRS-Assisted Multi-Link FSO System Under Pointing Errors by Takumi Ishida, Chedlia Ben Naila, Hiraku Okada, Masaaki Katayama

“…The integration of intelligent reflecting surfaces (IRS) into free-space optical (FSO) communication systems is considered as a promising and innovative approach to overcoming existing challenges due to the strict line-of-sight (LoS) requirements faced by conventional FSO setups, thereby ensuring more flexible and controllable links and expanding the communication coverage area. Nonetheless, the configuration of IRS-assisted FSO systems remains relatively novel, requiring investigation into optimizing IRS placement to enhance system performance while mitigating interference and obstacles in dynamic environmental conditions. …”
