This study introduces an innovative approach to facilitate navigation within crowded multi-terminal airports by harnessing Visible Light Communication (VLC) technology. Utilizing existing luminaires as transmission points, encoded messages are conveyed through modulated light signals to offer location-specific guidance to users. Equipped with tetrachromatic LEDs and VLC capabilities, these luminaires efficiently transmit data, as demonstrated through analysis of coverage maps and implementation of the OOK modulation scheme. A novel mesh cellular hybrid structure is proposed, eliminating the need for traditional gateways and enhancing system flexibility. Integrating VLC into Edge/Fog architecture, the system capitalizes on VLC's advantages such as wireless connectivity and secure line-of-sight communication, while leveraging existing lighting infrastructure. This integration enables distributed data processing, storage, and communication at the network edge, thereby improving system performance and responsiveness. The paper presents a detailed airport model generation and analyzes two user categories: pedestrians and luggage/passenger carriers. Users are equipped with PINPIN optical sensors to receive and interpret modulated light signals, facilitating localization and positioning calculations. A communication protocol tailored to VLC specifications is discussed, alongside coding and decoding techniques to ensure reliable transmission. The study conducts a bidirectional communication process to determine optimal paths through the venue, in an airport, employing developed wayfinding algorithms. These algorithms offer turn-by-turn directions, highlight landmarks, alert users about crowded areas, and suggest alternate routes. Using an agent-based simulator, traffic control for both user categories is assessed in various geometric scenarios, with results on user halting and average speed analyzed and discussed. By leveraging VLC and existing luminaires as transmitters, this approach enables indoor navigation independent of GPS signals, typically unavailable indoors. Results demonstrate the system's effectiveness in self-localization, travel direction inference, and route optimization to static or dynamic destinations, ultimately enhancing accessibility and convenience for users in unfamiliar buildings.
