Abstract Vehicle-to-vehicle (V2V) communication using Li-Fi (Light Fidelity) technology harnesses visible light spectrum from vehicle LEDs for secure, high-bandwidth data exchange, surpassing traditional radio frequency limitations in congested urban environments Objective: The core aim is to create a robust Li-Fi framework for V2V that relays real-time telemetry-vehicle speed, braking status, obstacle detection, and environmental hazards to vehicles within line-of-sight. This supports advanced driver assistance systems, reduces collision probabilities by 30-50%. Novelty: This approach leverages Li-Fi's advantages over RF-based systems, including high data rates, low latency, immunity to electromagnetic interference, and enhanced security through localized light signals, making it ideal for real-time vehicular applications. Methodology: Vehicles are equipped with Li-Fi transceivers using LED headlights/taillights as transmitters and photodetectors as receivers, integrated with microcontrollers like Arduino UNO. Sensors (e.g., ultrasonic, gas) collect data on speed, distance, and hazards, which is encoded, transmitted via visible light, and decoded by nearby vehicles for alerts. Findings: The system enables rapid collision avoidance through real-time data sharing, outperforms RF in speed and reliability, reduces accident risks via immediate hazard detection, and supports applications like traffic condition updates, all validated in simulated dynamic road scenarios.
Keywords Li-Fi, V2V communication, visible light, collision avoidance, enhanced security, real-time data sharing.
