From: Developing hybrid car-to-car communication system based on MIMO visible light and radio frequency
Multi-hop car-to-car communication. Cars VLC communication is either through headlights or tail lights. Then, no communication is possible between neighboring cars. Consequently, the transmitter source (i.e., white car) communicates through the repeater (i.e., blue car) to reach the receiver (i.e., yellow car). Therefore, multi-hop communication forms a chain of repeaters between the source and destination
