VANET, or Vehicle Ad-hoc Network, is a type of network that enables vehicles to communicate with each other and with roadside infrastructure. This communication helps improve road safety, traffic management, and overall driving experience by sharing information about traffic conditions, accidents, and hazards in real-time. In a VANET, vehicles use wireless technology to exchange data, creating a dynamic network that can adapt to changing conditions. This system can enhance navigation, reduce congestion, and support applications like autonomous driving and smart city initiatives, ultimately contributing to safer and more efficient transportation systems.
