vehicular ad-hoc network (automotive) (VANET)

There are currently two approaches for car-to-car(C2C) communications: Wireless Access for Vehicular Environment(WAVE) and Vehicular Ad-hoc Networks (VANET) for real-time communication between vehicles.

While WAVE stands for radio communication of vehicles with roadside facilities, Roadside Units( RSU), or Intelligent Roadside Stations( IRS), Vehicular Ad-hoc Networks (VANET) is about real-time communication between vehicles. It is about improving traffic flow and active safety in Cooperative Adaptive Cruise Control (CACC). Both technologies - WAVE and VANET - are being driven by the Car to Car Communication Consortium( C2C CC) and use 802.11pWLAN technology.

VANET is a type of Mobile Ad-hoc Network (MANET) that supports interaction and real-time communication between vehicles. VANET can be used to exchange status information for traffic safety about the position of vehicles, their driving direction and speed. Participants can assess the current traffic situation and send out alerts in the event of a defect or accident.

In addition to the classic VANET, there is also the InVANET, which is an ad hoc network equipped with artificial intelligence and influences the driving behavior of the motor vehicle in the event of an accident, drunkenness or health-related misconduct.
