Internet of Vehicles relay node selection method, device and equipment and readable storage medium

The invention discloses an Internet of Vehicles relay node selection method, which considers that an obstacle exists in the Internet of Vehicles, so that the estimated maximum communication distance of a vehicle is possibly inaccurate, and vehicles beyond the estimated maximum communication distance have the possibility of receiving the broadcast of a sending node, so that the vehicle in the application can receive the broadcast of the sending node after receiving the broadcast of the sending node. When the distance between the vehicle and the sending node belongs to the distance section larger than the estimated maximum communication distance, the vehicle competes with other vehicles in the section to obtain a relay node serving as the sending node, and farther vehicles can be found to serve as the relay node, so that the information transmission efficiency is improved. The invention also discloses an Internet of Vehicles relay node selection device and equipment, and a computer readable storage medium. The
