  • Emergency message transmission method based on D2D communication in internet of vehicles
    Patent number: 11122401
    Abstract: Disclosed in the invention is an emergency message transmission method based on D2D communication in IoV. Firstly, priority indexes are established for a set of vehicles within a safety range of a certain vehicle, and D2D connection pairs are established in ascending order of the priority indexes to transmit messages; and then, distance prediction is performed on the set of vehicles outside the safety range, priority indexes are established according to predicted distances, and D2D connection pairs are established in ascending order of the priority indexes to transmit messages. If same priority indexes appear, vehicles on the same lane are selected first. The invention implements timely transmission of safety warning information on basis of D2D communication, and performs safety warning, thereby solving the technical problem of inability to transmit safety information in time, and improving transmission performance of traffic messages. Therefore, the invention has high reliability and real-time properties.
