A multicast protocol based on distance is proposed to realize the fast and effective transmission of safety information in the vehicle-borne self-organizing network. The node at the edge of the last hop forwarding node signal is used as the optimal forwarding node to increase the number of new nodes overwritten by the single forwarding. Select the node at the midpoint of the signal coverage and the edge of the secondary proximity signal as an alternative forwarding node to reduce the probability of forwarding failure due to the concealment of the concealed station or the vehicle's departure signal coverage, and transmit the packet recovery route via reverse vehicle storage and forwarding. The simulation results show that the proposed protocol can adapt to the vehicle-density network, meet the requirements of emergency information distribution under different traffic flow densities, reduce the average end-to-end delay and forwarding rate, improve forwarding efficiency, and slow down the broadcast storm.
