1. An electronic device, comprising processing circuitry configured to:
determine one or more relay vehicles required to forward a vehicle-related message;
generate the vehicle-related message, wherein the message comprises information about the one or more relay vehicles; and
send the message,
wherein the processing circuitry is further configured to:
determine the one or more relay vehicles based on a real-time topology map in a predetermined range, wherein the real-time topology map comprises real-time position information of all vehicles in the predetermined range;
determine a propagation path of the message;
project vehicles in the real-time topology map onto the propagation path of the message to generate a projection topology map;
determine the one or more relay vehicles based on positions of vehicles in the projection topology map, wherein the real-time topology map further comprises communication quality information of all the vehicles in the predetermined range;
determine the one or more relay vehicles based on the communication quality information of all the vehicles in the predetermined range;
cluster the vehicles in the predetermined range into classes based on the communication quality information;
determine a center of each of the classes;
determine, for each pair of adjacent centers, a midpoint of a line between the pair of adjacent centers; and
determine a vehicle, closest to the midpoint of each pair of the adjacent centers, as the one or more relay vehicles.
