Method and apparatus for vehicle-to-vehicle multi-hop broadcast communication

The present invention relates to a method and apparatus for reducing the number of packets in a vehicle-to-vehicle multi-hop broadcast communication comprising the steps of: determining a position data comprising a position, a velocity and a direction of a receiving vehicle (1, 2, 3, 4), receiving position data comprising position, velocity and direction from sending vehicles (1,2,3,4), calculating a relative position, a relative velocity and a relative direction between the receiving vehicle (1, 2, 3, 4) and the sending vehicle (1, 2, 3, 4), calculating a density of vehicles from the calculated relative positions, and periodically sending the position data of the receiving vehicle (1, 2, 3, 4), wherein a time for periodically sending the position data of the receiving vehicle (1, 2, 3, 4) is set in accordance with the density of vehicles.
