Claim:
1. A vehicle network transmission method, comprising the steps of: a first transmission device transmitting a data signal to a second transmission device; determining whether the second transmission device is located in a target area; retrieving a geographic location of the first transmission device if the second transmission device is located in the target area; calculating a signal transmission distance of the first transmission device based on an attenuation model of a received signal strength intensity (RSSI) of the second transmission device; and determining whether at least one third transmission device adjacent to the second transmission device in the target area is located in the signal transmission distance; wherein the second transmission device does not continue forwarding the data signal to the at least one third transmission device upon determining that the at least one third transmission device adjacent to the second transmission device in the target area is located in the signal transmission distance of the first transmission device, and the second transmission device determines whether to forward the data signal to the at least one third transmission device based on a distance between the at least one third transmission device and the first transmission device.
