COMMUNICATION DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

An object of the present invention is to forwards a packet corresponding to trajectories of roads without it being necessary to use road trajectory information. A communication device is mounted on a vehicle. The communication device includes a reception section that receives a packet containing forwarding information that represents a transmission area of the packet that is set up based on a reference direction from a transmission source; an acquisition section that acquires a running direction of its own vehicle; and a processing section that transmits the packet containing the forwarding information to at least the transmission area of the packet that has been set up based on the running direction of its own vehicle,
