Abstract: Disclosed is a geo-networking transmission method of a V2X communication apparatus. The geo-networking transmission method according to an embodiment of the present disclosure includes receiving a geo-networking packet; identifying whether the received geo-networking packet is a packet which is prestored in a buffer; determining whether to perform a forwarding progress of the geo-networking packet, when the received geo-networking packet is not a prestored packet; storing the received geo-networking packet in the buffer and starting a timer, when the forwarding progress is determined; and transmitting the geo-networking packet, when the timer expires.
