Patent ID: 8379611

Claim:
A method of communication between a source node in motion and a destination node, said source and destination nodes belonging to a vehicular network and being adapted to route packets in the network, the method including the following steps executed by a node of the vehicular network: if the node corresponds to the destination node, executing the following steps by said destination node: a step of receiving a packet sent by the source node further including current mobility information relating to the source node; a step of storing said current mobility information relating to the source node; and a step of routing at least one response packet to the source node, comprising: a step of obtaining the stored current mobility information; a step of predicting a location geographical area of the source node from the stored current mobility information relating to the source node the geographical area predicted in this way reputedly being a destination geographical area; and at least one step of sending to the destination geographical area another packet including said response packet and the destination geographical area and, where appropriate, passing in transit through at least one intermediate node of the vehicular network; and if the node corresponds to an intermediate node that is not the destination node, executing the following steps by said intermediate node: a test step during which the intermediate node verifies whether its current position is closer to the destination geographical area than that of a preceding node from which the packet was received, which inserted its current position into said packet before forwarding it; and a step of forwarding the packet in transit to the destination geographical area only if the test is positive.
