Abstract
The invention relates to a method for relaying an item of useful data by way of a transit station (SR), the item of useful data passing via the transit station from a first station (S1) to a second station (S2), wherein a station is a vehicle, a road infrastructure or a personal device of a pedestrian.
Claims13
A method for relaying an item of useful data by way of a transit station, the item of useful data passing through the transit station from a first station to a second station, each of said stations being a vehicle, a road infrastructure, or a personal device of a pedestrian, the method comprising the steps, implemented by the transit station, of:
- receiving from the first station and by means of a short-range network based on multi-hop geographic routing a geo-network packet, the geo-network packet comprising the item of useful data and being configured to be routed by the multi-hop geographic routing of the short-range network;
- processing the geo-network packet in order to generate a cellular packet, the cellular packet comprising the item of useful data and being configured to be routed by cellular routing via at least one base station within a cellular network, the processing being implemented by a layer that is lower than or equal to the network layer;
- transmitting the cellular packet to the second station via the cellular network.
A method for relaying an item of useful data by way of a transit station, the item of useful data passing through the transit station from a first station to a second station, each of said stations being a vehicle, a road infrastructure, or a personal device of a pedestrian, the method comprising the steps, implemented by the transit station, of:
- receiving from the first station and by means of a cellular network (62) based on cellular routing via at least one base station a cellular packet, the cellular packet comprising the item of useful data and being configured to be routed by cellular routing within the cellular network;
- processing the cellular packet in order to generate a geo-network packet, the geo-network packet comprising the item of useful data and being configured to be routed by multi-hop geographic routing on a short-range network, the processing being implemented by a layer that is lower than or equal to the network layer;
- transmitting the geo-network packet to the second station via the short-range network.
A device for relaying an item of useful data that is connected to a transit station, the item of useful data passing through the transit station from a first station to a second station, each of said stations being a vehicle, a road infrastructure, or a personal device of a pedestrian, the device comprising at least one processor and one memory designed to perform the operations of:
- receiving from the first station and by means of a short-range network (54) based on multi-hop geographic routing a geo-network packet, the geo-network packet comprising the item of useful data and being configured to be routed by the multi-hop geographic routing of the short-range network;
- processing the geo-network packet in order to generate a packet, called a cellular packet, the cellular packet comprising the item of useful data and being configured to be routed by cellular routing via at least one base station within a cellular network (62), the processing being implemented by a layer that is lower than or equal to the network layer;
- transmitting the cellular packet to the second station via the cellular network.
A device for relaying an item of useful data that is connected to a transit station, the item of useful data passing through the transit station from a first station to a second station, each said station being a vehicle, a road infrastructure, or a personal device of a pedestrian, the device comprising at least one processor and one memory designed to perform the operations of:
- receiving from the first station and by means of a cellular network (62) based on cellular routing via at least one base station a packet a cellular packet, the cellular packet comprising the item of useful data and being configured to be routed by cellular routing within the cellular network;
- processing the cellular packet in order to generate a geo-network packet, the geo-network packet comprising the item of useful data and being configured to be routed by multi-hop geographic routing on a short-range network (54), the processing being implemented by a layer that is lower than (50, 52) or equal (48) to the network layer;
- transmitting the geo-network packet to the second station via the short-range network.
