Data forwarding method and system in VNDN environment including autonomous vehicles

A system installed in an autonomous vehicle or a road side unit (RSU) for providing pull-based data forwarding in a vehicular named data networking (VNDN) environment including autonomous vehicles, the system comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions,
• wherein the computer-executable instructions stored in the at least one memory cause the at least one processor to perform:
• (a) a step of generating or receiving a data packet;
• (b) a step of classifying the data packet into critical, non-critical, and entertainment according to a class attribute included in the data packet;
• (c) a step of computing a current node weight (CNW) for the data packet and including the computed weight value in a weight attribute of the data packet;
• (d) a step of determining a forwarding order of the data packet according to the computed current node weight;
• (e) a step of, when the data packet is the packet received in the step (a) and the class attribute of the data packet is entertainment including content requested by another vehicle, comparing the previous node weight (PNW) included in the packet received in the step (a) with the current node weight computed in the step (c), and determining to forward the data packet only when the current weight is greater;
• and
• (f) a step of, when it is determined to forward in the step (e), forwarding the data packet according to the order decided in the step (d), and
• wherein the system further comprises push-based data forwarding for comprehensive infotainment services and push-based data forwarding system in the vehicular named data networking (VNDN) environment including autonomous vehicles.

A computer program stored on a computer-readable non-transitory storage medium for providing pull-based data forwarding for comprehensive infotainment services in a vehicular named data networking (VNDN) environment including autonomous vehicles,

• the computer program being stored on the non-transitory storage medium and including instructions, which cause a processor to execute:
• (a) a step of generating or receiving a data packet;
• (b) a step of classifying the data packet into critical, non-critical, and entertainment according to a class attribute included in the data packet;
• (c) a step of computing a current node weight (CNW) for the data packet and including the computed weight value in a weight attribute of the data packet;
• (d) a step of determining a forwarding order of the data packet according to the computed current node weight;
• (e) a step of, when the data packet is the packet received in the step (a) and the class attribute of the data packet is entertainment including content requested by another vehicle, comparing the previous node weight (PNW) included in the packet received in the step (a) with the current node weight computed in the step (c), and determining to forward the data packet only when the current node weight is greater;
• (f) a step of, when it is determined to forward in the step (e), forwarding the data packet according to the order decided in the step (d);
• and
• (g) performing push-based data forwarding for comprehensive infotainment services in a vehicular named data networking (VNDN) environment including autonomous vehicles.
