Data forwarding using queues classified for comprehensive infotainment services in VNDN environment including autonomous vehicles, and adaptive data forwarding method and system for services

A method for performing adaptive data forwarding for comprehensive infotainment services by an autonomous vehicle or a road side unit (RSU) in a vehicular named data networking (VNDN) environment including autonomous vehicles, the method comprising:

• generating or receiving a data packet by the autonomous vehicle or road side unit (RSU);
• classifying the data packet according to a class attribute included in the data packet;
• computing a current node weight (CNW) for the data packet including the class attribute from parameters for weight computation, and including the computed weight value into a weight attribute of the data packet;
• determining a forwarding order of the data packet according to the computed current node weight;
• and forwarding the data packet according to the determined order, wherein the parameters for the weight computation include one or more pieces of information among priority, link quality, network density, and arrival time information, and the current node weight is computed by a fuzzy logic system using the parameters for weight computation as input variables.

A system performing 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:
• generating or receiving a data packet;
• placing the data packet, according to a class attribute included in the data packet, into a separate queue classified based on the class attribute;
• computing a current node weight (CNW) for the data packet and including the computed weight value in a weight attribute of the data packet;
• determining a forwarding order of the data packet according to the computed current node weight;
• and forwarding the data packet according to the determined order, and the system further comprising adaptive data forwarding for comprehensive infotainment services in a vehicular named data networking (VNDN) environment including autonomous vehicles.

A computer program stored on a computer-readable non-transitory storage medium for providing data forwarding 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:

• generating or receiving a data packet;
• placing the data packet, according to a class attribute included in the data packet, into a separate queue classified based on the class attribute;
• computing a current node weight (CNW) for the data packet and including the computed weight value in a weight attribute of the data packet;
• determining a forwarding order of the data packet according to the computed current node weight;
• and forwarding the data packet according to the determined order;
• and performing adaptive data forwarding for comprehensive infotainment services in a vehicular named data networking (VNDN) environment including autonomous vehicles.
