Problems solved by technology
[0003] In the existing vehicle clustering strategy, the cluster head vehicle undertakes the task of uploading data to the roadside unit. Once the load capacity of the cluster head vehicle is insufficient, the data upload efficiency of the member vehicles in the vehicle cluster will be greatly reduced.

Embodiment Construction
[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0061] With the application of the Internet of Things (IoT) in the automotive field, the concept of the Intelligent Transport System (ITS) has gradually emerged, and the Vehicular Ad Hoc Networks (VANET) has become the research field of the Internet of Vehicles. hotspot. Today, when vehicles and roads are equipped with intelligent communication devices, VANET enables users to obtain comprehensive services that are safer, more efficient, comfortable and energy-...

The embodiment of the present invention provides a mobile edge data upload method and system oriented to a vehicle ad hoc network. A vehicle requesting data upload sends a data upload request to the cluster head vehicle of the vehicle cluster to which it belongs; In the side unit, determine the target roadside unit that responds to the data upload request, plan the transmission path between the vehicle that requests to upload data and the target roadside unit, and feed back the transmission path to the vehicle that requests to upload data; the vehicle that requests to upload data according to the transmission path The number of vehicles on the road, divide the data to be uploaded into multiple data segments, and send each data segment to each vehicle on the transmission path; each vehicle on the transmission path sends different data segments to the target roadside unit. By applying the present invention, each vehicle on the transmission path is used to upload data to the target roadside unit, which can reduce the data flow pressure borne by the cluster head vehicle and improve the data upload efficiency of the vehicle.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile edge data upload method and system for vehicle ad hoc network. Background technique [0002] In the case that both the vehicle and the roadside device can be equipped with intelligent communication equipment, the vehicles and the vehicle and the roadside device communicate with each other to form a vehicle ad hoc network (Vehicle Ad Hoc Networks, VANET). At present, in the vehicle ad hoc network, some roadside devices are equipped with mobile edge computing servers to form roadside units. During driving, vehicles will continuously generate some real-time task requests that need to upload data to roadside units for calculation. In order to improve data upload efficiency, vehicles are divided into different vehicle clusters, and only one vehicle in a vehicle cluster can communicate with roadside units. This vehicle is usually called the cluster head vehicle,...
