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.

The embodiment of the invention provides a mobile edge data uploading method and system for a vehicle ad hoc network. The method comprises the steps that a vehicle requesting for uploading data sendsa data uploading request to a cluster head vehicle of a vehicle cluster to which the vehicle belongs; the cluster head vehicle receives the data uploading request, determines a target roadside unit responding to the data uploading request from a plurality of roadside units, plans a transmission path between the vehicle requesting to upload data and the target roadside unit, and feeds back the transmission path to the vehicle requesting to upload data; the to-be-uploaded data are divided into a plurality of data segments by the vehicle requesting to upload data according to the number of the vehicles on the transmission path, and each data segment is sent to each vehicle on the transmission path; and each vehicle on the transmission path sends different data segments to the target roadsideunit. According to the invention, each vehicle on the transmission path is used to upload the data to the target roadside unit; the data flow pressure borne by the cluster head vehicle can be reduced;and the data uploading efficiency of the vehicle is improved.
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,...
