Abstract

The invention relates to a collaborative data transmission method in a vehicle networking environment, belonging to the technical field of vehicle networking communication, comprising the following steps: S1: forming a vehicle cluster for assisting downloading; S2: vehicles registering their own information with a roadside unit; The side unit sends a download request and downloads data from it; S4: The next roadside unit coordinates and selects a reverse assist vehicle to download data; S5: The reverse vehicle forwards the downloaded data; S6: The target vehicle receives the data, repeating step S1. The present invention enables the target vehicle to still obtain the required file data in the blind area (Dark Area, DA) of the roadside unit (Road Side Unit, RSU) that is not covered, increases the download data volume of the target vehicle, and increases the data transmission throughput , reducing the impact of data transmission interruption in the blind area, improving the utilization rate of the blind area, and improving the interruption of highway vehicle access to the network.

Description

technical field [0001] The invention belongs to the technical field of vehicle networking communication, and relates to a collaborative data transmission method in a vehicle networking environment. Background technique [0002] As an indispensable part of Intelligent Traffic System (ITS), ICV can complete interactive communication, sensing and computing by equipping with wireless communication equipment, namely On Board Unit (OBU). At the same time, the organic combination of vehicles and roadside facilities through V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure) and other communication technologies will greatly improve travel safety and efficiency. [0003] Resource nodes such as vehicles and roadside units in the network have good data file storage and application data computing capabilities. Compared with vehicle nodes, roadside units have a wider communication range and larger communication bandwidth. Multiple resource nodes within the accommodating coverage a...
