Internet-of-Vehicles V2I mode task unloading method and system

Abstract

The invention discloses an Internet-of-Vehicles V2I mode task unloading method and system. The method comprises the steps that a vehicle user sends a task unloading request to an MEC server matched with a base station through the base station of a road section where the vehicle user is located; the MEC server receives the task unloading request, unloads the task according to the requirement of thetask unloading request, and calculates a task unloading strategy meeting the time delay based on a game theory method; and the MEC server sends the unloaded task to the base station matched with theMEC server, and the base station transmits the unloaded task to the vehicle user according to the task unloading strategy. According to the task unloading method and system, the MEC server uses a calculation result when a task calculation total overhead target is optimal under a calculation delay limitation condition as a task unloading strategy; and the task unloading strategy is issued through the corresponding communication link, so that the complex operation task processing capability of the Internet of Vehicles is improved to a certain extent, the data processing time delay is reduced, the cost expenditure of task unloading is reduced to the maximum extent, and the service performance of the Internet of Vehicles is improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles communication, and in particular to a method and system for unloading tasks in a V2I mode of the Internet of Vehicles. Background technique [0002] With the massive growth of data services in the Internet of Vehicles, the load of network transmission bandwidth increases and the efficiency of data processing decreases, which leads to the extension of data transmission delay. It is quite fatal for service applications that are sensitive to the delay of the Internet of Vehicles. Effectively processing massive service application data in the Internet of Vehicles is the main way to reduce transmission delay and improve transmission performance. It is closely related to the development of Internet of Vehicles applications. Its technical status has been called the key to measure a country's Internet of Vehicles industry and technological development level. an important symbol. Mob...
