Embodiment Construction
[0020] 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.
[0021] Such as figure 1 As shown, the present invention is based on a vehicle networking system composed of multiple base stations (cells) and multiple MEC servers. When a vehicle is driving on the road, there will be multiple base stations and MEC servers around it. There are many potential connection. When the vehicle has a task generated, the vehicle can choose to perform local execution, or it can choose to offload to the most relevant MEC server for remo...

The present invention relates to the technical field of wireless short-distance communication in the Internet of Vehicles system, and in particular to a resource allocation method for the Internet of Vehicles based on MEC multi-server; The system benefit function of vehicle user task execution; each optimization function is simplified by decoupling, and the optimal unloading strategy of the vehicle user is obtained through the multi-round combination unloading scheduling mechanism and the joint resource allocation strategy. When implementing the optimal unloading strategy, multiple MEC The transmission power and computing resources in the server scenario are used to allocate the Internet of Vehicles resources; the present invention determines the resource allocation of the Internet of Vehicles in the MEC multi-server scenario from two aspects of task offloading and resource allocation, and uses a multi-round combined unloading scheduling mechanism and joint resource allocation The strategy is used to solve the problem of task offloading, which reduces the complexity of time, maximizes the average system revenue, and improves the overall performance of the system.
Description
technical field [0001] The present invention relates to the technical field of wireless short-distance communication in an Internet of Vehicles system, in particular to a resource allocation method for an Internet of Vehicles based on an MEC multi-server. Background technique [0002] As the most promising application in the Internet of Things, the Internet of Vehicles has attracted widespread attention from academia and industry. In-vehicle communication can not only improve the safety of the road but also greatly improve the traffic efficiency. It is the most potential development and application in the intelligent transportation system. Vehicle request tasks require frequent access to the Internet or remote servers, involving a large amount of data exchange. V2I communication in the Internet of Vehicles link can provide high-quality services for such tasks. However, with the rapid growth of mobile applications and the Internet of Things, communication technologies impose...
