Problems solved by technology

Vehicles have a higher speed relative to the fixed infrastructure, so their link duration is shorter, but the speed difference between two vehicles traveling in the same direction on the same road is much smaller, so the link between vehicles longer duration

Embodiment Construction

[0048] The invention discloses a software-defined car networking computing task migration and scheduling method, including the following steps:

[0049] Step 1, establish a software-defined Internet of Vehicles

[0050] Software-defined car networking includes:

[0051] The data layer includes roadside units, base stations, and vehicles; the data layer unifies roadside units, base stations, and vehicles as an SDN (Software Defined Network, SDN) switch, wherein the roadside units and base stations refer to Facilities deployed on the side of the road for auxiliary communication, directly connected to the wired network, and can communicate wirelessly with the vehicle;

[0052] The control layer, including the SDN controller, is responsible for the orchestration of data layer resources to maintain network topology and status information;

[0053] The application layer includes various services or applications; the services and applications include, for example, augmented reality...

Abstract

A method for migrate and dispatching a software-defined vehicle network computing task When the computational task generated in the vehicle driving process cannot be completed locally in time, the method requests the vehicle to communicate with all the vehicles within the one-hop range of the vehicle, and screens out the task migration execution vehicles according to whether the computational resource is satisfied and whether the task is willing to be executed. Requesting the vehicle to send the IDs of all the task execution vehicles to the controller; The controller establishes and maintainsflow tables for each of the execution vehicles and the requesting vehicle until the requesting vehicle receives the calculation results for each of the execution vehicles. The method also considers the robust computation and communication between the vehicle and the software-defined network controller in the software-defined vehicle networking. When the controller is unable to change the flow entries in the partial vehicle flow tables due to information overload, the agent module of the software-defined network controller in the base station executes instead of the controller.

Description

technical field [0001] The invention relates to the technical fields of software-defined network and Internet of Vehicles, in particular to a method for migrating and scheduling computing tasks of software-defined Internet of Vehicles. Background technique [0002] With the development of intelligent vehicles, the number of automotive electronic products continues to increase, and the scale and complexity of electronic control systems in vehicles increase. Drivers and passengers have higher and higher expectations for intelligent vehicles (including infotainment and communication), and more and more computers The application is implemented in the vehicle environment, and the vehicle resources are limited, unable to process the massive traffic data collected by on-board or roadside sensors, which leads to new challenges, that is, how to meet the computing needs of these in-vehicle applications. Upgrading the on-board computer is an option, but it can be costly. Cloud computi...
