Embodiment 1

[0053] Such as figure 2 As shown, the Internet of Vehicles content edge offloading method provided by the embodiment of the present invention includes the following steps: including the following steps:

[0054] Step 1. In the vehicular ad hoc network, due to the high-speed mobility of vehicle nodes, the number and location of resources may change at any time. Therefore, before task offloading, it is necessary to detect resources and filter out available resource information that meets the conditions. ;

[0055] When the client vehicle has a computing task that needs to use the resources of the surrounding vehicles, the resource discovery module first detects the availability of the surrounding vehicles, that is, detects those vehicles that can provide computing resources (resource discovery), and queries the available vehicle node information (vehicle relative position, speed of movement, direction of movement, computing power, etc.).

[0056] Step 2, based on the collecte...

Embodiment 2

[0061] The method for unloading the Internet of Vehicles content edge provided by the embodiment of the present invention is the same as that in Embodiment 1;

[0062] The detection of those vehicles in step 1 that can provide computing resources includes the following:

[0063] The resource discovery module is used to discover available vehicle node computing resources, that is, vehicle node reachability monitoring and resource availability detection, and record the parameters of these nodes, usually recording the computing power, moving speed, moving direction, relative Location.

[0064] Define parameters:

[0065] Computing capability of the vehicle: the computing capability C of the vehicle i ,i=1,2,3..., indicating the number of subtasks that the vehicle can execute per second.

[0066] The moving speed of the vehicle: v i ,i=1,2,3..., the speed of the vehicle.

[0067] The maximum time that vehicles can communicate with each other: T ij , i, j = 1, 2, 3..., that i...

Embodiment 3

[0073] The edge offloading method of Internet of Vehicles content provided by the embodiment of the present invention is the same as Embodiment 1 and Embodiment 2, such as Figure 5 As shown, the task division in step 2 includes the following:

[0074] The task division module divides the task into small subtasks according to the information of available resources, and makes the connection between subtasks as few as possible, strong independence, low coupling and high aggregation. Computational tasks are composed of several subtasks, namely The subtasks are relatively independent, and the size of each subtask is the same, that is, then J 1 =J 2 =…=J i =…=J n , each vehicle node can perform several subtasks according to the amount of computing resources.

Abstract

The invention belongs to the technical field of vehicle-mounted communication, and discloses an Internet of Vehicles content edge unloading method and a mobile resource allocation system. Resource information of a vehicle node is managed, tasks are divided, a target node is combined, and thus, calculation unloading in a vehicular Ad Hoc network is realized; a calculation unloading target node selection method is adopted, in reference to the calculation ability and the time capable of providing service of a node, a corresponding task amount is allocated to the node, and according to the information of each resource, a vehicle is screened. The calculation unloading problem in an interconnection scene between high-mobility vehicles can be solved, and the target of performing calculation at any time and at any place by a user is realized. The resource information of vehicle nodes with high mobility is managed, task dividing and target node selection are combined, and calculation unloadingin the vehicular Ad Hoc network can be realized; and on the basis of comprehensively considering multiple factors, the calculation unloading target node selection method is adopted, and the vehicle isscreened according to the information of each resource.

Description

technical field [0001] The invention belongs to the technical field of vehicle communication, and in particular relates to a method for offloading content at the edge of the Internet of Vehicles and a mobile resource allocation system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the continuous development of Mobile Ad Hoc network technology, vehicular communication has become a new field of research at home and abroad, and Vehicular Ad Hoc Networks (VANETs) have therefore received extensive attention. With the development of computer technology and network technology, there are more and more mobile computing users around the world, and people's life rhythm is getting faster and faster, which makes people's demand for mobile computing higher and higher. Since mobile devices have the characteristics of limited resources, short battery life, and insufficient memory, tasks that require a large amount of ...
