Embodiment Construction

[0015] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] A method for offloading MEC pricing based on D2D communication in the electric power Internet of Things, including the following steps: Step 1, after the inspection equipment completes the data collection work, the tasks in the team are evenly distributed through D2D data communication technology; Step 2, each paired The device determines its own data offloading capacity based on information such as local computing performance, task computing volume, and cloud computing performance; step 3, the MEC server collects the computing power information of all users on the ground, and determines a pricing set based on this information, and sets the price The sets are sorted; step 4, the MEC server broadcasts a pricing plan in the pricing set in order; step 5, the inspection device determines its own uninstallation plan...

Abstract

The invention relates to an MEC pricing unloading method based on D2D communication in the electric power Internet of Things, and belongs to the technical field of mobile communication. According to the technical scheme, in-queue task uniform distribution work is completed through a D2D data communication technology; each pair of paired equipment determines the data unloading amount of the pairedequipment; determining a pricing set, and sorting the pricing set; the MEC server broadcasts one pricing scheme in the pricing set according to the sequence; the inspection equipment determines an unloading scheme of the inspection equipment and uploads the unloading scheme to the MEC server; the cloud server determines the income according to the calculation scheme of the inspection equipment, and judges whether a pricing scheme needs to be updated or not according to an income maximization principle; and the cloud server iteratively outputs an optimal pricing scheme. According to the method,the average calculation time delay of the inspection equipment can be effectively reduced, the MEC server can generate part of benefits, and limited calculation resources of the MEC server are considered, so that the proposed scheme better conforms to the actual scene.

Description

technical field [0001] The invention relates to a D2D communication-based MEC pricing unloading method in the electric power Internet of Things, belonging to the technical field of mobile communication. Background technique [0002] With the development of power Internet of Things technology, substations continue to expand in different regions. The application of handheld inspection equipment can assist inspectors to complete various inspection tasks and improve the efficiency and level of inspection. In addition, in some special climatic conditions and some areas with complex environments, the inspection robot can realize all-weather non-intermittent accurate inspection without being affected by the environment, weather and other factors. However, no matter what kind of inspection equipment, they need to collect a large amount of data during the inspection process. Due to the limited size and battery of the inspection equipment, computing power has become the main factor r...
