A d2d computing offloading method supporting industrial Internet business applications

Abstract

The present invention provides a D2D computing unloading method supporting industrial Internet business applications, including: Step 1: Obtain the distribution status of devices in the Industrial Internet environment; Step 2: Divide Industrial Internet devices into two sets according to the distribution status: available devices Set and target device set; Step 3: Construct a corresponding relay device set to be selected for each target device in the target device set; Step 4: Target device i receives task m i information, and communicate with the devices in the set of relay devices to be selected, and obtain the current bandwidth of all devices in the set of relay devices to be selected, as well as the number of tasks being transmitted; Step 5: Create a calculation offloading model, and use a utility-based method to obtain Generate the final offloading strategy; Step 6: Output the final offloading strategy, including the amount of tasks offloaded to the edge server, the set of relay devices used for offloading, and the amount of data transmitted by each relay device.

Description

technical field [0001] The invention relates to a D2D computing unloading method supporting industrial Internet service applications. Background technique [0002] As one of the core areas of "new infrastructure", the Industrial Internet can connect people, data and machines in the industrial production process, making the industrial production process digital, automated, intelligent and networked, improving production efficiency and reducing production costs. The development of the industrial Internet has also prompted many new industrial applications, such as smart grids and smart transportation, to emerge and become increasingly popular. Using the Industrial Internet, it is possible to carry out automated industrial production, environmental monitoring and urban rescue. However, these applications are usually computing-intensive and sensitive to latency, and most local devices have limited computing capabilities, making it difficult to meet the requirements of these task...

Problems solved by technology

However, the order-based production mode adopted in industrial production will cause the quantity processed by local equipment to change with customer demand, resulting in uncertainty

A large number of orders will lead to a surge in the number of tasks, and the transmission capacity of a single relay device may be difficult to support normal industrial production

Not only that, due to the large number of local devices in the industrial Internet, it is likely that multiple target devices will transmit tasks through the same relay at the same time. At this time, the transmission capability of the relay device will be challenged
