Problems solved by technology

A common computing offloading strategy is adaptive offloading based on task characteristics. The task offloading subject adaptively decomposes and offloads its own computing tasks based on factors such as its own computing power, network bandwidth, and the computing power of the offloading object, so as to achieve efficient data processing and Feedback; however, in the actual scenario, in the case of multiple users and multiple edge service nodes, the performance of a single adaptive method is not ideal, so the problem of energy-saving computing offloading for multiple nodes must be solved

Embodiment Construction

[0049] The specific embodiments of the present invention will be described in detail below.

[0050] ①Model definition

[0051] In this project, consider a group of edge service nodes with N={1,2,...,N} side by side, where each node has a computing task to be completed. There are wireless relay devices, such as satellite communication devices, through which edge service nodes can offload computing tasks to the edge service center. Since communication and calculation both play a key role in the calculation offloading process, the communication and calculation models are introduced separately.

[0052] In the communication model, there is a wireless relay device, which manages the uplink and downlink communication of the edge service node, there are M wireless channels, and the group of channels is expressed as M={1,2,...,M}, In addition, we denote {0}∪M as the computing offloading decision of the mobile device user n, if the edge service node n chooses channel a n To uninstall the c...

Abstract

The invention discloses a multi-node computing unloading method. The method is applied to a computing system comprising a group of N = {1, 2,..., N} edge service nodes and an edge service center, theedge service nodes and the edge service center are in communication connection through wireless relay equipment, and the method comprises the following steps: (1) computing a communication model and acomputing model of the edge service nodes; (2) calculating a communication model and a calculation model of the edge service center; (3) performing multi-node unloading game calculation; and (4) making a decision in a Nash equilibrium state of a multi-node calculation task unloading game.

Description

Technical field [0001] The present invention relates to the field of computer technology, and in particular to a multi-node computing offloading method based on game. Background technique [0002] In scenarios such as flood fighting and earthquake relief, it is generally faced with the status quo of destroyed communications and paralyzed infrastructure, making it difficult for on-site units and personnel to obtain stable and reliable information service guarantees. In such scenarios, the information service nodes that can be used such as handheld or backpack-type terminal equipment, drones, command and communication support vehicles have a large number, wide distribution, weak connection, high dynamics, low latency, and high reliability requirements. Features. Due to the ever-changing situation of the site, dangers such as natural disasters, signal interference, or technical failures exist at all times, communication with remote data centers is often limited or even frequently i...
