Task unloading method, system and device applied to fog calculation network and medium

Abstract

According to the task unloading method, system and device applied to the fog calculation network and the medium, a task node classifies at least one of a plurality of tasks generated in a plurality ofprevious time slots of the task node into the task node and unloads other tasks to service nodes respectively; obtaining resource occupation information of each task; wherein the resource occupationinformation comprises overhead of each task processed by a node where the task is located, and an unloading decision of each task; estimating the available resource condition of each node in each group according to the acquired resource occupation information; when a new task is generated, according to the estimated available resources of each node in the group, estimating the expenditure requiredfor processing each node of the new task in the group; unloading the task to the node with the minimum estimated overhead; according to the method, the advantages and disadvantages between utilization and exploration are dynamically balanced, and a user is endowed with a task unloading decision intelligently in real time, so that the task unloading problem in the fog calculation network is solvedin an online learning mode.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a task offloading method, system, device and medium applied to a fog computing network. Background technique [0002] With the rapid development of the Internet of Things, the amount of tasks that various mobile smart devices need to handle continues to increase. For example, an online interactive game device using augmented reality technology requires a lot of computing and communication available resources. Therefore, traditional mobile devices such as PCs, smartphones, and IoT devices have encountered great challenges in terms of battery and computing power. Although offloading these computing tasks to cloud servers with abundant energy and computing resources is a solution, long-distance cloud transmission will inevitably lead to additional communication time. In order to meet the service requirements of low latency, researchers propose to use the natural adv...
