Problems solved by technology

In addition, due to the inconsistency of uplink and downlink bandwidth of the network, network congestion and other factors, the cost of cross-end communication is often asymmetric
Therefore, the current computing task offloading algorithm cannot give an accurate offloading strategy in the actual edge cloud computing model.

Abstract

The invention relates to the technical field of information, in particular to a computing task unloading algorithm based on cost optimization, which mainly comprises the following steps: 1) constructing a new edge cloud computing model; Wherein the new side cloud computing model comprises three important computing costs: the execution cost of a computing task, the communication cost between computing tasks at the same end and the asymmetric communication cost between computing tasks at different ends; (2) expanding a new model of edge cloud computing, (3) merging computing cost, and (4) solving an optimized unloading strategy based on a greedy criterion, and solves the problem of unloading optimization of a computing task in a combined framework of edge computing and cloud computing.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a calculation task unloading algorithm based on cost optimization. Background technique [0002] In edge-cloud computing, that is, the combined framework of edge computing and cloud computing, how to offload tasks from the cloud to the edge is the key to improving the processing efficiency of computing tasks and making full use of the edge-cloud computing framework. Edge devices, such as mobile base stations, mobile phones, and gateways, are close to users, that is, close to data sources. Compared with traditional cloud computing, the data transmission path and transmission time are greatly shortened. But in contrast, the computing power of the edge device is much lower than that of the cloud computing center, so it cannot be determined where the task is performed based on the transmission distance alone. For a batch of tasks, if all the data is offloaded to the edg...
