Abstract

The invention provides a dynamic unloading method of fog calculation based on optimization, belonging to the field of wireless network communication. The present invention divides the calculation request into a local calculation portion and a fog calculation portion. By offloading computationally intensive requests to fog nodes, application performance can be significantly improved. An online joint radio and computational resource algorithm based on Lyapunov optimization is used to derive the upper bound of Lyapunov migration penalty function. By minimizing the upper bound from the perspectiveof different decision variables, , the optimal CPU cycle frequency of local processor is obtained with a convex optimization method. By using the predefined offload priority function, the optimal transmission power of the optimal subchannel is obtained. On the fog node, the optimal request scheduling decision is obtained by absurdity proof.

Description

technical field [0001] The invention relates to the field of wireless network communication, in particular to a Lyapunov optimization-based fog computing dynamic unloading method, which can effectively improve the computing performance of the system. Background technique [0002] Mobile devices have become an integral part of our daily lives as they provide convenient communication almost anywhere anytime. Advanced mobile technologies and high data rate wireless networks are also stimulating the mobile application market. However, the gap between limited computing power and the need to execute complex applications is gradually widening due to resource and battery life constraints. Many computing-intensive and latency-sensitive mobile applications perform poorly on smartphones, such as image processing, board games, etc. [0003] Recent studies have shown that mobile cloud computing technologies offer a promising opportunity to overcome the hardware limitations of mobile de...
