Abstract

The present invention provides a method of service deployment and task offloading based on game theory in edge computing. First, it combines queuing theory to express the request rate and service rate of service requests configured on edge nodes. Secondly, it uses two-stage Stackelberg The lattice game models the interaction between the service provider and the user's service request; finally, the Nash equilibrium is solved by the pruning method, which greatly reduces the time complexity of solving the Nash equilibrium; the beneficial effect of the present invention is: when considering heterogeneous and In the case of resource-constrained edge node service deployment, an optimization scheme for joint service deployment and computing offloading is proposed, which effectively reduces system delay and improves task execution efficiency.

Description

technical field [0001] The present invention relates to the field of edge computing, in particular to a game theory-based service deployment and task offloading method in edge computing. Background technique [0002] In recent years, with the explosive growth of IoT devices and data, people have higher and higher requirements for data services and data transmission rates. And the lack of privacy protection. Although the computing power of the new terminal equipment has been greatly improved, it is not as good as the node and has the limitation of battery capacity. According to the concept of edge computing, mobile devices, as demanders of resources, offload heavy computing tasks to edge nodes, reducing the delay and energy consumption of local processing services. As a computing model complementary to cloud computing, edge computing places computing tasks closer to the data to effectively reduce network transmission delays. Nowadays, more and more applications start to rel...
