Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0045] In this embodiment, an MEC system driven by an SDN controller composed of multiple MEC servers and multiple end users is taken as an example for illustration. The running process of the whole system is divided into many time slots, where T={1, . . . , t, . . . , |T|} is a set of corresponding time slots. The SDN controller determines the end user's choice of the MEC server, the MEC server determines its own optimal price, and the end user determines the optimal data offloaded to the selected MEC server. In the time slot t, the MEC server s communicates with the SDN controller, where s∈S, S={1,...,s,...|S|}, and the price of its computing service is set as and announced to end users. The end user u sends information to the SDN controller, where u∈U, U={...

Abstract

The invention discloses a dynamic data unloading method and system for mobile edge computing, and the method comprises the steps: constructing a double-layer optimization problem model based on the maximization of a user benefit function and the maximization of a server benefit function; and solving and determining the data unloading amount of the terminal user, the pricing of the server and a target server for the terminal user to unload the data by the double-layer optimization problem model, and unloading the data to the target server by the terminal user. The method has the advantages that the rights and interests of the terminal user and the server are fully considered, the problem that one party is monopolized in edge computing resource transaction is effectively solved, and the requirement diversity of edge computing resources is met.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a dynamic data offloading method and system for mobile edge computing. Background technique [0002] Mobile Edge Computing (MEC) has become an important solution for providing computing resources at the edge of the network and close to mobile end users. End users can offload their computing tasks to the MEC server, and the MEC server can further process the tasks offloaded by users. The main benefit of MEC technology is the ability to reduce latency, thereby improving the performance of mobile applications, reducing the energy consumption of mobile devices, and reducing the burden of performing computing tasks locally. Software Defined Network (SDN) has the characteristics of dynamic design, manageability, strong adaptability and high cost-effectiveness, so that MEC system can greatly benefit from SDN technology. Game theory (Game Theory) is also used to deal ...
