Embodiment Construction

[0044] The present invention will be further described below with reference to 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 description. The operation process of the whole system is divided into many time slots, wherein T={1, . . . , t, . . , |T|} is a set of corresponding time slots. The SDN controller decides the end user's choice of the MEC server, the MEC server decides its own optimal price, and the end user decides the optimal data to be offloaded to the selected MEC server. Under the time slot t, the MEC server s communicates with the SDN controller, where s∈S, S={1,...,s,...|S|}, and the calculation service price is set as and announced to end users. The end user u sends information to the SDN controller, where u∈U, U={1,...,...

Abstract

The invention discloses a dynamic data unloading method and system for mobile edge computing. The method includes: by constructing a two-layer optimization problem model based on the maximization of user benefit function and the maximization of server benefit function, and solving the problem by the two-layer optimization problem model Determine the amount of data offloaded by the end user, the pricing of the server, and the target server where the end user performs data offloading, and the end user offloads the data to the target server. It has the advantages of fully taking care of the rights and interests of both end users and servers, effectively solving the monopoly of one party in edge computing resource transactions, and meeting the diversity of edge computing resource needs.

Description

technical field [0001] The invention relates to the technical field of computer networks, and in particular, to a dynamic data unloading 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 network edge and close to mobile end users. End users can offload their computing tasks to the MEC server, which can further process the tasks offloaded by the user. 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 locally performing computing tasks. Software Defined Network (SDN) has the characteristics of dynamic design, manageability, strong adaptability and high cost-effectiveness, so that MEC systems can greatly benefit from SDN technology. Game Theory is also used to deal with the problem of data offloadin...
