Embodiment Construction

[0055] Based on layered game, the present invention makes full use of the limited resources of MEC servers that can communicate with each other, aims at minimizing the energy consumption cost of mobile users and maximizing the global revenue of servers respectively at the user layer and server layer, and guarantees the task processing of each mobile terminal real-time. The implementation method of the present invention will be further described below in conjunction with the accompanying drawings.

[0056] as attached figure 1 As shown, it includes mobile users, base stations, APs, MEC servers, and core networks grouped by area. Users connect to different base stations / APs through wireless links, base stations / APs and MEC servers are connected through optical fibers, and resources are shared between servers through wireless communication according to the link status. The MEC server can be deployed inside the base station / AP as a module, or near the base station / AP through a w...

Abstract

The invention discloses a joint resource allocation method based on hierarchical game in a mobile edge computing system, which comprises the following steps: (1) a user terminal establishes a cost function according to different base station / AP access strategies; 2) a base station / AP acquires the connection number of each mobile user terminal in the coverage area and the available resources in thecurrent area, feeds back to the user terminal, the user terminal carries out an evolution game, determines the selection and request resources of the base station / AP, and the base station / AP sends the resource request and the network channel information to the connected MEC server; (3) MEC server shares resources based on complete potential game, establishes utility function, and obtains global optimal solution by using KKT condition; 4) the base station / AP and the MEC server allocate radio resources and compute resources for the current requesting client according to the global optimal solution. The invention is based on a layered game, minimizes the cost of the user terminal and maximizes the revenue of the server layer, prolongs the life of the user terminal, fully utilizes the limitedresources of the MEC server, and meets the task processing requirements of the mobile user.

Description

technical field [0001] The present invention relates to mobile edge computing technology, in particular to a method for joint resource allocation based on layered game in a mobile edge computing system. Background technique [0002] In the 5G heterogeneous network convergence environment, with the widespread popularization of Internet of Things technology and smart mobile terminals, mobile data services such as mobile TV, augmented reality, video calls, and voice chats will bring users a new experience. However, mobile terminals are resource-constrained devices. A wide variety of Internet applications enrich people's daily life while consuming limited terminal device resources, thereby directly reducing people's quality of experience (QoE, Quality of Experience) for application services. . Mobile Cloud Computing (MCC, Mobile Cloud Computing) is the product of the natural combination of mobile Internet technology and cloud computing technology, based on heterogeneous wireles...
