Problems solved by technology

However, the process of unloading user services to the cloud computing center involves multi-hop routing transmission, which not only takes a long time to transmit, but also increases the load on the backhaul link, which cannot effectively meet the needs of delay-sensitive services (such as vehicle network Business, etc.) QoS requirements

Embodiment Construction

[0032] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] This application provides a joint optimization method of computing task offloading and wireless subcarrier allocation based on the sealed auction game model, which can make full use of wireless bandwidth resources and computing resources of each node, thereby effectively solving the problem of wasting wireless bandwidth resources.

[0034] figure 1The queue model of each node in the wireless access network is calculated for the fog in this application. Specifically, the fog computing wireless access network contains three types of nodes, namely user equipment nodes, fog nodes and cloud computing nodes. In this application, consider a scenario where a single cloud computing node serves users in multiple cells in the fog computing wireless access network. ...

Abstract

The invention discloses a computing unloading method in a fog computing wireless network, which comprises the following steps: an FAP broadcasts local queue state information to each user sending a computing unloading request, and each user establishes a bidding function according to the state information of the FAP and submits respective bidding; and the FAP decides the allocation of unloading places and subcarriers of the computing tasks according to the bids of the users. By applying the method, the processing position of the calculation task can be reasonably distributed between the user equipment and the FAP, and the system performance is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a calculation unloading method in a fog computing wireless network. Background technique [0002] With the emergence of a large number of computing-demanding wireless data services, such as virtual reality (VR) services and augmented reality (AR) services, it is difficult for a single user equipment to support related services due to limited computing power and battery capacity. (QoS) requirements. In order to solve the problem of insufficient local computing capabilities, the industry has proposed a solution to introduce a cloud computing center with powerful computing capabilities into the wireless network, and offload a large number of services of user equipment to the cloud computing center for processing. However, the process of unloading user services to the cloud computing center involves multi-hop routing transmission, which not only takes a long t...
