Example Embodiment

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] The present invention proposes a joint task scheduling and resource allocation method that supports D2D-edge server offloading. Assuming that users need to perform certain computing tasks, both the mobile edge computing server and the D2D peer user have certain task computing and processing capabilities, and users can use Local execution can also realize task offloading through mobile edge computing servers or D2D peers, modeling user joint overhead as the optimization goal, and realizing joint optimization of user task scheduling, communication resources, and computing resource allocation strategies.

[0028] A method for joint task scheduling and resource allocation that supports D2D-edge server offloading in the present invention assumes that in a network where cellular communication and D2D communication coexist, between two diffe...

Abstract

The invention relates to a joint task scheduling and resource allocation method supporting uninstallation of a D2D-edge server, belonging to the technical field of wireless communication. The method includes the following steps: step 1), modeling a user joint overhead; step 2), modeling a user task execution delay; step 3), modeling user task execution energy consumption; step 4), modeling a usertask scheduling and resource allocation restriction condition; and step 5), determining a user task scheduling and resource allocation strategy based on the minimization of the user joint overhead. According to the scheme of the invention, the minimization of the task execution overhead can be achieved by optimizing and determining the user task scheduling and resource allocation strategy.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a joint task scheduling and resource allocation method supporting D2D-edge server offloading. Background technique [0002] With the rapid development of the mobile Internet and the popularization of smart terminals, applications such as augmented reality (Augment Reality, AR), virtual reality (Virtual Reality, VR) and mobile high-definition video have an increasing demand for Quality of Service (QoS). high. However, the limitations of the processor resources of smart devices and the insufficiency of the traditional mobile cloud computing (Mobile Cloud Computing, MCC) network architecture make the entire network unable to meet the business needs of users to process a large amount of data in a short period of time. In addition, the high power consumption of mobile devices is also Seriously affect the user's service experience (Quality of Experience, QoE). This promo...
