Abstract

The invention relates to a task offloading device and method supporting mobile edge computing, belonging to the field of wireless communication. The device includes: a terminal characteristic perception module, a task characteristic perception module, an information monitoring module, a network information collection module, an information analysis and processing module, a task offloading decision-making module, and an offloading execution module; The status information is sent to the network information collection module, and the information analysis and processing module comprehensively processes the user terminal characteristics, user task characteristics and candidate MEC server status information, and minimizes task execution under the constraints of meeting the maximum tolerable delay requirements Energy consumption, to achieve the best unloading decision selection. The present invention supports user task offloading based on an optimal offloading strategy in an MEC scenario, and can reduce UE energy consumption and significantly improve user task execution performance.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a task offloading device and method supporting mobile edge computing. Background technique [0002] With the development of mobile Internet and the popularity of smart terminals, new applications such as augmented reality (Augmented Reality, AR), virtual reality and mobile high-definition video continue to emerge. However, the resource-intensive nature of various new applications poses severe challenges to the task processing capabilities of smart terminals. To solve the above problems, Mobile Edge Computing (MEC) technology came into being. This technology deploys MEC servers with strong computing capabilities to the Radio Access Network (RAN), and supports users to offload tasks to MEC servers for calculations, which can effectively reduce terminal task execution delays and energy consumption. Significantly improve user service quality (Quality of Service, QoS). In the ME...

Problems solved by technology

However, the existing research on task offloading schemes supporting MEC seldom considers the design of task offloading devices, which leads to the limitation of the proposed algorithm in practical applications; in addition, how to optimize the selection of offloading servers when there are multiple available MEC candidate servers is also an urgent issue. research questions
