Abstract

The embodiment of the invention discloses a computing task unloading method and device and a computer readable storage medium. The method includes: respectively calculating the communication time forthe user terminal to unload the calculation task, the task execution time for the user terminal to unload the energy consumption to execute the local calculation task and the task execution time for the local execution energy consumption mobile edge calculation MEC server to execute the unloaded calculation task in the mobile edge calculation environment based on the average energy consumption ofthe user and calculating an average response delay based on the sum of the tasks; establishing a multi-objective optimization model for the average energy consumption of the user and the average response delay of the task; and solving the multi-objective optimization model to obtain a plurality of satisfactory calculation unloading decision schemes. According to the method, the calculation task unloading problem is converted into the multi-objective optimization problem and then solved, a plurality of satisfactory unloading decision schemes are obtained, a decision maker can have more choicesin a rapidly changing network environment, and the method is more favorable for adapting to the requirement of changing at any time.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a computing task offloading method, device and computer-readable storage medium. Background technique [0002] With the continuous expansion of the Internet of Things, the number of smart devices and the amount of data are increasing rapidly, but the hardware technology has been stagnant for a long time, which has led to the embarrassing situation of poor experience quality of most Internet of Things applications. The emergence of Mobile Edge Computing (MEC) technology provides a new solution to alleviate this embarrassing situation. Mobile edge computing can provide devices with more and more powerful resources through computing offloading technology, and achieve the purpose of reducing energy consumption and improving user experience while meeting application delay requirements. [0003] Generally speaking, the offloading decision-making indicators of comp...
