Abstract

The invention provides a user preference-based dynamic computing migration method and device for a smart city, and the method comprises the steps of initializing a set of input tasks; stipulating an algorithm stop standard, a population maximum iteration frequency, the number of neighborhood vector sets of each particle and a population initial migration strategy, and defining a group of weight vector sets required to be used in the algorithm; then, on the basis of an MOEA / D algorithm, continuously updating a migration strategy of the task by taking optimization of total energy consumption andtotal time delay of the mobile equipment task of the user side from generation to completion as a target; meanwhile, in order to meet the requirements of the user, adding an elitist strategy which can be changed in a directed mode according to the requirements and preferences of the user; according to the invention, an elitist strategy is adopted, energy consumption and time delay generated by task processing are comprehensively considered while user preferences are met, an appropriate calculation migration strategy is formulated for user tasks in an MEC environment, and the purpose of multi-objective optimization is achieved.

Description

technical field

[0001] The present invention relates to the field of computer technology, in particular to a method and device for dynamic computing migration based on user preferences for smart cities. Background technique

[0002] With the introduction and application of emerging concepts such as the Internet of Things and cloud computing, people's lives have undergone earth-shaking changes. At the same time, people's needs have further increased, especially in daily life cities. The result of modernization, get more novel and intelligent high-end services. Therefore, the traditional urban model may not be able to meet people's needs, or it may not be able to adapt to the development of modern society. To this end, people put forward the new concept of smart city, hoping to promote the modernization and intelligentization of the city through emerging information technologies such as the Internet of Things, and combine information technology with specific applications in t...
