Abstract

The invention discloses a dynamic task unloading method in an uncertain environment in mobile edge computing. According to the invention, the method gives full consideration to the uncertainty of thecloud task queuing waiting time and the randomness and explosiveness generated by massive Internet of Things equipment tasks in an actual distributed Internet of Things environment. According to the method, a buying and selling game model is adopted, a user side is defined as a buyer, a server side is defined as a seller, a multi-stage stochastic programming model is introduced, the uncertainty problem of cloud queuing waiting time delay is solved, efficient task unloading can be carried out in an uncertainty environment, and the success rate of task unloading can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for dynamic task offloading under uncertain environment in mobile edge computing. Background technique [0002] The rapid development and integration of the mobile Internet and the Internet of Things (IoT) has led to an exponential increase in mobile terminal equipment and data traffic. At the same time, emerging applications such as virtual reality / augmented reality, intelligent driving, and intelligent medical care continue to emerge , to further promote the explosive growth of computing-intensive services and applications, and put forward higher requirements for the computing power and battery life of mobile terminals. However, traditional mobile terminals are often limited by size and weight, which still have serious constraints in terms of CPU computing power, battery life, and storage capacity. As an emerging and promising computing paradigm...
