Abstract

The invention belongs to the technical field of mobile communication and computers, and particularly relates to a method for computing unloading according to a user moving mode in mobile edge computing. The method comprises the following steps: establishing a communication model of a system in the heterogeneous network; according to the position coordinates of the MEC servers associated with the user in the current time slot and the previous time slot of the user; calculating the distance between the coordinates of the two MEC servers; determining whether the user needs to perform task migration or not; according to the distance between the MEC server coordinates before and after user association, respectively calculating the user experience quality and the delay cost of the user in the moving mode; the difference value between the user experience quality and the delay cost in the mobile mode is used as an award, and the total cost of the user experience quality is optimized by using an improved deep reinforcement learning DQN algorithm; according to the method, a migration unloading decision can be made for the task of the user under the condition that the motion mode of the user is not known in advance, and the method has very strong generalization ability.

Description

technical field [0001] The invention belongs to the field of mobile communication technology and computer technology, and in particular relates to a method for computing unloading according to user task movement patterns in mobile edge computing. Background technique [0002] In recent years, with the maturity of 5G technology and the rapid development of heterogeneous networks based on the Internet of Things, many new applications and new scenarios have emerged. With the exponential growth of mobile smart terminal devices, massive unprocessed data tasks are generated, which puts high demands on the computing power and cache capacity of mobile smart terminal devices. The ability of computing and caching massive data of ordinary household mobile smart terminal devices is difficult to meet the requirements, especially various new technologies gradually emerging in the field of artificial intelligence, such as automatic driving technology, virtual reality technology, augmented ...
