Problems solved by technology

However, this invention does not consider the factor of idle devices with fixed addresses when solving the optimal position of the UAV. At the same time, it does not consider the dimension probability in the difference step. When there is strong mobility or there are other edge computing devices in the network, it is difficult to obtain the global optimal solution

Abstract

The invention discloses a UAV-assisted edge computing method considering user mobility, including: establishing a UAV-assisted computing network driven by a digital twin; and using the UAV-assisted computing network to feed back users, UAVs and Real-time data, location and status of idle devices; with the goal of reducing the total user delay, use distributed deep learning to solve the user's unloading strategy; use differential evolution learning to solve the location deployment of drones. The present invention can effectively use the twin network to feed back user real-time data, obtain a global near-optimal solution UAV deployment and unloading strategy, and reduce user processing delay.

Description

technical field [0001] The present invention relates to the technical field of UAV-assisted edge computing, in particular to a UAV-assisted edge computing method considering user mobility. Background technique [0002] In recent years, IoT technology has flourished, providing real-time analytics for smart cities, smart transportation, entertainment management, and more. To support a large number of devices and process massive amounts of data in a timely manner, mobile edge computing supports these latency-sensitive applications by equipping ubiquitous computing resources near mobile user devices. Various research topics, such as task offloading, caching, and resource allocation, are based on the assumption that edge servers have already been placed. The question of how and where to deploy edge servers needs to be addressed. Due to the mobility and dynamic needs of users, current hotspots may cool off soon. To serve time-varying populations, researchers periodically map us...
