Abstract

The invention discloses a method for joint optimization of UAV trajectory, user association and resource allocation. Considering the air-to-air communication network, a patrol system supporting mobile edge computing composed of multiple user UAVs and MEC UAVs, each User drones are equipped with sensors for data collection, and MEC drones are equipped with edge computing servers to assist user drones in computing tasks. User drones move in specified areas to cover mission points, and their computing tasks can be offloaded to the edge. Computing can be performed on the computing UAV, or it can be offloaded to the cluster head UAV for calculation. The trajectory of man-machine is jointly optimized. The present invention can minimize the total energy consumption of the user's UAV under the constraint of ensuring computing resources and task completion time.

Description

technical field [0001] The present invention relates to the technical field of mobile edge computing in UAV Ad Hoc Networks, and specifically relates to a joint optimization method for mobile edge computing UAV trajectory, user association and computing resource allocation under a clustering architecture. Background technique [0002] In the application of area coverage problem, performing computationally intensive tasks is one of the challenges faced by UAVs. In recent years, with the development of communication and artificial intelligence, computing-intensive applications are triggering a mobile application revolution, which can significantly improve the quality of experience of mobile users. However, this poses a great challenge to mobile devices with weak computing power and limited battery capacity. Mobile edge computing is considered as one of the promising technologies to address this challenge, receiving increasing research attention from both industry and academia...
