Abstract

The invention relates to an unmanned aerial vehicle trajectory optimization and resource allocation method. The method comprises the following steps: S1, modeling an unmanned aerial vehicle trajectoryoptimization and resource allocation problem based on an unmanned aerial vehicle base station system; S2, planning an unmanned aerial vehicle trajectory optimization and resource allocation problem to ensure the fairness of unmanned aerial vehicle service for each user; S3, jointly optimizing the bandwidth and the power of the unmanned aerial vehicle under the condition of giving the track of theunmanned aerial vehicle; S4, optimizing the trajectory of the unmanned aerial vehicle under the condition of given bandwidth and unmanned aerial vehicle power; S5, comprehensively considering the S3and S4, and solving the problems of unmanned aerial vehicle trajectory optimization and resource allocation. According to the invention, the service quality of edge users, users blocked by obstacles and the like can be improved; bandwidth, power distribution and flight path of the unmanned aerial vehicle are optimized at the same time, so that the bandwidth, the power distribution and the flight path of the unmanned aerial vehicle are matched with one another, and communication efficiency of a communication system is greatly improved under limited communication resources.

Description

technical field [0001] The present invention relates to the field of unmanned communication, and more specifically, to a method for optimizing trajectory of an unmanned aerial vehicle and allocating resources. Background technique [0002] Due to its characteristics such as low cost, high mobility, and on-demand deployment, unmanned aerial vehicle (UAV) has been widely used in military and civilian fields, such as search and rescue, inspection, surveillance, and cargo transportation. [0003] In recent years, there are more and more practical applications of UAVs in the field of wireless communication, which has aroused great interest of researchers. Among them, UAVs as base station communication have become a research hotspot in recent years. Compared with traditional fixed-location base stations, drones have natural advantages as base stations. It can use its flexible mobility to achieve rapid on-demand deployment to solve communication problems in signal blind areas that ...
