Abstract

A method and apparatus for continuously cover coverage points of high-energy-efficiency unmanned aerial vehicle (UAV) relate to the technical field of UAV. The method comprises: determining target parameters; based on the particle swarm optimization algorithm and the target parameters, the initial coordinate position and the initial allocation strategy are optimized iteratively, and the target coordinate position and the target allocation strategy are obtained after each iteration. After a first number of iterations for iterative optimization of an initial coordinate position and an initial allocation strategy reaches a first preset number of iterations, determining a target coordinate position obtained after iteratively optimizing a first preset number of times as an optimal coordinate position, as the target assignment strategy is determine to be the optimal assignment strategy after iteratively optimize the first preset number of times, the problem that the communication energy efficiency is low when the UAV provide continuous coverage to the users in the target area in the existing method of the UAV air continuous coverage is solved.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a method and device for continuous coverage of coverage points of high-energy-efficiency drones. Background technique [0002] Due to the low cost and high flexibility of UAVs, UAVs have been widely used in military and civilian fields. In the field of communication, since UAVs can avoid the influence of buildings at high altitudes and produce high-quality links visible to ground users, UAVs can be used as air access points to provide communication coverage services for ground users. In addition, in some geological disaster areas such as earthquakes, tsunamis and other areas or hot spots of certain events, the ground communication infrastructure is damaged or does not meet the current coverage requirements of hot spots. Due to the flexibility of UAV aerial base stations and non-ground Dependence, drones as aerial base stations are very suitable for providing emergency network cov...
