Unmanned aerial vehicle relay deployment method based on multi-detection unmanned aerial vehicle cooperative search

Abstract

The invention discloses an unmanned aerial vehicle relay deployment method based on multi-detection unmanned aerial vehicle cooperative search. The method comprises the following steps: firstly, discretizing time into a time slot form, so that a detection unmanned aerial vehicle can execute a corresponding action in a specific time slot; randomly deploying a plurality of detection unmanned aerialvehicles in the target area, sequentially detecting the network capacity of the current position by each detection unmanned aerial vehicle, interacting the position information and the network capacity information among the detection unmanned aerial vehicles, and updating the positions of the detection unmanned aerial vehicles according to the obtained position information and the obtained networkcapacity information; and finally, performing network capacity detection, information interaction and detection position update iteration circularly until all detection unmanned aerial vehicles converge to the same position, wherein the position is the optimal deployment position. The unmanned aerial vehicle relay deployment can be carried out through real-time capacity detection, and the methodhas the advantages of being easy to operate and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of UAV communication, in particular to a UAV relay deployment method based on multi-detection UAV cooperative search. Background technique [0002] Due to the advantages of low cost and strong flexibility, miniaturized UAVs have been widely used in military and civilian fields, such as patrol monitoring, search and rescue, etc. Assembling communication equipment on UAVs and deploying them in the air to provide communication services for ground users is one of the current research hotspots. UAVs can be flexibly deployed in the air at a height of tens of meters to hundreds of meters. When establishing a link with a ground node, a greater probability of line-of-sight transmission can be obtained, thereby improving communication quality. For example, when the communication distance between the ground user and the base station is too far or is blocked by obstructions, the direct link from the user to the base st...
