Unmanned aerial vehicle cellular communication base station selection method based on distributed sliding window counting

Abstract

The invention belongs to the technical field of unmanned aerial vehicle communication, and discloses an unmanned aerial vehicle cellular communication base station selection method based on distributed sliding window counting. The method comprises the following steps: S1, building a hybrid base station; S2, constructing a cellular communication network by using the hybrid base station; S3, the unmanned aerial vehicle sending a telemetry frame to the hybrid base station in the communication range; S4, the hybrid base station counting the number of telemetry frames received in the time slice; S5, each hybrid base station sending a telemetering counting frame in a flooding manner; S6, each hybrid base station receiving the telemetry counting frame for sliding window counting, and marking an active base station of the unmanned aerial vehicle; S7, comparing each hybrid base station with the active base station, and marking the hybrid base station as the current active base station if the hybrid base station and the active base station are the same hybrid base station; and S8, entering the next time slice to carry out next round of sliding window counting. The communication range is wide, and the use cost is low. A sliding window counting mode is utilized to solve the problem of selection of the most suitable base station by the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication, and in particular relates to a method for selecting a base station for unmanned aerial vehicle cellular communication based on distributed sliding window counting. Background technique [0002] With the development of drone technology, drones are no longer simply used in film and television shooting, miniature selfies, etc., in agriculture, logistics, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, etc. There are applications in various fields, and the problem of medium and long-distance UAV measurement and control has also attracted more and more attention. [0003] Due to the limitations of the communication system, ground communication networks (such as 4G, WiFi, etc.) cannot be applied to the field of UAV measurement and control. The channel modes currently used for UAV measurement ...
