Base station selection method for UAV cellular communication based on distributed sliding window counting

Abstract

The invention belongs to the technical field of UAV communication, and discloses a method for selecting a UAV cellular communication base station based on distributed sliding window counting, comprising the following steps: S1, building a hybrid base station; S2, using the hybrid base station to construct a cellular communication network; S3, the UAV sends telemetry frames to the hybrid base stations within the communication range; S4, the hybrid base stations count the number of telemetry frames received in the time slice; S5, each hybrid base station floods and sends telemetry count frames; S6, each hybrid base station receives telemetry frames The counting frame is counted by sliding window, and the active base station of the drone is marked; S7, each hybrid base station is compared with the active base station, if the two are the same hybrid base station, then the hybrid base station marks itself as the current active base station; S8, enter In the next time slice, the next round of sliding window counting is performed. The invention has wide communication range and low use cost; the problem of selecting the most suitable base station for the unmanned aerial vehicle is solved by using the counting mode of the sliding window.

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 ...
