A Distributed Base Station Selection Method for UAV Cellular Communication Based on Location Information

Abstract

The invention belongs to the technical field of unmanned aerial vehicle communication, and discloses a method for selecting a distributed base station for unmanned aerial vehicle cellular communication based on location information, including the following steps: S1, building a hybrid base station; S2, building a cellular communication network; S3, unmanned The drone obtains its own longitude, latitude, altitude and timestamp; S4, the UAV sends telemetry frames to the hybrid base station; S5, the hybrid base station calculates the telemetry distance; S6, each hybrid base station floods other hybrid base stations in each time slice Send the distance statistical frame; S7, the mixed base station receives the distance statistical frame and performs sliding window accumulation distance, and marks the active base station; S8, compares each mixed base station with the marked active base station, and marks the current active base station; S9, enters the next time slice Carry out the next round of sliding window cumulative distance. The invention has wide communication range and low use cost; the method of accumulating the distance through the sliding window solves the problem of selecting the most suitable base station for 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 distributed base station for unmanned aerial vehicle cellular communication based on location information. 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 and...
