The present invention provides a dynamic transmission control method and
system for a floating LoRa network, the method comprising the steps of: presetting an error probability threshold in the LoRa network, calculating a minimum
signal-to-
noise ratio according to the error probability threshold; calculating a first boundary angle according to the minimum
signal-to-
noise ratio, and obtaining a first angle interval; calculating data packet delivery rates and data rates corresponding to different spreading factors and polarization angles, calculating a maximum
throughput, extracting an optimal polarization angle parameter and an optimal
spreading factor parameter according to the maximum
throughput, using the optimal polarization angle parameter as a second boundary angle, and calculating a second angle interval; calculating a transmission period according to the second angle interval, and calculating a data
packet payload transmitted during the transmission period. The present application calculates a maximum
throughput according to the data packet delivery rate and the
data rate, finds a second angle interval, transmits in the second angle interval, improves transmission efficiency, calculates a data
packet payload size according to the second angle interval, and transmits data in the second angle interval, preventing antenna posture from affecting transmission.
