| titleOfInvention | A dynamic transmission control method and system for a floating LoRa network |
| abstract | The invention provides a dynamic transmission control method and system for a floating LoRa network. The method includes 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 , obtain the first angle interval; calculate the packet delivery rate and data rate corresponding to different frequency extension factors and polarization angles, calculate the maximum throughput, and extract the optimal polarization angle parameter and optimal frequency extension factor according to the maximum throughput parameter, the optimal polarization angle parameter is used as the second boundary angle, and the second angle interval is calculated; the transmission period is calculated according to the second angle interval, and the payload of the data packet transmitted in the transmission period is calculated. The application calculates the maximum throughput according to the data packet delivery rate and the data rate, finds out the second angle interval, transmits in the second angle interval, improves the transmission efficiency, calculates the payload size of the data packet according to the second angle interval, and the data is in the second angle interval. Two-angle interval transmission to prevent the antenna attitude from affecting the transmission. |
