Design of a CRC32 Supported LoRa Communication Protocol and Test

In wireless communication networks, transmitted data may be compromised by many external causes. Such inaccuracies may result in adverse outcomes, particularly in essential applications. LoRa modulation is extensively utilized in industrial and commercial applications. Nevertheless, supplementary error control measures are necessary to guarantee dependable data transfer. This study devised an error detection and retransmission technique to guarantee the integrity of data transmitted in LoRa-based wireless communication systems. Furthermore, the transmitter was equipped to ascertain the presence and activity of the receiver. Test hardware and software algorithms were designed and operated as part of the investigation. In the proposed system, the transmitter encodes the data stored in its memory into a suitable format in advance of transmission. On the receiving end, it is verified whether the data packet has been compromised during transmission. Upon detection of an error, the transmitter sends back the faulty packet. Upon verification of the data packet's integrity, it is retained in the receiver's memory. Test configurations were created for various communication circumstances, and the suggested system was evaluated compared the traditional direct transmission method. The data were thoroughly evaluated for transmission speed and bit error rate.
