Abstract
Some protocols for the transmission of data on a communication network, such as the LoRaWAN protocol, use frames comprising payloads intended to transport useful data, the size of which may vary from one frame to another. A communication method is proposed in order to transmit data on this type of network. This method is based on a division of a payload packet into a set of blocks and then an insertion of the blocks thus formed into at least one segment. Each segment comprises a number of blocks suited to a payload size at the time of creation of the segment. The segments are next supplemented with verification information enabling an addressee of the data packet to determine whether it has received all the blocks. In the event of non-reception of all the blocks, the sender of the blocks retransmits at least the blocks not received.
