The present disclosure relates to a data reconstruction method for reconstructing data sent from at least one connected object to an addressee via a transmission architecture including at least one low-rate network. The method includes encoding the data as messages and dividing each of the messages into segments. Initial segmentation information for each segment is supplied during the dividing of each of the messages. The method further includes encapsulating each segment in a packet associated with a header and routing the packets via base stations in the at least one low-rate network. The method further includes reconstructing each of the messages from the packets received to generate reconstituted messages. The reconstructing is based on the initial segmentation information and is further based on subsequent sequencing validation of sequencing of the one or more intermediate segments. The method further includes transmitting each reconstituted message to the addressee.
