COMPUTER-IMPLEMENTED METHOD FOR TRANSMITTING DATA IN LPWAN NETWORK BETWEEN A SUBSCRIBER STATION AND A BASE STATION

摘要

FIELD: information technology.;SUBSTANCE: invention relates to data transmission in LPWAN networks. Computer-implemented method for data transmission in LPWAN network between subscriber station (SS) and base station (BS), comprises steps of transmitting information from a base station, represented in form of a data packet from an application layer to a network to a physical layer, processing the transmitted information by splitting the transmitted data into separate blocks and adding each FragNum and LF fields, where the FragNum field value tracks the block number to obtain a packet consisting of blocks arranged in the correct order, and the value of the LF field indicates whether this unit is the last of all blocks forming the packet, further, in one of the units, adding the cryptographic signature of the Auth packet used for authenticating the subscriber station, converting the presentation or coding format of data in the block and adding to each block the corresponding level headers, encapsulating in each information unit transmitted through the physical layer information characterizing the selection of a protocol sequence for performing inverse transformations on the information receiving user station, subscriber station is authenticated, and the transmitted information is received by the authenticated subscriber station.;EFFECT: providing information transfer without packet loss by an authenticated subscriber station.;3 cl, 4 dwg
