Abstract

Prijenos ažuriranja programske podrške u LPWAN mrežama je otvoreno pitanje za koje trenutno ne postoji opće prihvaćeni odgovor.
U ovom radu predlažu se dva algoritma za prijenos datoteke s mrežnog pristupnika na krajnje uređaje u mreži pri čemu se koristi tehnologija LoRa.
Jedan algoritam zahtijeva dvosmjernu komunikaciju između mrežnog pristupnika i krajnjih uređaja i ažuriranje prenosi koristeći silazni mrežni paket, a drugi algoritam emitira ažuriranje s mrežnog pristupnika na krajnje uređaje uz mogućnost kontaktiranja drugih krajnjih uređaja za dijelove koji nisu uspješno stigli s pristupnika.
Za osiguranje cjelovitosti poruke koristi se CRC algoritam.

Abstract (english)

Firmware upgrade transfer in LPWAN networks is an open question with no generally accepted answer as of now.
This thesis proposes two algorithms meant for transferring a file from gateway to end devices in a network using LoRa technology.
One algorithm requires a two-way communication between gateway and end devices and transfers the upgrade using a downlink packet, while other broadcasts the upgrade from gateway to end devices with a possibility of contacting other devices for parts which weren't transferred correctly from gateway.
Message integrity check is implemented using CRC algorithm.
