Varhola, Oliver ; Zeman, Václav (oponent) ; Škorpil, Vladislav (vedoucí práce)
This master thesis contains a proposal of the solution for economical and energy saving security device with its communications part in a LoRaWAN network. Theoretical part of the thesis describes the most widespread LPWAN networks, i.e. the networks for low-power devices, such as NB-IOT based on LTE technology, Sigfox and LoRaWAN. Also briefly analyses security threats in case of the interference exploitation of the communication channel and describes LoRaWan security in detail. In the practical part there is hardware, power, mechanical solution implemented including the cover of the device. Realization of the software part covers, which types of events should be operated, power saving methods and mesage sending inverval are described. All requirements were implemented at application layer utilizing - LoRaWAN network server and virtual machine applications: MQTT broker, NoreRED, OpenHAB and cloud database InfluxDB with visualisation of the data in Grafana application.
