Ovaj rad opisuje implementaciju jednostavne arhitekture sustava Interneta stvari. Najprije se opisuju komponente arhitekture. Komponente arhitekture su korisnička aplikacija, servisu u oblaku, pristupnik i naprave. Zatim se opisuje aplikacijski protokol koji naprave u sustavu koriste. Nakon toga opisuje se implementacija i komunikacija komponenti sustava.This thesis describes the implementation of a simple Internet of Things architecture. At the beginning, components of the architecture are described. Components of the system are user application, cloud service, gateway and devices. Following that, the communication protocol used by smart devices in the system is explained. In the end, implementation and communication of system components i...
