Implementation of MQTT Native Application for Tizen-Based Smartwatches

Connected devices in IoT as well as the smartwatch market are getting more and more popular every year. The main mode of communication in IoT is an easy-to-use MQTT protocol suitable for devices with limited resources and battery power. Tizen is used for platforms such as mobile devices, smartwatches, TVs and even Linux kernel-based IoT devices. In this paper, we explain how MQTT protocol, Tizen operating systems and their architecture work, and suggest one possible implementation of a MQTT protocol for Smartwatches based on the Tizen operating system. We list the types of Tizen applications, develop a native application, and suggest possible future upgrades and appliances in IoT.
