Smartwatch

The project aims to simulate a smartwatch in the role of publisher within the pub-sub paradigm using MQTT. The simple GUI allows to trigger all the functions of the core SmartWatch class, like connecting, measuring and publishing data. Fundamental is the presence and the coordination with an MQTT subscriber in order to make the application run properly.

General Information

• The maven project contains all the software needed to simulate the scenario. But during the presentation, I and my team's mate Christopher Zanoli are going to use his project as MQTT subscriber.
• The project intends to provide a standard approach on how to synchronize the message flow between publisher and subscriber as well as showing how to use the MQTT's Paho framework in a simple way.
• The purpose of the project is to prototype a medical environment where a smartwatch is responsible for measuring the data from the patient.

Technologies Used

• Java - version 1.8
• Paho - version 1.2.1
• Gson - version 2.8.6
• Logback - version 1.0.13

Setup

Clone the repo from my GitHub https://github.com/jackma-00/IoTSmartWatchProject.git and open it as a IntelliJ project.

Note you need valid and effective credentials in order to use the cloud broker. Here in the repo's code credentials are ineffective for privacy reasons.

Usage

Simplest way

First run SmartWatchProcess (on the process package) and then MqttHandlerProcess (on the serverside package).

Fully potential

Run SmartWatchProcessGUI (on the process package), simultaneously run the subscriber process on Chris's machine. Then keep caution about the following coordination step:

1. Press the button 'on'.
2. Press the button 'start'.
3. Make a post request on Chris's server.
4. Press the button 'send' to measure and send the results to Chris.
5. At this point you can either start a new cycle of measurements going back to the point 2. or press the button 'off' to disconnect the client and turn off the device.

Project Status

Project is complete for the exam's presentation.

Room for Improvement

Room for improvement:

• Improve the GUI
• Improve the process of synchronization between publisher and subscriber
• support a local broker installed within the LAN
