Simulator of WTF (Wearable Ticket for Festivals)

This repository contains the code to simulate the runtime behavior and performances of an embedded system. In our case the embedded system is a bracelet, which is worn by festival guests and allows them to find their friends by means of a P2P network of bracelets. More on this in the paper

This project was carried out as final project for the DTU course, Fundamentals of Modern Embedded Systems 02223

Introduction

The simulator is split into

• Backend (Simulator)
• Frontend (Web UI)

Backend/Simulator

Make sure maven is installed on the host

Open the terminal in the root folder and run the following command

mvn package

Usage

The simulator can simulate two communication algorithms:

• Broadcast (video)
• Search Request (video)

More on this in the paper.

In order to run the change the mode it is necessary to change runSR boolean value in Simulator class:

@PostConstruct
public void start() {
	new Thread(() -> {
		try {
			Thread.sleep(5000);
			boolean runSR = true;
            ...

The configurations for the events and properties of the system and bracelet are defined in resources:

• event.txt (what happens in the system)
• params.txt (the characteristics of the bracelet in Braodcase)
• SRparams.txt (the characteristics of the bracelet in Search Request)

Running the simulator

java -jar ./backend/target/*.jar

The HTTP interface

The Simulator will expose internal information and statistics through a REST API. The default port is 8080.

Frontend (Web UI)

It is developed in Javascript, using the library P5. It is enough to open this file in the browser, once the simulator is running. The UI and the simulator talk using REST APIs. The default port both use is 8080. Change it in both if necessary.
