Internet of Things Data as a Service Module Broker (IoTDSM-B)

TL;DR

The Internet of Things Data as a Service Module Broker (IoTDSM-B) is a project developed in the Laboratory of Distributed Systems and Concurrent Programming (LaSDPC) of the University of São Paulo (USP). This tool aims to simplify the acquisition and communication of sensor data in the Internet of Things (IoT). For this, this tool supports different communication strategies, such as HTTP, MQTT and CoAP.

Installing

To install IoTDSM-B, compile the project with the command:

#Compile the project with all dependencies disregarding the execution of tests
~$ gradle build shadowJar

This command will generate a jar file with all dependencies required to execute the project. The generated jar is located in the directory path:

#File: iotdsm-broker-all-1.0.0.jar and iotdsm-broker-1.0.0.jar
~$ build/libs

If you only need to download the dependencies, execute the command:

~$ gradle build --refresh-dependencies

To execute the IoTDSM-B, just run the command:

#Executes IoTDSM-B
~$ java -jar iotdsm-broker-all-1.0.0.jar <args>

Running Tests

To run the unit tests just run the command:

#Perform Unit Tests
~$ gradle test

Running and Deployment

The IoTDSM-B provides an input interface for different configuration parameters. These parameters are passed through system-defined flags. To view the available parameters, execute the command:

#Shows the options parameters available
~$ java -jar iotdsm-broker-all-1.0.0.jar -help

The available parameters are as follows:

 -c,--configuration <arg>   Path to configuration file [config.properties].
 -h,--help                  Show help [true, false].
 -l,--log <arg>             Enable or disable log [true, false].
 -lf,--logfile <arg>        Log4J Configuration File [log4j.properties].
 -v,--log-level <arg>       Changes the log level [OFF, TRACE, DEBUG, WARN, ERROR, FATAL, ALL].

In addition, other settings can be defined by means of a configuration file. This file specifies the IoTDSM-B configuration enviroment. The Table 1, show the available arguments in the configuration file (config.properties).

Table 1: Web Server input variables.

Variable	Description
BROKER_PROTOCOL	Protocol Type (HTTP, MQTT or COAP)
BROKER_HOST	Broker Host Address
BROKER_PORT	Broker Port Address

These variables are passed through a configuration file (config.properties) through the command -c= ${config_file}.

~$ java -jar iotdsm-broker-all-1.0.0.jar -c=${config_file}

Docker Images

This project provides docker images for use in production. The following is the official docker file available. To compile the images in Docker from IoTDSM just run the command:

#To Compile Image (IoTDSM-B)
~$ docker build -f iotdsm-b.dockerfile -t iotdsm-b .
