OpenIoE

Open-source middleware platform for building, managing, and integrating connected products with the Internet of Everything.

Main features

• A high-perfomance Java server side with Spring Boot
• Message broker support with ActiveMQ Artemis
• Multi Protocol support (MQTT, AMQP)
• NoSQL data storage for sensor data (Cassandra)
• Support for timeline series modelling

Docker

• All the services required to run the platform can be easily started via bundled docker-compose.yml located in rest_api/src/main/docker
• Browse to rest_api/src/main/docker and run docker-compose up -d
• Open 127.0.0.1 in the web browser where you can configure a user account and create devices and sensors
• To stop the platform, run docker-compose stop in the same folder as above
• Logs can be observed via docker-compose logs [CONTAINER] (ex: ioe-app)

Installation

• Clone the Github repository
• Install and configure Cassandra (http://cassandra.apache.org/doc/latest/getting_started/installing.html)
• Configure 'ioe' section in application.yml that can be found in rest_api/src/main/resources/config

Usage

• Make sure Cassandra server is up
• Run Artemis message broker in a terminal using executable in /message_broker/bin
• Run Spring Boot backend by 'gradlew' executable in /rest_api
• Open 127.0.0.1 in the web browser where you can configure a user account and create devices and sensors

Storing data

Data can be stored via the REST endpoint and the message broker. Both methods accept the payload as JSON. An example is {"sensorId":1,"data":"24","description":"test","timestamp":"2016-07-30T21:29:34+02:00"}

Retreiving data

Using the REST end point data can be retreived. http://127.0.0.1:8080/api/sensors/1/data where 1 is the sensor id http://127.0.0.1:8080/api/sensors/1/data?dates=2016-07-30,2016-07-2 where multiple dates can be specified

• The request should pass the Authentication token

Future work

• Docker container for easier dev and prod deployments (ongoing)
• Authentication and access control for device and sensor end points
• Detailed documentation
