Open IOT Challenge: start-up
I participate in the Open IOT Challenge http://iot.eclipse.org/open-iot-challenge/ (of the Eclipse Foundation). For some time, I wondered: “How can I test my backends infrastructure with thousands of connected objects (or more) without these objects?”. My idea is to develop a simulator of things. So, my project is a software simulator of connected devices and gateways. It will be a DSL with Groovy http://www.groovy-lang.org/ and Golo http://golo-lang.org/ like this:
def coapGateway001 = new CoapGateway(id:"coapgw001", coapPort: 5683, execEnv: env, locationName: "Home")
def coapGateway002 = new CoapGateway(id:"coapgw002", coapPort: 5686, execEnv: env, locationName: "Work")
coapGateway001.sensors([
new DHTSensor(id:"dhtRoom1", locationName: "ROOM1"),
new DHTSensor(id:"dhtRoom2", locationName: "ROOM2"),
new LightSensor(id:"lightRoom9A", locationName: "ROOM9"),
new LightSensor(id:"lightRoom9B", locationName: "ROOM9")
]).start {
while (true) {
Thread.sleep(5000)
coapGateway001.notifyAllSensors()
}
}
coapGateway002.sensors([
new DHTSensor(id:"dhtRoom3",locationName: "OFFICE01"),
new DHTSensor(id:"dhtRoom4",locationName: "OFFICE02"),
new DHTSensor(id:"dhtRoom5",locationName: "OFFICE03"),
new SoundSensor(id:"soundRoom6",locationName: "OFFICE02"),
new DHTSensor(id:"dhtRoom7",locationName: "OFFICE04"),
new DHTSensor(id:"dhtRoom8",locationName: "OFFICE05"),
new SoundSensor(id:"soundRoom9",locationName: "OFFICE03"),
new DHTSensor(id:"dhtRoom10",locationName: "OFFICE06"),
])
.start {
while (true) {
Thread.sleep(5000)
coapGateway002.notifyAllSensors() // I want all data of my sensors each 5s
}
}Firstly, it will come with three kinds of Gateway simulators (software):
- CoAP,
- MQTT
- and “Virtual” (for tests)
and with some Sensors simulators (software) with random data (ie: DHT sensors, light, and even a herd of animals)
but the DSL will be extandable. This DSL will allow to test/stress existing IOT backend platforms too. For certain scenario, it will be scalable and with high availability (eg: create a virtual platform to query thousand of CoaP resources).
The implemented technologies will include:
- CoAP (Californium)
- MQTT (Paho)
- Groovy for the core DSL
- Golo to create specific DSL from the core DSL
- Vert-X and Hazelcast (high availability)
- Nodejs (and some frameworks)
- …
The project name is Atta, and you will be able (soon) to follow its progress on https://github.com/ant-colony/atta.
Stay tuned :)
