  • 16. Technology
  • 17. The Connectivity Challenge The challenges of industrial control systems (supervisory control and data acquisition, or SCADA) well-suited to a messaging solution  Loose coupling, multi-protocol, separation of concerns... Connectivity to remote field systems could be costly Networks could be unreliable (satellite, GPRS, mesh, proprietary protocols) Conditions could be constrained (environment, hardware, power) Thousands of sensors or devices may be involved in monitoring a system
  • 18. Connectivity for M2M with MQTT ■ MQ Telemetry Transport (MQTT) is designed with the following primary intentions: – Publish/subscribe messaging paradigm as required by the majority of SCADA and sensor applications. – Minimise the on-the-wire footprint. – Expect and cater for frequent network disruption, cope with slow and poor quality networks: built for low bandwidth, high latency, unreliable, high cost networks – Expect that client applications may have very limited processing resources available. – Provide traditional messaging qualities of service where the environment allows – Publish the protocol for ease of adoption by device vendors and third-party client software.
  • 19. Show us some code!public void sendAMessage() throws MqttException { MqttProperties mqttProps = new MqttProperties(); Create a connection using the mqttProps.setCleanStart( true ); connection factory, this time for a MqttClient client = MqttClientFactory.INSTANCE. clean starting client createMqttClient("testClient", “tcp://localhost:1883”, mqttProps); client.registerCallback(this); Register the class as a listener and client.connect(); connect to the broker client.publish(“abc/123”, new MqttPayload((“Hello World!”).getBytes(),0), (byte) 2, false); Publish a message to the client.disconnect(); given topic and disconnect}public void publishArrived(String topicName, MqttPayload payload, byte qos, boolean retained, On receipt of a publication, simply print int msgId) { out a message on the console to say we System.out.println(“Got it!”); received it}
  • 20. Surely HTTP is everywhere? Why use MQTT?
  • 21. Data-centricityMQTT is agnostic of data content and transferssimple byte arrays, making drip-feeds of updatinginformation trivial.HTTP is (basically) document-centric.
  • 22. SimplicityMQTT has few methods (publish/subscribe/unsubscribe) and is quick to learn.HTTP can be complex (although it is often well-understood) - there are a multitude of return codesand methods. REST is a great principle but not always the best forsimple data applications (POST/PUT/GET/DELETE?er what?)
  • 23. Light on the networkThe smallest possible packet size for an MQTTmessage is 2 bytes. The protocol was optimised from the start forunreliable, low-bandwidth, expensive, high-latencynetworks.HTTP is relatively verbose - lots of "chatter" in aPOST
  • 24. Easy distribution of dataMQTT distributes 1-to-none, 1-to-1 or 1-to-n via thepublish/subscribe mechanism→ very efficientHTTP is point-to-point (can be mediated/clusteredbut no distribution mechanism). To distribute tomultiple receivers a large number of POSTs may berequired.
  • 25. Lightweight Stack (CPU/Mem)MQTT has been trivially implemented on tiny tolarger platforms in very small libraries[IBM ref implementation = ~80Kb for full broker]HTTP (often with associated XML or JSON librariesfor SOAP and REST etc) can be relatively large ontop of OS network librariesPlus... even if the client is small, consider whether itis really necessary to run an HTTP server on everydevice
  • 26. Variable Quality-of-ServiceMQTT supports fire-and-forget or fire-and-confirm(aka QoS 0/1/2)HTTP has no retry / confirmation / attempt at once-only delivery. It is basically brittle, i.e. retry needs tobe written in at the application level. Applicationsmust also handle timeouts.
  • 27. Simple, small and portable- so home hackers like using it!
  • 28. Examples
  • 29. Smarter Healthcare Medical organization created a remote pace-maker monitoring solution to provide better patient care  Physicians needed better monitoring of cardiac patients  Improve efficiency of checkups  Meet healthcare data capture standards Enables higher level of patient care and peace of mind Improves administrative efficiency and maintenance Helps conform to standards and ease integration of data
  • 30. Smarter Energy Utility company developing an Intelligent Utility Network offering for optimizing load on electricity grids  Needs robust middleware technology to connect to remote smart meters  Needs to be able to rapidly scale solution nationally Able to offer daily energy savings of 15-20% Enables utilities to reduce peaks and avoid punitive charges Helps save electricity through better peak load management
