The Internet of Things

“The Internet of Things is Made of
Signals”

Actually…People PLUS
• Objects
• Services
• Sensors
• … Things
!
Basically: a lot more endpoints…

@andypiper @mqttorg#oscon #mqtt
Endpoints emit data (warning, can get messy)

@andypiper @mqttorg#oscon #mqtt
The Web is request/response Web Services ~ RPC
![Page 9: Internet ALL the Things - a walking tour of MQTT](https://reader034.vdocuments.site/reader034/viewer/2022051311/540d68b08d7f728d7e8b48fc/html5/thumbnails/9.jpg)
@andypiper @mqttorg#oscon #mqtt
HTTP is document-centric (is it as good for signals?)

@andypiper @mqttorg#oscon #mqtt
Signals are emit/respond (the IoT is NOT the web)

Protocol: MQTT
![Page 13: Internet ALL the Things - a walking tour of MQTT](https://reader034.vdocuments.site/reader034/viewer/2022051311/540d68b08d7f728d7e8b48fc/html5/thumbnails/13.jpg)
The “Industrial Internet”?
@andypiper @mqttorg#oscon #mqtt
Fifteen years ago…
• 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

@andypiper @mqttorg#oscon #mqtt
http://mosquitto.org !
C, small standalone binary, fast, standards-compliant/complete, MQTT only !
e.g. Ubuntu: sudo apt-get install mosquitto e.g. OS X: brew install mosquitto
http://rabbitmq.com !
Erlang, enterprise-quality, larger footprint, MQTT plugin to AMQP (++) broker, not 100% of spec (yet) !
e.g. Ubuntu: sudo apt-get install rabbitmq e.g. OS X: brew install rabbitmq

(some) more brokers!!
! Eclipse moquetteCode coming soon from existing project; aiming to be OSGi-compliant !
! ActiveMQ 5.9 http://activemq.apache.org/Includes MQTT support; broader set of protocols !
! HiveMQ http://hivemq.comStandalone Java MQTT broker; not open source, free for personal use !
! GnatMQ http://m2mqtt.wordpress.com/.NET broker
! … many more!

By August 2011 (third OggCamp): !
• Client APIs in ~12 languages, for Arduino, mBed etc.
• Specification published royalty-free in 2010
• IBM and Eurotech open call for Standardisation participation
• Adopted by Facebook Messenger…

@andypiper @mqttorg#oscon #mqtt
Today! !
• Too many clients to count • New commercial and OSS
brokers • MQTT 3.1.1 standard from OASIS • Core Eclipse IoT Projects (Paho,
Mosquitto, Moquette) • Paho graduated with Eclipse Luna
