Internet of Things

is here!


EveryTHING is connected

My tells my that the is over

My tells my to open the garage and start my

My tells my that an intruder is entred

A tells my to tell my that a arrived


Internet of Things: Many different technologies


MQTT, a messaging protocol for IoT

Open (standard, 40+ client implementations)

Lightweight (minimal overhead, efficient format, tiny clients)

Reliable (QoS for reliability in unrealiable neworks)

Simple (43-pages specification, connect/publish/subscribe)

Late 90s Aug 2010 Nov 2011 Sep 2014

Invented by and Published by Eclipse M2m Standard

(v. 3.1.1)


MQTT v.s. HTTP


MQTT: publis/subscribe

Thanks to Bryan Boyd (http://www.slideshare.net/BryanBoyd/mqtt-austin-api)


MQTT: payload agnostic



MQTT: wildcard subscriptions



MQTT: quality of service



MQTT: retained message for last value caching



MQTT: cleanSession for session state



MQTT: last will and testament
