What is the Internet Of Things?
●   The number of devices connected to the
    internet continues to grow every day
●   Creating data that may never be seen by a
    human
●   Rather than creating custom networks to send
    data, making use of ubiquitous IP networks
●   Smarter Planet/Smarter Cities/Smarter Cars
●   The number of
    devices connected to
    the internet
    continues to grow
    every day
HTTP | MQTT
MQTT features
●   Publish/Subscribe
●   1-to-many messaging
●   Hierarchical topic structures & wildcard
    subscriptions
●   3 QOS levels
    –   0 at most once
    –   1 at least once
    –   2 only once
●   Persistent messages
History
●
    Invented by Andy Stanford-
    Clark (IBM) and Arlen Nipper
    (Eurotech) in 1999
●
    Originally envisioned for use
    over satellite links from an oil
    pipe line
●   Home automation (Mouse trap
    messages)
●
    Twittering Ferries
Community
●   Protocol spec published
    royalty free in August 2010
    and started the journey to
    becoming a international
    standard
●   November 2011 IBM and
    Eurotech join the Eclipse M2M
    working group
●   mqtt.org
●   COSM

Demo
Mobile Use
  ●   Facebook Messenger
  ●   Push messaging
      –   No need for a 3rd party to handle data
  ●   Lower Power usage than HTTP Polling*
