The Internet of Things
Hype or revolution?

Internet of Things?
+

Top Trend in 2014
IEEE Computing: #1
Internet of Things
The IoT promises to be the most disruptive technological revolution since the
advent of the World Wide Web.
GARTNER: Top Ten
Gartner Says the Internet of Things Installed Base Will Grow to 26 Billion
Units By 2020
Projections indicate that up to 100 billion uniquely identifiable objects will be
connected to the Internet by 2020, with enormous technical, socioeconomic,
political, and even spiritual consequences.
Top Tech Trends

Multiple Definitions
Cisco “Internet of Everything”
…the latest wave of the Internet -- connecting physical objects…to provide
better safety, comfort, and efficiency
IBM “Internet of Things”
…a completely new world-wide web, one comprised of the messages that
digitally empowered devices would send to one another. It is the same Internet,
but not the same Web.
GE “Industrial Internet”
…convergence of machine and intelligent data…to create brilliant machines
RTI “Your Systems. Working as One.”
…an entirely new utility. As profound as the cell network, GPS, or the Internet
itself. The Internet of Things and the Intelligent Systems it enables will
fundamentally change our world.

DATA DISTRIBUTION

Data Distribution Service
a real time communication technology
standard for the Internet of Things

Publish/Subscribe
● Paradigm shift:
○ From “give me your information” to “send me your data have when
you have more”
● Applications specify what can provide and what are they interested in
○ Middleware handles sending, reception and conversion
○ e.g. “I offer temperature data”, “I’m interested in pressure data”
● Applications are matched by interests:
Temp
Publisher
Temp
Subscriber
Temp
Subscriber
Pressure
Subscriber

Data Centric Model
● Data drive the communication
○ Data type and content define the interactions
○ e.g. Temperature data
● Topic is the exchange unit
○ Name + Type
○ Samples are univocally identified by keys (like in DB)
○ QoS per publication: matched vs. offered
● Global Data Space
○ Applications publish topics to a global data space
○ Global shared cache

Data Centric Model
● Decentralized
● Acts as a distributed database/cache
● No servers involved
