The Internet of ThingsHype or revolution?


Internet of Things?

Top Trend in 2014

IEEE Computing: #1 Internet of ThingsThe 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 2020Projections 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 efficiencyIBM “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 machinesRTI “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 Servicea 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

TempSubscriber

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

Temp Writer

Topic: Temp

Data Centric Model

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