3. What’s in a Name? Pervasive Computing by any other name?
Why “Internet”?
Some other kind of network, previously or potentially?
An internet or the Internet?
No network?
Why “Things”?
Were things excluded before ?! (switches, routers, …)
Anything? Everything?
Any specific type of things?
Pervasive Computing by any other name?
CPS, Ubiquitous Computing, physical computing, SmartX

4. Usecases What is a good/canonical IoT usecase?
Mercury-filament thermostat?
Digital thermostat?
Remotely accessible from Internet?
Integrating usage data from other households?
Mashed with a lookup of upcoming weather?
What if all of the above but with:
A thermometer? A raingauge?
A traffic measurement PC application?
What about an Internet doorbell?

5. Usecases Consider the following usecase
Bicyclists and pedestrians with GPS, connected heart-rate/bp/blood-oxy meters, augmented reality glasses; stationary and mobile connected air quality monitors
When they turn to look in some direction, AR display provides detailed/digested information about personalized risk by smart integration of data from sensors, historical data of health incidents of users correlated with historical sensor data
What does it take to get this done?

9. Summary
We will try to identify “IoT” concepts worth studying (with higher generality, more explanatory power)
We will study underlying concepts required to make the system components fit together
We will enumerate some and experiment with a few exemplars from each component category
