2020s will be the age of
intelligent connected systems
“They are characterized by things connected through ubiquitous
networks to our systems, and providing not only services but
intelligent assistance, that is, some algorithmic manipulation of
big data to foresee and manage future needs.” [Woods16]

In architectural terms
Billions of communicating hw/sw components,
interacting alltogether (but following different
standards) to reach a goal

CAPS for decision making
- Which solution is more e.g.
energy efficient?
- Which architecture
decisions may limit the
amount of data created,
transferred, and analyzed?
- Which communication
topology to use?

To conclude
Engineering the IoT is still very challenging
Engineering the IoT is very important
Come with us to engineer the next IoT
