There are more than 450 IoT platforms today. These platforms create isolated silos with their own devices, and the devices can not exchange data between platforms. To solve this problem, CESAR is developing the KNoT meta-platform, which presents an architectural interoperability framework for IoT.

1. KNOT
A FRAMEWORK FOR IOT INTEROPERABILITY

3. Private innovation center
that creates products,
services and business
using information and
communication
technologies (ICT).

4. Identify, potentialize and
realize opportunities for
transformation of
organizations and
people's lives

5. WHY YOUR HOME DEVICES
ARE STILL NOT CONNECTED
TO THE INTERNET?

6. WHAT IS THE
INTERNET OF THINGS?

7. IOT IN A NUTSHELL

8. IOT IN A [COCO]NUTSHELL

9. IOT IN A [COCO]NUTSHELL
OU
IOT EM UMA “QUENGA” DE COCO

10. Embed connectivity,
sensors and actuators for
sharing data across mutiple
devices to add more
value.

12. IOT EM UMA “QUENGA” DE CÔCO
WHY YOUR HOME DEVICES ARE STILL NOT CONNECTED TO THE INTERNET?
conectividade para as coisas Every "thing" has its specific
connectivity needs:
▸ communication range
▸ baud rate
▸ power consumption
▸ cost

13. IOT EM UMA “QUENGA” DE CÔCO
WHY YOUR HOME DEVICES ARE STILL NOT CONNECTED TO THE INTERNET?
conectividade para as coisas…and this leads to many protocols
and protocol stacks
▸ physical layer
▸ data link and network layer
▸ transport layer

14. IOT EM UMA “QUENGA” DE CÔCO
THERE IS NO STANDARD YET
conectividade para as coisas
“It is very difficult to have a unique
standard for IoT as we have for the WWW,
with HTML and browsers. The THINGS in IoT
are so different and the applications as
diverse that many standards and protocols
will coexist.”

15. IOT EM UMA “QUENGA" DE CÔCO
IT GENERATES A PROBLEM
Complexity

18. HOW TO MITIGATE THIS COMPLEXITY?
Software platforms
Cloud services to exchange data
across devices

19. HOW TO MITIGATE THIS COMPLEXITY?
Hardware platforms
Wireless microcontrollers
+ sensors to develop your
application

INTEROPERABILITY

21. Applications have its
own protocols…
…and they didn't talk to
each other.

22. What are we doing?

24. We are not creating one
more IoT platform!

25. meta plataform for IoT
bridging the gap between existing platforms
made on top of them

26. IoT platforms
software
hardware

27. IoT platforms

28. IoT platforms

29. IoT platforms
software

30. open source, hardware
and software.

31. multi protocol
for the physical (multi radios), data link, network and
transport layers
To address all communication needs.

32. end to end
from the device to the app, crossing radios, gateways
and cloud services.

33. data sharing by space and time
“to share the data only on monday, from 2pm to 3pm.”

34. semantic data model
applications will know the data type of each other.

35. distributed cloud
a distributed system can handle billions of devices.

36. low cost
the maximum cost of cheapest device will be $5.

37. easy to use
the developer only needs to implement 3 functions to
have a device connected to the internet.

38. architecture 1.0

39. Hardware - Maker Board

40. Hardware - Dev Board

41. Hardware - KNoT Mesh

42. Why are we doing it?

43. Construction of applied knowledge
The group's researches turns into
experiments in observatories,
enabling CESAR to apply the
knowledge acquired in IoT
projects.

44. Integrate many platforms into a unique one
It allows interoperability across platforms and across data
from many devices.

45. More agility in developing IoT projects
A KNoT Lamp can be simple like this:
1. Get a KNoT device core schematic and customize it
by adding a lamp actuator.
2. Write 3 functions on KNoT μOS that define your
lamp behavior.
3. Write a mobile app using KNoT lib to interact with
the lamp.
