4. History with IoT related Technologies
(Processors, communication, Sensors))
• 1978-85: SSMA and frequency hopping secure communication
systems
• 1985/86: Intel 8086 based real-time processor for drones
• 1986- 1991: M6800x and Intel x86 based processor and I/O
controllers development at HCL Development lab
• 1987: Developed and published a practical manual of designing
processor devices, interfacing with sensor, into products. Hardly
any books by Indian writers were available back then
• 1992- 2008: Software projects execution for International clientele .
Worked with the client-server, web based technologies, digital
media technologies for digital video broadcasts and IPTV
applications
• 209 to now: Consultancy, strategy, technology mentoring in areas
including embedded technology

5. Internet of Things
• This is an evolving technology, also known as Internet
of Everything.
• Evolved from what used to be known as Ubiquitous
computing, M2M
• The industrial section of the applications are being
hailed as the 4th industrial revolution
• Basic premise is that intelligent/smart objects will be
delivering data to the Internet repositories and be
controlled through it
• Because of the Internet, this control will be possible
from anywhere
• That opens up a whole lot of possibilities

10. Classes of Constrained Devices
Class RAM Flash Comments
Class 0 < 1 KB < 100 KB Devices use gateways to communicate, have
rudimentary communication capabilities only
Class 1 ~10 KB ~100 KB Devices use protocols designed for IoT, using
Constrained Application Protocols (CoAP). Can
interact with other devices without going through
a gateway.
Class 2 ~50 KB ~250 KB Devices use regular IP (IPv6) protocols and can
behave as regular network devices
11/20/2015 Debasis Das ECD Zone 10

11. What is CoAP
• CoAP is
– A RESTful protocol , for constrained devices and
networks, It is specialized for M2M applications
– Easy to proxy to/from HTTP
• CoAP is not
• A replacement for HTTP but a general HTTP
compression
• Works within the current web environment
facilitating communication of constrained devices

14. OS with Raspberry Pi
• Raspabian
• Arch Linux ARM
• OpenELEC
• Pidora
• Raspbmc
• Minepeon
• Kali Linux
• OpenWrt for
Raspberry Pi
• Raspberry Digital

15. OS with Arduino
• DuinOS
• Pyxis OS
• ArduinoMacOS
• TaOS
• FreeRTOS
• ROS
11/20/2015 Debasis Das ECD Zone 15

16. Contiki
• Open source OS that includes support for the
communication protocols
• Supports Internet standards
– 6LowPAN, RPL, COAP
• Supports standard C and COOJA simulator
• Runs on a range of low power wireless devices
• Commercial support available in addition to community
support
11/20/2015 Debasis Das ECD Zone 16

17. COOJA
• Cooja is a Contiki network emulator
– An extensible Java-based simulator capable of emulating Tmote Sky (and
other) nodes
– The code to be executed by the node is the exact same firmware you may
upload to physical nodes, allows large and small networks of motes to be
simulated
– Motes can be emulated at the hardware level
• Slower but allows for precise inspection of system behavior
– Motes can also be emulated at a less detailed level
• Faster and allows simulation of larger networks
• Cooja is a highly useful tool for Contiki development
– It allows developers to test their code and systems long before running it on
the target hardware
– Developers regularly set up new simulations to
• debug their software
• to verify the behavior of their systems

18. KAA
11/20/2015 Debasis Das ECD Zone 18

19. KAA Features
• Kaa is a middleware platform for creation of IoT
solutions, customizable, transport-agnostic link
between the hardware and applications
• It can build active device inventory, capture physical
and logical specs for each device, collect and analyze
real-time telemetry data, perform device management,
provisioning, and configuration, distribute firmware
updates, Enable near real-time communication across
devices
• Complex, time-consuming, and mundane tasks can be
left to Kaa
11/20/2015 Debasis Das ECD Zone 19

20. KAA Advantages
• Deployed easily deployed: on-premises, in cloud,
or mixed environments
• Supports wide range of hardware from low-
power MCUs to major OS supported systems
• Can use virtually any communication layer
• Promotes structured data that is easy to use and
handle
• The Kaa server can be scaled up to handle
millions of connected devices

21. In Conclusion
• Like most new technologies things are in a flux
• As with such evolving technologies, there are
several proprietary tools available to be
followed by open-source ones
• There are enough free source tools to get
started with development projects
