7. Types of Communicaton

8. Protocols
• MQTT:
• XMPP:
• DDS:
• AMQP:

9. MQTT
Message Queue Telemetry Transport
● • MQTT: a protocol for collecting device data and
communicating it to servers (D2S)
● implements a hub-and-spoke system.
●

10. XMPP
Extensible Messaging and Presence Protocol
● a protocol best for connecting devices to people, a
special case of the D2S pattern, since people are
connected to the servers

11. DDS
Data Distribution Service
● a fast bus for integrating intelligent machines (D2D)
● DDS’s main purpose is to connect devices to other
devices.

12. AMQP
Advanced Message Queuing Protocol
a queuing system designed to connect servers to each
other (S2S)
It sends transactional messages between servers.

13. Types of Devices in IoT

14. Softwares in IoT
● Yokto Project
● RIOT OS
● Mbed project
● Tiny OS
● Lite OS
● Mantis
●

15. RIOT OS
● RIOT is an open-source operating system for the
Internet of Things
● License:LGPL
● Supports : C and C++
● RIOT runs on 16bit hardware (such as TI MSP430) and
32bit hardware (such as ARM Cortex)
● Needs 1.5 KB ram and 5kB ROM !

16. Yokto Project
It's not an embedded Linux distribution
– it creates a custom one for you
From tiny scale to a full feature scale

17. ARM Projects
(including mbed )

18. Concerns
1. Privacy Concerns:
2. Insufficient Authentication/Authorization
3. Transport Encryption
4. Web Interface
5. Insecure Software

19. Thank You !
