• This is a machine-to-machine communication protocol widely used in industrial
automation, developed by the OPC Foundation.
• This follows a client-server model
• Platform Independent!

12. Internet of Things – Sub topics for this course
www.tharinduweerasinghe.com
• MQTT
• A messaging protocol for the Internet of Things (IoT).
• It is designed as an extremely lightweight publish/subscribe messaging transport that
is ideal for connecting remote devices with a small code footprint and minimal
network bandwidth.
• MQTT today is used in a wide variety of industries, such as automotive,
manufacturing, telecommunications, oil and gas, etc.
Reference:
MQTT - The Standard for IoT Messaging

13. MQ – comes from the IBM
MQ (i.e. 'MQSeries’)
TT- Telemetry Transport

16. Block-Chain
www.tharinduweerasinghe.com
Concept in my own wording:
A very smart set of secured digital records or journal that contains some “DATA”,
their integrity(or validity) information!
The name Blockchain comes as each record (block) has set of data attached to it!
This mechanism is very handsome not only in Cryptocurrency but also in various
other industries!
