  27. MQTT Message Queue Telemetry Transport

  28. What is MQTT ? MQTT stands for MQ Telemetry Transport. • It is a publish/subscribe, • extremely simple and • lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. It is used on top of TCP Protocol

  29. Why MQTT Created ? MQTT was created with the goal of collecting data from many devices and then transporting that data to the IT infrastructure. It is lightweight, and therefore ideal for remote monitoring, especially in M2M connections that require a small code footprint or where network bandwidth is limited.

  30. Who uses MQTT ? • MQTT was originally developed for the low-bandwidth, high-latency data links used in the oil and gas industry. • Controlling smart lighting systems • Facebook Messenger application. • Amazon Web Services recently announced that Amazon Internet of Things (IoT) is based on MQTT, as well. 

  31. How does MQTT works ? • MQTT is a publish/subscribe protocol that allows edge-of-network devices to publish to a broker. • Clients connect to this broker, which then mediates communication between the two devices. • Each device can subscribe, or register, to particular topics. • When another client publishes a message on a subscribed topic, the broker forwards the message to any client that has subscribed.

  32. MQTT Brokers and Clients • Mosquitto • Mosquitto is an Open Source MQTT server with C and C++ client libraries. • Eclipse Paho • The Eclipse Paho project provides open-source client implementations of MQTT and MQTT-SN messaging protocols aimed at new, existing, and emerging applications for the Internet of Things (IoT).

  38. If This Then That, also known as IFTTT, is a free web-based service to create chains of simple conditional statements, called applets. An applet is triggered by changes that occur within other web services such as Gmail, Facebook, Telegram, Instagram, or Pinterest.
