2. MQTT - Message Queuing Telemetry Transport A best protocol that suits for low power IoT Devices Features of MQTT includes  Light weight and bandwidth efficient and suitable for low power devices  Simple  QoS Data Delivery (At most once, At least once and Exactly once Qos Data Delivery)  Continuous Session Awareness
3. MQTT Broker MQTT Broker supports  Interoperability  Security (Authentication & Authorization, Payload encryption and signing, topic permissions)  Scaling  Bridging (Parallel Processing)  Clustering (High Availability)  Publish-Subscribe Design Pattern (Topic based flexible routing)  Subject based filtering
4. Publish a message  MQTT connector requires a client id to identify its client. Broker Server Uri is mentioned as "tcp://localhost:1883". Before deploying the application, start the Mosquitto server that resides in a machine.(MQTT broker).  To start a MQTT broker,  Open Services in Windows (In Start screen, search for "Services")  Locate the installed server "Mosquitto Broker" and change the status to "Running"
5. Subscribe a message  If a message is subscribed for a topic, then whenever a message is posted for a topic, broker sends the message to the other interested clients that subscribed.
