    Study Notes

    XMPP

    • XMPP stands for Extensible Messaging and Presence Protocol.
    • XMPP is an open standard protocol.

    AMQP

    • AMQP stands for Advanced Message Queuing Protocol.
    • The basic unit of data in the AMQP protocol is called a frame.
    • The exchange types in AMQP are Direct, Fan-out, Topic, and Header.

    MQTT

    • The full form of MQTT is Message Queue Telemetry Transport.
    • In MQTT, a message broker controls the publish-subscribe messaging pattern.
    • Publishers in MQTT are lightweight sensors.
    • The methods in MQTT include Connect, Disconnect, Subscribe, Unsubscribe, and Publish.

    CoAP

    • CoAP has been designed for Machine to Machine (M2M) applications such as smart energy and building automation.
    • Similar to HTTP, CoAP utilizes GET, PUT, PUSH, DELETE message requests to retrieve, create, update, and delete, respectively.

    IoT Networks

    • IoT networks can be classified into two types: Non-Beacon Enabled and Beacon Enabled.

    OSI Model

    • The OSI model has 7 layers.

    IPv4

    • The “Destination Address” in the IPv4 packet represents the address of the destination node in the network.
