ODL-DSBA Building IOT Applications

•How do IoT application protocols contribute to seamless communication between IoT devices in heterogeneous environments?

•Compare the architecture of HTTP, CoAP, MQTT, and AMQP in terms of their messaging paradigms and network models.

•Describe the differences between the publish/subscribe model used by MQTT and the request/response model used by HTTP.

•Discuss the role of security features in IoT application protocols and the potential risks of insecure protocols.

•Provide examples of IoT applications that benefit from the use of HTTP, CoAP, MQTT, or AMQP, and explain the rationale behind the selection.
