SUMMARY

MQTT is a lightweight messaging protocol designed for resource-constrained IoT devices, using the publish/subscribe model to facilitate efficient, real-time communication.

This protocol decouples publishers and subscribers, ensuring scalability, flexibility, and low overhead, making it ideal for IoT applications in environments with limited resources.

MQTT’s broker-based paradigm reduces bandwidth usage and supports asynchronous communication, which is particularly beneficial for devices that are intermittently online.

By leveraging MQTT, IoT devices can exchange data in a reliable, scalable, and efficient manner while minimizing power consumption and latency.

Learning outcomes

By the end of this module, learners will be able to clearly describe the MQTT publish/subscribe communication model, including the role of brokers and how this model supports efficient and decoupled messaging in IoT systems.
Within this course, learners will analyze and contrast MQTT with client-server communication models, identifying at least three specific advantages of MQTT in terms of bandwidth efficiency, scalability, and asynchronous messaging.
By completing the hands-on activity, learners will successfully configure an MQTT broker and set up at least one publisher and one subscriber to enable real-time data transfer for a basic IoT use case, such as temperature sensor monitoring.
