What is the pub-sub model in IoT?
The pub-sub model in IoT is a messaging pattern where devices (publishers) send messages to a topic, and other devices (subscribers) receive messages from that topic without direct communication.
How does it improve communication between devices?
It decouples the producers and consumers of data, allowing for more scalable and flexible communication. Devices can join or leave without affecting the overall system.
Can you give an example of its application?
Sure! A smart home system where sensors publish data about temperature or motion, and the central hub subscribes to these topics to automate actions like adjusting the thermostat.
What are the advantages of using pub-sub over traditional methods?
Advantages include scalability, reduced complexity, and improved fault tolerance, as devices don't need to know about each other directly.
