Describe the various IoT communication models with examples.
Answer
IoT uses various models like Request-Response and Publish-Subscribe to exchange data.
IoT communication models define how data is exchanged between entities. 1. Request-Response: A client sends a request to a server, and the server processes it and sends back a response. It is stateless. 2. Publish-Subscribe: Clients (publishers) send messages to a central broker (like MQTT), which distributes them to clients (subscribers) interested in that topic. 3. Push-Pull: Data producers push data to a queue, and consumers pull data from it, decoupling the generation and consumption rates.
