Lesson 1: IoT Architecture Layers & Protocol Selection (MQTT vs HTTP)

Summary & Core Concepts

Compare IoT communication protocols: discover why MQTT's compact binary headers and pub/sub model excel over heavy HTTP for low-power constrained sensors.

Key Takeaways

Four-layer IoT stack: Perception -> Network -> Middleware -> Application
MQTT broker publish/subscribe decoupled topology
Quality of Service levels: QoS 0 (At most once), QoS 1 (At least once), QoS 2 (Exactly once)
