IoT Protocols - INI

IoT protocols are communication conventions for enabling data exchange between devices in Internet of Things environments. Centered around lightweight messaging protocols such as MQTT, CoAP, and AMQP, various protocols exist to meet different use cases and requirements, including XMPP, DDS, HTTP, and LwM2M. These protocols are designed to accommodate the characteristics of IoT devices, including bandwidth constraints, power consumption, latency, and reliability. They are widely utilized across diverse fields such as smart homes, industrial automation, smart cities, and healthcare.
