IoT Protocols and Interoperability
IoT Protocols and Interoperability IoT projects grow quickly when devices from different vendors can talk to each other. Interoperability means systems, apps, and analytics can share data without custom adapters. The challenge is to balance device limits with reliable, secure communication across networks. A thoughtful protocol choice helps prevent silos and reduces integration costs. Common protocol families include MQTT for lightweight messaging, CoAP for constrained networks, and OPC UA for industrial data models. MQTT runs over TCP and supports quality-of-service levels. CoAP uses UDP and can cooperate with RESTful patterns. For factory floors, OPC UA provides semantic data models and robust security. In smart homes, a mix of MQTT and HTTP-based APIs often works well, while logistics use gateways to connect tracking sensors to enterprise systems. ...
