Internet of Things Architecture: Protocols, Security, and Data Flow
Internet of Things Architecture: Protocols, Security, and Data Flow IoT architectures connect sensors, devices, gateways, and cloud services. They need simple, reliable protocols, strong security, and clear data paths. This article explains core protocols, security basics, and how data moves from device to decision. Protocols that power IoT IoT devices vary in power and bandwidth. Choosing the right protocol helps keep devices responsive and affordable. MQTT: lightweight publish/subscribe, ideal for sensors sending small messages. CoAP: designed for constrained devices over UDP, with a simple request/response pattern. HTTP/HTTPS: widely supported, easy to integrate, but heavier for tiny devices. AMQP: robust enterprise messaging for complex flows and guaranteed delivery. Security in IoT Security must be built in from the start. Basic steps help prevent outages and data leaks. ...
