IoTcontrollers
IoT controllers are central components in Internet of Things systems that manage and coordinate devices, sensors, and actuators. They may be deployed as dedicated hardware gateways, embedded software on edge devices, or cloud-based services. Their primary role is to enable device provisioning, data collection, process automation, and secure communication across an IoT network.
Key functions include device registry and provisioning, rule and workflow management, data routing and filtering, edge
Architectures vary: edge controllers run close to devices and handle local decision making with low latency;
Protocols and standards: commonly used protocols are MQTT, CoAP, HTTP, and AMQP. Security features include mutual
Deployment and applications: used in homes for automation, in industrial settings for asset monitoring and process
Challenges and considerations: ensuring interoperability across devices, scaling to large fleets, securing devices and data, and
