What we have learnt
- IoT architecture consists of multiple layers that separate responsibilities for better management.
- Scalability, interoperability, and fault tolerance are crucial factors in designing advanced IoT systems.
- Energy efficiency and real-time responsiveness are essential for applications like smart agriculture and health monitoring.
Key Concepts
-
Term: Multilayered Architecture
Definition: A system design that divides responsibilities into layers for improved management, including perception, network, data processing, application, and business layers.
-
Term: ServiceOriented Architecture (SOA)
Definition: An architectural pattern that promotes the use of services (e.g., data storage, device management) often hosted on cloud or edge environments for interoperability.
-
Term: Scalability
Definition: The ability of an IoT system to support a growing number of devices and users without performance loss, achieved through techniques like distributed computing.
-
Term: Interoperability
Definition: The capability of diverse IoT devices and platforms to communicate and function together, facilitated by standards and protocols such as MQTT and CoAP.
-
Term: Fault Tolerance
Definition: The ability of an IoT system to continue operating smoothly in the event of a failure, commonly implemented through redundancy and failover systems.
-
Term: Lowpower Design
Definition: Design strategies that emphasize energy efficiency in IoT devices, such as using energy-efficient communication protocols and duty-cycling.
-
Term: Realtime Responsiveness
Definition: The immediate action response of IoT systems, often prioritized by using real-time operating systems (RTOS) to minimize delay.
