Key Concepts

Multilayered Architecture

A system design that divides responsibilities into layers for improved management, including perception, network, data processing, application, and business layers.

ServiceOriented Architecture (SOA)

An architectural pattern that promotes the use of services (e.g., data storage, device management) often hosted on cloud or edge environments for interoperability.

Scalability

The ability of an IoT system to support a growing number of devices and users without performance loss, achieved through techniques like distributed computing.

Interoperability

The capability of diverse IoT devices and platforms to communicate and function together, facilitated by standards and protocols such as MQTT and CoAP.

Fault Tolerance

The ability of an IoT system to continue operating smoothly in the event of a failure, commonly implemented through redundancy and failover systems.

Lowpower Design

Design strategies that emphasize energy efficiency in IoT devices, such as using energy-efficient communication protocols and duty-cycling.

Realtime Responsiveness

The immediate action response of IoT systems, often prioritized by using real-time operating systems (RTOS) to minimize delay.
