Study Notes

Three-Layer IoT Architecture

Composed of three essential layers: Perception, Network, and Application.
Application Layer: Offers services and performs semantic analysis to support data usage.
Network Layer: Responsible for routing received data to various distant applications.
Perception Layer: Focuses on collecting information and transmitting data from devices.

Five-Layer IoT Architecture

Extends the three-layer model into five distinct layers: Object, Object Abstraction, Service Management, Application, and Business.
Business Layer: Involves creating business models, flow charts, and graphical representations.
Application Layer: Similar to the three-layer model but also focuses on generating analytic reports.
Service Management Layer: Handles information processing and stores data in databases.
Network Layer: Manages switching and routing, reliable data transmission, and protocol translations.
Perception Layer: Includes smart objects for information collection and data transmission.

Six-Layer IoT Architecture

Comprises six layers for a more complex system: Competence Business, Infrastructure, Application, Transmission, Cognizance, and Focus.
Competence Business Layer: Analyzes business models for improved decision-making.
Infrastructure Layer: Engages with cloud and big data resources for data storage and processing.
Application Layer: Focuses on the categorization of received information.
Transmission Layer: Ensures secure data transmission from sensors to the application layer.
Cognizance Layer: Involved in the collection of sensing information from various sources.
Focus Layer: Responsible for identifying smart objects within IoT systems.

Seven-Layer IoT Architecture

Consists of seven layers which include: Things, Edge Computing, Data Accumulation, Data Abstraction, Application, Collaboration and Processes.
Collaboration and Processes Layer: Emphasizes people and business process interactions.
Application Layer: Works on analytics and report generation for informed decision-making.
Data Abstraction Layer: Combines data from various sources and creates application-oriented schemas for data viewing.
Data Accumulation Layer: Collects data from network packets and stores it in databases.
Edge/Fog Layer: Engages in data filtration, aggregation, analysis, and inspection of packet content.
Connectivity Layer: Focuses on switching, routing, data generation, reliable data transmission, and protocol translation.
Things Layer: Deals with data generation and conversion of data to signals for further processing.
