Study Notes

IoT Overview

Internet of Things (IoT) connects the physical world to the internet through sensors, enabling devices to interact intelligently.
Difficult to define due to similarity with peer technologies; IoT encompasses systems where objects communicate with each other and humans.
IoT provides a framework for every object to have a digital representation, facilitating new applications bridging physical and virtual realms.

Key Characteristics

Network available "anywhere, anytime, by anything, and anyone."
Cyber Physical Systems (CPS) connect smart devices across sectors (transportation, energy, manufacturing, healthcare) to improve efficiency and sustainability.
IoT infrastructure includes interconnected objects, people, systems, and intelligent services for processing physical and virtual information.

Scope of "Things"

Diverse "things" include computers, sensors, vehicles, and everyday items (e.g., food, clothes, medicines).
Classified into three categories: people, machines (e.g., sensors), and information (e.g., products).
Unique identification methods are essential for addressing, communication, and identity verification of these "things."

Data Management

Distributed sensors gather environmental data, directing it to the cloud for storage and analysis aimed at enhancing business workflows.
Connectivity enables interaction among physical and virtual objects through established internet infrastructure comprising wired and wireless technologies.

Security and Interoperability

Security measures must be implemented at both network and end-device levels to protect data integrity and privacy.
Device heterogeneity necessitates interoperability across various hardware/nodes, enhanced by smart software architecture for intelligent interactions.
Scalability is crucial as the number of IoT device interactions grows, leading to more device-to-device interactions, reducing the reliance on human input.
