    Study Notes

    Introduction to IoT

    • Over 9 billion devices are currently connected to the internet.
    • 20 billion devices are projected to be connected to the internet in the near future.
    • The internet of things (IoT) connects devices, machines, and tools to the internet via wireless technologies.

    Origin of the Terminology

    • The term "Internet of Things" was introduced in 2005 by the International Telecommunication Union (ITU) in their report titled, "The Internet of Things."
    • The report identified the concept of M2M (Machine-to-Machine) connectivity networks, where common household devices could connect to the internet.
    • The report identified RFID, nanotechnology, sensors, and smart networks as IoT enablers.

    Alternate Definition

    • Gartner Research defines the internet of things as a network of physical objects embedded with technology that allows them to communicate and sense internal states or external environments.

    Characteristics

    • IoT architecture features an efficient, scalable, and associated design.
    • IoT devices utilize unambiguous naming and addressing protocols.
    • Abundant sleeping nodes, mobile devices, and non-IP devices are included in IoT networks.
    • Intermittent connectivity is a characteristic of IoT networks.

    IoT Market Share

    • Intel data shows substantial IoT market penetration across various industries.

    Areas of IoT Implementation

    • Business/Manufacturing: Real-time supply chain and equipment analytics, robotic machinery.
    • Healthcare: Portable health monitoring, electronic recordkeeping, pharmaceutical safeguards.

    IoT Enablers

    • IoT networks leverage technologies like Machine-to-Machine (M2M) communication, Cyber-Physical-Systems (CPS), and the Web-of-Things (WoT).

    Connectivity Layers

    • IoT networks use various connectivity layer technologies, including 3G, 4G, 5G, Low Power Wide Area Network (LPWAN), and satellite networks.

    Baseline Technologies

    • M2M communication, CPS, and WoT are closely related and influential technologies for IoT development.

    IoT vs. M2M

    • M2M refers to communication and interactions between machines and devices.
    • M2M interactions can occur via a cloud computing infrastructure.
    • M2M focuses on device management and data collection.
    • M2M was introduced by telecommunications service providers, emphasizing interactions through telcom networks.
    • M2M is a subset of IoT with standards playing a significant role within the IoT landscape.

    IoT vs. WoT

    • WoT allows developers to access and control IoT resources and applications using web technologies.
    • WoT development utilizes RESTful principles and REST APIs.
    • Building a global WoT presents challenges in scalability, security, and other areas.
    • WoT integrates IoT networks with the web, while IoT focuses on broader networking.
    • WoT can be considered an application layer on top of the IoT network layer.
    • IoT includes systems and applications not accessible through the web, such as conventional wireless sensor networks and radio-frequency identification (RFID) systems.

    Terminological Interdependence

    • M2M, CPS, and WoT are key concepts contributing to the overall development and application of the IoT.

    • IoT, M2M, CPS, and WoT play distinct yet interconnected roles in the evolution of connected devices and the broader digital landscape.
