Introduction to IoT

  • IoT is a network of connected things (devices, objects, items) providing intelligent computing services.
  • Smart Things facilitate daily tasks efficiently.
  • IoT advances communication among people.
  • ICT (Information and Communication Technologies) are crucial in modern societies.
  • IoT aims to connect things using network technologies.

What is IoT?

  • IoT encompasses technologies like pervasive computing, sensor technology, embedded systems, and communication technologies (including sensor networking, Internet protocols).
  • This combination underpinning the economic growth of modern societies.
  • The core concept of IoT is ubiquitous connectivity among things and humans.

IoT as a Concept

  • IoT's core idea can be represented as a combination of elements (e.g., Any Time, Any Device, Any Thing, Any Where, Any Network, Connectivity, Convergence, Any Context).
  • IoT introduces a third dimension ("Thing”) to the ICT plane concerning place and time, boosting the communication between humans and things.

IoT Concept Evolution

  • The concept of ubiquitous computing started in the early 1980s with a connected Coke machine at Carnegie Mellon University.
  • The concept of IoT was further developed by scholars like Mark Weiser in 1991 (ubiquitous computing, pervasive computing).
  • Bill Joy (1999) explored device-to-device communication frameworks.
  • Kevin Ashton promoted the term "Internet of Things" in that same year.

Technological Progression in IoT

  • Early internet (1990s) focused on static and dynamic content on the WWW.
  • Web 2.0, large-scale production, and business collaborations led to web services.
  • Smartphones and tablets later introduced social networking apps and enabled further advancement of the IoT with various technologies such as M2M, CPS, WSN, and WoT, allowing communication of things over the internet.

IoT Vision

  • IoT vision can be viewed as "things-centric" and "internet-centric."
  • Things-centric focuses on advancements in "Smart Things."
  • Internet-centric vision involves network technologies enabling smart device interactions and data management.

IoT System Characteristics

  • IoT is a dynamic, distributed network of interconnected smart things that provide information to the system.
  • Its success relies on advancements in various ICT fields (digital ID, communication, networking, computing, and distribution systems).

IoT as Convergence of Three Paradigms

  • IoT is the union of "things-oriented," "network-oriented," and "semantic-oriented" core visions.
  • "Thing" identification (e.g., EPC), smart sensor networks.
  • "Internet" protocols (e.g., IPSO) and interaction between devices and the Internet.
  • "Semantic" data handling (IoT devices generating large amounts of data).

IoT Definitions

  • Various organizations (IEEE, OASIS, NIST, ISO, IETF, ITU) have presented their own definitions of IoT.
  • Common themes include intelligent interaction, interconnected objects and systems, and processing information from both physical and virtual worlds.

IoT Characteristics

  • IoT systems are characterized by (scalability, connectivity, device heterogeneity, and security).
  • Data from sensors and devices is collected, analyzed, and used.
  • Sensor data is vital to improving business workflows.
  • Connectivity through internet and communication infrastructure is essential.
  • Interoperability of various devices across different platforms (using ambient intelligence) is key to intelligent interaction.
  • Scalability of IoT systems is vital as numbers of connected devices increase.
  • Security is paramount, requiring protection of devices and data at all relevant levels (networks, individual devices).

Advantages & Disadvantages of IoT

  • Advantages: improved comfort, convenience, faster and more accurate interactions between devices, automation of daily activities, and optimizing resource use.
  • Disadvantages: challenges regarding interoperability and compatibility of heterogeneous devices, the inherent complexity (resulting in more frequent failures), risks of rising unemployment, and security and privacy concerns.
