Defining the IoT

Posted on Posted in Networks and Security, Uncategorized

The following definitions are reflect sources identified within three principal documents: (1) the DoD’s Policy Recommendations for the IoT; (2) IEEE’s “Toward a Definition of Internet of Things (IoT)”, which is heavily referenced therein; and (3) GAO’s Report to Congressional Committees on the “Internet of Things: Enhanced Assessments and Guidance Are Needed to Address Security Risks in DoD“.  This article is simply intended as a reference page that reflects a sample of definitions most relevant to the Department of Defense.  Because a secondary intention was to generate a word-cloud reflecting the content of these definitions, some of the language has been adjusted.  Original sources are provided, and these are sorted in ascending order by year.  Happy reading!

 

The Internet of Things…

  • Is the building of a global infrastructure for RFID tags

Sean Dodson:
“The Internet of Things”, 2003

 

  • Has the potential to change the world, just as the Internet did
  • If we had computers that knew everything there was to know about things – using data they gathered without any help from us – we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best
  • We need to empower computers with their own means of gathering information, so they can see, hear and smell the world for themselves, in all its random glory. RFID and sensor technology enable computers to observe, identify and understand the world—without the limitations of human-entered data

Kevin Ashton:
“That ‘Internet of Things’ Thing”, 2009

 

  • Is a future network vision comprised of three elements – sensors, tags, and communication/processing capacity
  • Is available anywhere, anytime, by anything and anyone
  • Is a global infrastructure for the information society enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving, interoperable information and communication technologies
  • Is a vision with technological and societal implications

International Telecommunication Union (ITU):
“Ubiquitous Sensor Networks” 2008
“Global Standards Initiative” 2012

 

  • Is the communication between two or more entities that do not necessarily need any direct human intervention
  • Its services intend to automate decision and communication processes
  • Is collectively made up of an increasing number of everyday machines and objects are now embedded with sensors or actuators, are connected through Machine-to-Machine (M2M) communications interfaces, and have the ability to communicate over the Internet

ESTI:
“Machine to Machine”, 2010
“Internet of Things”, no date

 

  • Will connect objects around us (electronic, electrical, non-electrical) to provide seamless communication and contextual services provided by them. Development of RFID tags, sensors, actuators, mobile phones make it possible to materialize IoT which interact and co-operate each other to make the service better and accessible anytime, from anywhere

  • Is a system where the Internet is connected to the physical world via ubiquitous sensors

OASIS:
“Open Protocols”, 2014

 

  • (Small Environment)
    • Is a network that connects uniquely identifiable things to the Internet. The things have sensing/actuation and potential programmability capabilities. Through the exploitation of unique identification and sensing, information about the ‘Thing’ can be collected and the state of the ‘Thing’ can be changed from anywhere, anytime, by anything.
  • (Large Environment)
    • Envisions a self-configuring, adaptive, complex network that interconnects things to the Internet through the use of standard communication protocols. The interconnected things have physical or virtual representation in the digital world, sensing/actuation capability, a programmability feature and are uniquely identifiable. The representation contains information including the thing’s identity, status, location or any other business, social or privately relevant information. The things offer services, with or without human intervention, through the exploitation of unique identification, data capture and communication, and actuation capability. The service is exploited through the use of intelligent interfaces and is made available anywhere, anytime, and for anything taking security into consideration.

IEEE:
“Towards a Definition of IoT”, 2015

 

  • Is a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
  • Has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS) and the Internet.
  • Has been most closely associated with machine-to-machine (M2M) communication in manufacturing and power, oil and gas utilities. Often, products built with M2M communication capabilities are referred to as being smart (smart label, smart meter, smart grid sensors).
