|Internet of Things: Strategic Research Roadmap
|“Internet of Things (IoT) is an integrated part of Future Internet and could be defined as a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and virtual ‘things’ have identities, physical attributes, and virtual personalities and use intelligent interfaces, and are seamlessly integrated into the information network. In the IoT, ‘things’ are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information ‘sensed’ about the environment, while reacting autonomously to the ‘real/physical world’ events and influencing it by running processes that trigger actions and create services with or without direct human intervention. Interfaces in the form of services facilitate interactions with these ‘smart things’ over the Internet, query and change their state and any information associated with them, taking into account security and privacy issues." - Full Text|

|Internet of Things in 2020 - Roadmap for the future
By INFSO D.4 NETWORKED ENTERPRISE & RFID INFSO G.2 MICRO & NANOSYSTEMS
|“Things having identities and virtual personalities operating in smart spaces using intelligent interfaces to connect and communicate within social, environmental, and user contexts”
A different definition, that puts the focus on the seamless integration, could be formulated as: “Interconnected objects having an active role in what might be called the Future Internet”
The semantic origin of the expression is composed by two words and concepts: “Internet” and “Thing”, where “Internet” communication protocol, the Internet suite (TCP/IP)”, while “Thing” is “an object not precisely identifiable” Therefore, semantically, “Internet of Things” means “a world-wide network of interconnected objects uniquely addressable, based on standard communication protocols” - Full Text

From the National Intelligence Council NIC
|“Internet of Things” to refer to the general idea of things, especially everyday objects,that are readable, recognizable, locatable, addressable, and/or controllable via the Internet—whether via RFID, wireless LAN, wide-area network, or other means.Everyday objects includes not only the electronic devices we encounter everyday, and not only the products of higher technological development such as vehicles and equipment,but things that we do not ordinarily think of as electronic at all—such as food, clothing,and shelter; materials, parts, and subassemblies; commodities and luxury items;landmarks, boundaries, and monuments; and all the miscellany of commerce and culture." - Full Text|

|Vision and Challenges for Realising the Internet of Things
CERP-IoT Edited by Harald Sundmaeker Patrick Guillemin Peter Friess and Sylvie Woelfflé
|The Internet of Things links the objects of the real world with the virtual world, thus enabling anytime, any place connectivity for anything and not only for anyone. It refers to a world where physical objects and beings, as well as virtual data and environments, all interact with each other in the same space and time.|
|IETF - The Internet of Things - Concept and Problem Statement
Gyu Myoung Lee, Jungsoo Park, Ning Kong, Noel Crespi
|"The basic idea is that IoT 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."
|Future Internet Report
By UK Future Internet Strategy Group
|"An evolving convergent Internet of things and services that is available anywhere, anytime as part of an all-pervasive omnipresent socio–economic fabric, made up of converged services, shared data and an advanced wireless and fixed infrastructure linking people and machines to provid eadvanced services to business and citizens."|
|From the Internet of Computers to the Internet of Things
By Friedemann Mattern and Christian Floerkemeier
|"The Internet of Things represents a vision in which the Internet extends into the real world embracing everyday objects. Physical items are no longer disconnected from the virtual world, but can be controlled remotely and can act as physical access points to Internet services."
"The use of the word “Internet” in the catchy term “Internet of Things” which stands for the vision outlined above can be seen as either simply a metaphor – in the same way that people use the Web today........or it can be interpreted in a stricter technical sense, postulating that an IP protocol stack will be used by smart things (or at least by the “proxies”, their representatives on the network)."
|Intelligent Products in Autonomous Logistics
By Farideh Ganji, Ernesto Morales Kluge and Bernd Scholz-Reiter
|"IoT can be understood as an enabling framework for the interaction between a bundle of heterogeneous objects and also as a convergence of technologies."|
By Society for brain integrity in Sweden
|"It means that any physical thing can become a computer that is connected to the Internet and to other things. IoT is formed by numerous different connections between PCs, human to human, human to thing and between things. This creates a self-configuring network that is much more complex and dynamic than the conventional Internet. Data about things is collected and processed with very small computers (mostly RFID tags) that are connected to more powerful computers through networks."|

|The Internet of Things: Networked objects and smart devices
By Hammersmith Group
|"The Internet of Things comprises a digital overlay of information over the physical world. Objects and locations become part of the Internet of Things in two ways. Information may become associated with a specific location using GPS coordinates or a street address. Alternatively, embedding sensors and transmitters into objects enables them to be addressed by Internet protocols, and to sense and react to their environments, as well as communicate with users or with other objects."|
|The Internet of Things (With Registration)
By McKinsey Quarterly
|"The physical world itself is becoming a type of information system. In what’s called the Internet of Things, sensors and actuators embedded in physical objects—from roadways to pacemakers—are linked through wired and wireless networks, often using the same Internet Protocol (IP) that connects the Internet."|
|The Internet of Things - How the Next Evolution of the Internet Is Changing Everything
By Cisco IBSG
"IoT is simply the point in time when more “things or objects” were connected to the Internet than people. In 2003, there were approximately 6.3 billion people living on the planet and 500 million devices connected to the Internet. By dividing the number of connected devices by the world population, we find that there was less than one (0.08) device for every person. Based on Cisco IBSG’s definition, IoT didn’t yet exist in 2003 because the number of connected things was relatively small given that ubiquitous devices such as smartphones were just being introduced...........................Refining these numbers further, Cisco IBSG estimates IoT was “born” sometime between 2008 and 2009."

|The Internet of Things: In a Connected World of Smart Objects (pdf)
By: Accenture & Bankinter Foundation of Innovation
|The Internet of Things (IoT) consists of things that are connected to the Internet, anytime, anywhere. In its most technical sense, it consists of integrating sensors and devices into everyday objects that are connected to the Internet over fixed and wireless networks.
A new concept that develops on advances incommunications and IT by applying them to objects,enabling improved interaction. The IoT comprises anetwork of everyday objects interconnected over theInternet.
|"The Internet of Things refers to a virtual representation of a broad variety of objects on the Interent and their integration into Internet or Web based systems and services. Based on interaction and commuication interfaces such as RFID, NFC, barcodes or 2D codes they expose information, features and functionalities which can be integrated into systems and services."|
|Architecting the Internet of Things
By Uckelmann, Dieter; Harrison, Mark; Michahelles, Florian (Eds.)
"A minimalist approach towards a definition may include nothing more than things, the Internet and a connection in between. Things are any identifiable physical object independent of the technology that is used for identification or providing status information of the objects and its surroundings. Internet in this case refers to everything that goes beyond an extranet, thus requiring access to information for more than a small group of people or businesses."
"the future Internet of Things links uniquely identifiable things to their virtual representations in the Internet containing or linking to additional information on their identity, status,location or any other business, social or privately relevant information at a financial or non-financial pay-off that exceeds the efforts of information provisioning and offers information access to non-predefined participants. The provided accurate and appropriate information may be accessed in the right quantity and condition, at the right time and place at the right price. The Internet of Things is not synonymous with ubiquitous / pervasive computing, the Internet Protocol (IP), communication technology, embedded devices, its applications, the Internet of People or the Intranet / Extranet of Things, yet it combines aspects and technologies of all of these approaches." - Full Text (paid book)

|E-Flux: Internet of Things
By Keller Easterling
|"An “internet of things” describes a world embedded with so many digital devices that the space between them consists not of dark circuitry but rather the space of the city itself. The computer has escaped the box, and ordinary objects in space are carriers of digital signals."|
|The Internet of People: Integrating IoT technologies is not a technical problem
|"...is the combination of distributed information processing, pervasive wireless networking and automatic identification, deployed inexpensively and widely. The underlying technologies and the applications that are traditionally discussed don't matter much, because it is this combination of factors that deeply affects people and industries, and it does it by connecting people's immediate experiences to the power of digitally aggregated and analyzed information. In other words, the Internet to Things turns physical actions into knowledge in the cloud and knowledge in the cloud into physical action in a way that's never existed before."|
|Rick Bullotta - Co-Founder/CTO of ThingWorx
**From a Linkedin IoT group discussion April 2010:**
|"The Internet of Things represents the intersection of people (meatspace), systems (cyberspace) and the physical world (atomspace). It represents the "connectedness" of these entities and the range of applications that it enables. It (will someday) represent a set of protocols for interacting with the information shadow (data, event streams) and capabilities (services) of the participants in the internetof things. It (will someday soon) represent a semantic model for the connected entities. It is enabled by and intersects with the ubicompmacro trends. It affects and influences the development of the future internet (a topic we'll be discussing at the International Research Forum in a couple weeks) - the effect on IP addressing, security/packet validity, different types of QOS needs, and higher level protocols could be substantial." - Full Discussion|
|Four Stages in the Internet of Things
By Kevin Kelly
|"I think we can see a fourth stage beyond. That fourth stage is the drift towards linking up the things themselves. You want all the data about a thing to be embedded into the thing. You want location information embedded at, or in, the location itself. You actually want to connect not to the airline's computer, nor to the airline's flight page, nor to the flight data, but to the flight itself. Ideally, we would connect to the embedded processing and raw information in the airplane, in your particular seat, at the airport's slot -- the entire complex of items and services we call "the flight." What we ultimately want is an internet of things." - Full Article|

|Cisco chief futurist: The Internet of Things is here
By Dave Evans Cisco's Chief Futurist
|“My premise here today is we’re seeing the first true evolution of the Internet. Why is that? Partly we’re seeing shift in architectural models. The new Internet, if you will, is becoming more mobile than fixed,” Evans said.
What is the Internet of Things? "At the core of this evolution of the Internet is the idea that the Internet becomes more sensory — more proactive and less reactive. It also takes into account that the world has hit a point where there are more devices connecting to the Internet than people doing so."
