Internet of Things Architecture

Information Services allow querying, changing and

adding information about the thing in question, while

interaction services enable direct interaction with the

thing by accessing the Resources of the associated

Devices. Resolution is based on a priori knowledge.

Resource Heterogeneous, generally system-specific, software
components that store or process data or information
about one or more Physical Entities, or that provide
access to measurements and actuations in the case of
Sensors and Actuators respectively.

Internal

RFID ―The use of electromagnetic or inductive coupling in the
radio frequency portion of the spectrum to
communicate to or from a tag through a variety of
modulation and encoding schemes to uniquely read the
identity of an RF Tag.‖

[ISO/IEC 19762]

Sensor Special Device that measures physical characteristics
of one or more Physical Entities.

Internal

Service Platform-independent computational entity that can be
used in a platform-independent way.

Internal

Stakeholder (also
referred to as
system
stakeholder)

―An individual, team, or organization (or classes

thereof) with interests in, or concerns relative to, a

system.‖

[IEEE- 1471 - 2000]

Storage Special type of Resource^ that stores information
coming from Resources and provides information about
Entities. They may also include Services to process the
information stored by the Resource. As Storages are
Resources, they can be deployed either on-device or in
the network.

Internal

System ―A collection of components organized to accomplish a
specific function or set of functions.‖

[IEEE- 1471 - 2000]

Tag Label or other physical object used to identify the
Physical Entity to which it is attached.

Internal

Thing Generally speaking, any physical object in combination
with its digital representation. In other words, it denotes
the same concept as an Augmented Entity.

Internal

User A Human or some Active Digital Artefact that is
interested in interacting with a particular physical
object.

Internal

View ―The representation of a related set of concerns. A view
is what is seen from a viewpoint. An architecture view
may be represented by a model to demonstrate to
stakeholders their areas of interest in the architecture.
A view does not have to be visual or graphical in
nature‖.

Viewpoint ―A definition of the perspective from which a view^ is
taken. It is a specification of the conventions for
