Internet of Things Architecture

Entity of Interest
(EoI)

Any physical object as well as the attributes that

describe it and its state that is relevant from a user or

application perspective. The term is obsolete in the IoT-

A reference model: the term Physical Entity should be

used instead

Internal

Gateway A Gateway is a forwarding element, enabling various
local networks to be connected.
Gateways can be implemented in Device that provides
protocol translation between peripheral trunks of the
IoT that are provided with lower parts of the
communication stacks. For efficiency purposes,
gateways can act at different layers, depending on
which is the lowest layer in a common protocol
implementation. Gateways can also provide support for
security, scalability, service discovery, geo-localisation,
billing, etc.

Internal

Global Storage Storage that contains global information about many
entities of interest. Access to the global storage is
available over the Internet.

Internal

Human A Human that either physically interacts with Physical
Entities or records information about them, or both.

Internal

Identifier (ID) Artificially generated or natural feature used to
disambiguate things from each other. There can be
several IDs for the same PhysicalEntity. This set of IDs
is an attribute of a PhysicalEntity.

Internal

Identity Properties of an entity that makes it definable and
recognizable.

Information Model ―An Information Model^ is a representation of concepts,
relationships, constraints, rules, and operations to
specify data semantics for a chosen domain of
discourse. The advantage of using an Information
Model is that it can provide sharable, stable, and
organized structure of information requirements for the
domain context.
The Information Model is an abstract representation of
entities which can be real objects such as devices in a
network or logical such as the entities used in a billing
system. Typically, the Information Model provides
formalism to the description of a specific domain
without constraining how that description is mapped to
an actual implementation. Thus, different mappings can
be derived from the same Information Model. Such
mappings are called data models.‖

Infrastructure
Services

Specific services that are essential for any IoT

implementation to work properly. Such services provide

support for essential features of the IoT.
