Outline
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, use intelligent
interfaces, are seamlessly integrated into the
information network, and often communicate data
associated with users and their environments.
Definition of IoT
Dynamic and self-adapting
Self-configuring
Interoperable communication protocols
Unique identity
Integrated into the information network
Characteristics of IoT
The "Things" in IoT usually refers to IoT devices which have unique
identities and can perform remote sensing and actuating and have
monitoring capabilities.
IoT devices can:
Exchange data with other connected devices and applications
(directly or indirectly), or
Collect data from other devices and process the data locally, or
Send the data to centralized servers or cloud-based application
back-ends for processing the data, or
Perform some tasks locally and other tasks within the IoT
infrastructure, based on temporal and space constraints
Physical Design of IoT
An IoT device may
consist of several
interfaces for
connections to other
devices, both wired and
wireless.
I/O interfaces for
sensors
Interfaces for internet
connectivity
Memory and storage
interfaces
Audio/video interfaces

IoT Protocols
Logical design of an IoT
system refers to an
abstract representation
of the entities and
processes without going
into the low-level
specifics of the
implementation.
An IoT system comprises
a number of functional
blocks that provide the
system the capabilities
for identification,
sensing, actuation,
communication and
management.

RFID technology is used in a number of industries to carry out
various tasks such as:
Asset tracking
Inventory management
Controlling access to confined areas
Personnel tracking
Supply chain management
ID badging
Counterfeit forestalling (e.g., in the pharmaceutical industry)
RFID is also employed in a number of other things:
The keys to unlock your car door;
The automatic deduction of payment while using toll booths;
Building access systems;
Payment cards, student ID cards and even Passports
Wireless sensors & mesh networks.

Connecting these new objects will obviously raise
many questions such as:
the connecting technology of the so-called objects;
the interoperability between objects;
the communication model of these connected
objects;
the possible interaction with the existing models,
such as the Internet;
the choice of the transport model;
the addressing, identifying and naming;
the security and privacy;
the economic impact and the telecommunication
value chain evolution.

IoT Identifiers
In particular, the following classes of IoT identifiers can
be distinguished:
• Object Identifiers (Object IDs), which are used for
uniquely identifying physical or virtual objects.
• Communication Identifiers (Communication IDs), which
are used to identify uniquely devices in the scope of
communications with other devices, including internet-
based communications.
• Application Identifiers (Application IDs), which are
used to identify uniquely applications and services used
in the scope of IoT applications.
