international standards and facilitates world trade by providing common standards
between nations [12]. ISO standards help businesses increase productivity while
minimizing errors and waste. By enabling products from different markets to be
directly compared, they facilitate companies in entering new markets and assist in
the development of global trade regularly. The standards also serve to safeguard
consumers and the end users of products and services, ensuring that certified
products conform to the minimum standards set internationally.
ETSI
The European Telecommunications Standards Institute (ETSI) is an independent,
not-for-profit, standardization organization in the telecommunications industry in
Europe, headquartered in Sophia Antipolis, France, with worldwide projection [13].
ETSI deals with telecommunications, broadcasting, and other electronic communications networks and services. ETSI is a European Standards Organization
supporting European regulations and legislation through the creation of harmonized
European standards. Only standards developed by the three ESOs (Cen, Cenelec,
and ETSI) are recognized as European Standards (ENs). ETSI is a member of 3GPP
which develops specifications for advanced mobile communications including 5G
as well as oneM2M which develops specifications for the most efficient deployment
of machine-to-machine communications systems.
IETF
The Internet Engineering Task Force (IETF) is an open organization which develops
and promotes voluntary Internet standards, in particular, the standards that comprise
the Internet protocol suite (TCP/IP) [14]. The IETF is organized into a large number
of working groups and informal discussion groups, each dealing with a specific topic
and operates in a bottom-up task creation mode, largely driven by these working
groups [15]. IETF standards are named Request For Comments (RFC) or Internet
Draft.
3.2.4 IoT Network Standards and the Simplified ISO/OSI
Model
In recent years, many standardization bodies and industrial alliances have proposed
new standards or adapted a previous one for IoT scenarios. A standard is a set of
recommendations regarding communication functions belonging to one or more
layers explained in Sect. 3.2.2. Therefore a possible way to present and compare
them is showing their coverage of the Simplified ISO/OSI Model as done in Fig. 3.8.
