FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,
in liaison with ISO and IEC, also take part in the work.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and ISO cannot be held responsible for the way in which they are used
or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC and ISO National bodies undertake to apply IEC and
ISO documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO are not
responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication, use of, or reliance upon, this ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC document may be the subject of
patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.
10) The managed objects need to highlight specifically throughout this document. Therefore, the managed objects in
this document are highlighted with italic font style.
ISO/IEC 30142-2 has been prepared by subcommittee 41: Internet of Things and Digital Twin,
of ISO/IEC joint technical committee 1: Information technology. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
JTC1-SC41/288/FDIS JTC1-SC41/296/RVD

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1, available at www.iec.ch/members_experts/refdocs
and www.iso.org/directives.
In order to highlight specifically the managed objects in this document, the managed objects
are written in italics throughout this document.
A list of all parts in the ISO/IEC 30142 series, published under the general title Internet of
Things (IoT) – Underwater acoustic sensor network (UWASN) – Network management system,
can be found on the IEC website.

IMPORTANT – The "colour inside" logo on the cover page of this document indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

INTRODUCTION
Water covers approximately 70 % of the surface of the Earth. Modern technologies introduce
new methods to monitor the body of water, such as pollution monitoring and detection.
Underwater data gathering techniques require exploring the water environment, which can be
most effectively performed by underwater acoustic sensor networks (UWASNs). Applications
developed for the UWASNs can record underwater climate, detect and control water pollution,
monitor marine biology, discover natural resources, detect pipeline leakages, monitor and find
underwater intruders, perform strategic surveillance, and so on.
To build and apply the UWASN technology, most suitable methods for managing the network
have been developed based on the ISO/IEC 30140 series. This document describes the network
management outline and requirements appropriate to the UWASN under the constraints of an
underwater physical environment.
