Part 4: Interoperability
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. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
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 National Committees and ISO member bodies.
3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or 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 National Committees and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC 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 publication.
7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC National Committees or ISO member 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 of, use of, or reliance upon, this ISO/IEC
publication or any other IEC, ISO or ISO/IEC publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC publication may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 30140-4 was prepared by subcommittee 41: Internet of Things

Information technology – Underwater acoustic sensor network (UWASN), can be found on the
IEC and ISO websites.
This International Standard has been approved by vote of the member bodies, and the voting
results may be obtained from the address given on the second title page.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION
Water covers approximately 71 % of the surface of the Earth. Modern technologies introduce
new methods to monitor the body of water, for example 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
locate underwater intruders, perform strategic surveillance, and so on.
The ISO/IEC 30140 series provides general requirements, reference architecture (RA)
including the entity models and high-level interface guidelines supporting interoperability
among UWASNs in order to provide the essential UWASN construction information to help
and guide architects, developers and implementers of UWASNs.
Additionally, the ISO/IEC 30140 series provides high-level functional models related to
underwater sensor nodes and relationships among the nodes to construct architectural
perspective of UWASNs. However, the ISO/IEC 30140 series is an application agnostic
standard. Thus, the ISO/IEC 30140 series specifies neither any type of communication
waveforms for use in UWASNs nor any underwater acoustic communication frequencies.
Specifying communication waveforms and/or frequencies are the responsibility of architects,
developers and implementers .
Acoustical data communication in sensor networks necessitates the introduction of acoustical
signals that overlap biologically important frequency bands into the subject environment.
These signals can conflict with regional, national, or international noise exposure regulations.
Implementers of acoustical communication networks should consult the relevant regulatory
agencies prior to designing and deployment of these systems to ensure compliance with
regulations and avoid conflicts with the agencies.
The purpose of the ISO/IEC 30140 series is to provide general requirements, guidance and
facilitation in order for the users of the ISO/IEC 30140 series to design and develop the target
UWASNs for their applications and services.
The ISO/IEC 30140 series comprises four parts as shown below.
• Part 1 provides a general overview and requirements of the UWASN reference
architecture.
• Part 2 provides reference architecture models for UWASN.
• Part 3 provides descriptions for the entities and interfaces of the UWASN reference
architecture.
• Part 4 provides information on interoperability requirements among the entities within a
UWASN and among various UWASNs.

___________
Architects, developers, and implementers need to be aware of the submarine emergency frequency band, near
and below 12 kHz, and it is recommended to provide a provision for such submarine emergency band in their
UWASN design and applications.
