Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 29182 consists of the following parts, under the general title Information technology — Sensor

Introduction
A wide range of applications has been proposed for sensor networks. In practice, however, sensor
networks have been built and deployed for a relatively small number of applications. This is partly due
to the lack of a business case for certain applications and partly due to technical challenges in building
a non-trivial sensor network of reasonable complexity. The main reason for this impediment is multi-
disciplinary expertise – such as sensors, communications and networking, signal processing, electronics,
computing, and cyber security – is required to design a sensor network. Presently, the design process
is so complex that one can leverage little from one sensor network design to another. It appears as if
one has to start from almost scratch every time one wishes to design and deploy a sensor network. Yet,
upon closer inspection, there are many commonalities in instantiations of sensor networks that realize
various applications. These commonalities include similarities in the choice of network architecture and
the entities/functional blocks that are used in the architecture.
The purpose of the ISO/IEC 29182 series is to
— provide guidance to facilitate the design and development of sensor networks,
— improve interoperability of sensor networks, and
— make sensor networks plug-and-play, so that it becomes fairly easy to add/remove sensor nodes
to/from an existing sensor network.
The ISO/IEC 29182 series can be used by sensor network designers, software developers, and service
providers to meet customer requirements, including any applicable interoperability requirements.
The ISO/IEC 29182 series comprises seven parts. Brief descriptions of these parts are given next.
ISO/IEC 29182-1 provides a general overview and the requirements for the sensor network reference
architecture.
ISO/IEC 29182-2 provides definitions for the terminology and vocabulary used in the reference
architecture.
ISO/IEC 29182-3 presents the reference architecture from various viewpoints, such as business,
operational, system, technical, functional, and logical views.
ISO/IEC 29182-4 categorizes the entities comprising the reference architecture into two classes of
physical and functional entities and presents models for the entities.
This part of ISO/IEC 29182 provides detailed information on the interfaces among various entities in the
reference architecture.
ISO/IEC 29182-6 provides detailed information on the development of International Standardized Profiles.
ISO/IEC 29182-7 provides design principles for the reference architecture that take the interoperability
requirements into account.
There are no requirements for compliance in the ISO/IEC 29182 series. Users should ensure that
the sensor nodes, and the related sensor network, are compliant with the application or deployment
governing body.

5 SN interfaces overview
A sensor network (SN) is a system consisting of interconnected (via wireless or wired) and spatially
distributed sensor nodes to acquire, process, transfer, and provide information from the physical world
and optionally react to the physical world by using an actuator or actuators.
Sensor networks have many different applications in a variety of domains such as environment
monitoring, logistics management, industrial automation, intelligent highway system, and perimeter
protection. From one SN application domain to another, significant differences exist in service
requirements, service types, processing functions, interfaces, operational attributes and so on. These
significant differences influence the structure, construction and performance of a SN.
An interface is the shared border between two interactive entities or modules, so interface definition
depends on the entities or modules on both sides. An interface can be described in physical or logical form.
The purpose of developing generic and generalized definitions for SN interfaces is to promote the
interoperability among modules within a sensor node, between sensor nodes, and other entities. Defining
a set of standard interfaces for SN is one of the most efficient approaches to bring the interoperability
to sensor networks.
To provide service and implement application in sensor network, sensor nodes and other entities
have to exchange messages containing sensor data or command. The messages pass through different
functional layers in each entity, and pass from one entity to another.
