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 20005 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology.

Introduction
Sensor networks have been widely deployed in different application domains including environment
monitoring, transportation, manufacturing, chemical process, healthcare, home and buildings, and
many other domains. Wired/wireless sensor networks can be regarded as an extension of the Internet
interfacing the physical world. Intelligent sensor networks are increasingly attractive in a wide range
of applications to meet challenges from intrinsic environment complexity, large orders of magnitude
network scaling and dynamic application requirements. Intelligent sensor networks are developed to
provide new system capabilities such as environment self-adaptability, dynamic task supporting and
autonomous system maintenance. Collaborative information processing (CIP), which closely integrates
information processing algorithms with collaboration mechanisms, is an essential technology enabling
the intelligent sensor networks to enhance efficiency and to improve quality and reliability of information
processing and its outputs in real application scenarios. This standard specifies services and interfaces
supporting CIP in the intelligent sensor networks.

3.6
sensor network
system of spatially distributed sensor nodes interacting with each other and, depending on applications,
possibly with other infrastructure in order to acquire, process, transfer, and provide information extracted
from its environment with a primary function of information gathering and possible control capability
Note 1 to entry: Distinguishing features of a sensor network can include: wide area coverage, use of radio networks,
flexibility of purpose, self-organization, openness and providing data for multiple applications.
[SOURCE: ISO/IEC 29182-2]
3.7
sensor network application
use case of sensor networks, which provide a set of functions to users to meet defined requirements
EXAMPLE Monitoring forests to detect natural fires; monitoring seismic activity; monitoring pollution levels
in environment.
[SOURCE: ISO/IEC 29182-2]
3.8
sensor network service
set of functionalities offered by individual sensor network elements or the sensor network
EXAMPLE generating an alarm signal if the measurement made at a sensor exceeds drops out of certain
prescribed range; providing average sensor measurements over a given geographic area.
[SOURCE: ISO/IEC 29182-2]
3.9
sensor node
sensor network element that includes at least one sensor and optionally actuators with communication
capabilities and associated data processing capabilities
Note 1 to entry: It may include additional application capabilities.
[SOURCE: ISO/IEC 29182-2]
3.10
service set or service subset
