# ISO/IEC JTC 1/WG 7

Note: This working group has been disbanded.
ISO/IEC JTC 1/WG 7 Sensor Networks (WGSN) was a standardization working group of the joint technical committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), which develops and facilitates standards within the field of sensor networks. The international secretariat of ISO/IEC JTC 1/WG 7 is the Korean Agency for Technology and Standards (KATS), located in the Republic of Korea.
Maintenance of the standards was transferred to ISO/IEC JTC 1/SC 41.

## History

ISO/IEC JTC 1/WG 7 was established in October 2009 via Resolution 34 of the 24th JTC 1 Plenary in Tel Aviv. The group was established with the intention of creating an ISO/IEC JTC 1 working group that would develop and facilitate the development of international standards for sensor networks. The working group is the successor of ISO/IEC JTC 1/SGSN, Study Group on Sensor Networks, which was established in 2007, at the 22nd JTC 1 Plenary. All standardization activities and members of ISO/IEC JTC 1/SGSN were transferred to ISO/IEC JTC 1/WG 7 after its establishment.

## Terms of reference

The terms of reference for ISO/IEC JTC 1/WG 7 are:
* In the area of generic solutions for sensor networks, undertake standardization activities that support and can be applied to the technical work of all relevant JTC 1 entities and to other standards organizations. This includes activities in sensor networks such as the following:”
** Standardization of terminology
** Development of a taxonomy
** Standardization of reference architectures
** Development of guidelines for interoperability
** Standardization of specific aspects of sensor networks
* In the area of application – oriented sensor networks, identify gaps and commonalities that may impact standardization activities within the scope of JTC 1. Further, share this information with relevant entities within and outside of JTC 1. Unless better pursued within another JTC 1 entity, the following standardization activities may be pursued as projects by this Working Group:
** Addressing the technology gaps within the scope of JTC 1 entities
** Exploiting technology opportunities where it is desirable to provide common approaches to the use of sensor networks across application domains
** Addressing emerging areas related to M2M and IoT
* In order to foster communication and sharing of information between groups working in the field of sensor networks:
** Seek liaison relationships with all relevant SCs/WGs
** Seek liaison relationships with other organizations outside JTC 1
** Consider the possibility of conducting joint products with relevant ITU-T SGs
** Seek input from relevant research projects and consortia
