Specialist Task Force 447:
GeoNetworking media-dependent functionality for ITS-G5

Who we are:

Team Leader: Jan de Jongh, TNO,
Team Members:
Jérôme Haerri, Eurecom,
Katrin Sjöberg, Volvo,
Dieter Smely, Kapsch,
Tessa Tielert, KIT,

What we do:

The proposed action of the STF aims at the development of the standard for GeoNetworking media-dependent functioning for ITS G5 (TS 102 636-4-2) and will provide recommendations (change requests) to other standards. For the ETSI TS 102 636-4-2 standard development, the work includes in particular the specification of network-layer DCC and network-layer support for multi-channel operation of ITS-G5. For the recommendations/change request, the action should develop suggestions for other standards developed in TC ITS WGs 2, 3 and 4 in order to resolve dependencies of these standards with the GeoNetworking standards series.

For more details, see our Terms of Reference

Why we do it:

The proposed action will allow the finalization of the last critical part of the relevant series of standards for GeoNetworking and is an important part to successfully execute the mandate M/453 and improve the overall set of standards developed by ETSI TC ITS. The overall GeoNetworking series represents the major part of the standards for the ITS Network and Transport Layer and is an important step towards the finalisation of the overall minimum set of standards..

The proposed action will complete the series of networking and transport protocols for ad hoc communication with ITS-G5. The completion of the series is a requirement for the deployment and market introduction of the system.

ETSI TC ITS: The tasks will be executed by TC ITS (Intelligent Transport Systems), which is the ETSI lead technical body. TC ITS is responsible for the development and maintenance of the standards, specifications and other deliverables to support the development and implementation of ITS Service provision across the network, for transport networks, vehicles and transport users, including interface aspects and multiple modes of transport and interoperability between systems, but not including ITS application standards, radio matters, and EMC.

ETSI Clusters: Recently ETSI has created Technology Clusters to group standardisation work around a set of technology domains such as Internet of Things, Transport, Wireless Technologies, etc. Each cluster groups the relevant ETSI Technical Bodies with related Standards Partners (including Fora), research partners and applicable mandates. It summarises the current (standardisation) work, but also identifies new areas of work and activities. The intention is to enable collaborative efforts within clusters as well as across clusters. They are also a valuable dissemination tool to identify the key areas of ETSI standardisation. This project will liaise with the Transport Cluster.

FP7 Projects: This project will take into consideration the result of completed EC projects FP7 GeoNet, InterSafe-II, PRE-DRIVE C2X. It will work closely with the EC projects ecoMove and DRIVE C2X. The cooperation with the field trial project DRIVE C2X is particularly important as it prepares and conducts Field-Operational Tests (FOTs) on cooperative systems and is associated with various national field test projects across Europe, such as simTD in Germany, SCOREF in France, and also in Italy, Spain, Sweden and Finland.

How we do it:

The work will be carried out by an ETSI Specialist Task Force (STF) under the responsibility of TC ITS.

The TC ITS Chairman and TC ITS/WG 3 Chairman will monitor the progress of the day-to-day work and no steering committee is planned other than the TC ITS plenary meetings and the specific TC ITS/WG3 meetings.

The work will be undertaken both at joint meetings (mostly in Sophia Antipolis at ETSI headquarters) and by teleconferences / Skype session support.

The STF will be supported by a number of ETSI members who are prepared to voluntarily contribute to the drafting of the technical report as well as performing reviews of the STF deliverables for approval in the working group and technical body.

The STF will report to ETSI TC ITS/WG3 (generally by conference call / e-mail but with physical meetings being held in conjunction with some ETSI TC ITS/ WG3 meetings, and, most importantly, ETSI TC ITS Plenary meetings).

In order to achieve its goals, STF447 is equipped with the combined expertise on

  • Networking and transport protocols, in particular ad hoc networking and specifically GeoNetworking,
  • IEEE 802.11 standards and its ITS-specific extensions for DCC and multi-channel operation,
  • Wireless and mobile communication systems and protocols,
  • ITS architecture and cross-layer optimization,
  • General ITS standardization,
  • European projects on cooperative ITS.


The proposed action has two main deliverables:

  • To produce one base standard in the GeoNetworking standard series, i.e. the media-dependent functionality of GeoNetworking for ITS-G5, ETSI TS 102 636-4-2.
  • To analyze other standards of the Minimum Set of Standards in M/453, which have interdependencies with the GeoNetworking standards series and develop recommendations (change requests) in order to resolve the dependencies among these standards.

Time plan:

For STF447, the following Work-Breakdown Structure applies:

  • Task 1: Establish the STF project
  • Task 2: Start of work and development of Table of Content and Scope
  • Task 3: Network-layer congestion control (31 October)
  • Task 4: Preliminary draft #1 TS 102 636-4-2 in WG3 (30 November)
  • Task 5: Network-layer multi-channel operation support (28 February 2013)
  • Task 6: Preliminary draft #2 TS 102 636-4-2 in WG3 (31 March 2013)
  • Task 7: Recommendations for other standards (Phase 1) (28 February 2013)
  • Task 8: Interim report to the EC / EFTA (31 March 2013)
  • Task 9: Completion of TS 102 636-4-2 (31 May 2013)
  • Task 10: Stable draft of TS 102 636-4-2 in WG3 (31 July 2013)
  • Task 11: Final draft of TS 102 636-4-2 for TB approval (31 August 2013)
  • Task 12: Publication of TS 102 636-4-2 (31 October 2013)
  • Task 13: Recommendations for other standards (Phase 2) (31 October 2013)
  • Task 14: Final report to EC/EFTA (31 October 2013)
  • Task 15: General management of STF (continuous)

The STF leader will manage the STF, prepare reports, organize working sessions and meetings, liaise with WG3, etc. in agreement with the ITS/WG3 chairman.
