When you enter a modern office building, such as ITU-T’s office in Geneva, it is quite common for the glass doors to open automatically and for lights to come on as you enter a darkened room. This “magic” is achieved by motion sensors. But entering a building in the future, you might be welcomed by name with a personal greeting and given security access suitable to your status (e.g., employee, delegate, newcomer). To do this without human intervention would require not only intelligent sensors but also perhaps ID tags and readers and interaction with a database.

In a new Technology Watch briefing report from ITU-T, the term “Ubiquitous Sensor Networks” (USN) is used to describe networks of intelligent sensor nodes that could be deployed “anywhere, anytime, by anyone and anything”. The technology has huge potential as it could generate applications in a wide range of civilian and military fields, including ensuring safety and security, environment and habitat monitoring, real-time healthcare, landmine detection and intelligent transport systems (ITS).

Sensor nodes may vary enormously in size, cost and complexity. Their characteristics are highly application-specific. Depending on the sensor type, the links between sensors may be provided by either wired or wireless communication. Energy-efficient operation is an important requirement for scenarios where sensor nodes are deployed in hazardous or inaccessible environments.

The variability of USN poses a challenge to researchers and a number of different standards development organizations (SDOs) are already engaged int this field. Within ITU-T, USN standardization is being carried out under the auspices of the Next-Generation Network Global Standards Initiative (NGN-GSI). The new report, the fourth in a series of ITU-T Technology Watch Briefing Reports, describes the different components of USN, notes the standardization work currently going on in ITU-T, and gives an overview of the different fields of applications of USN in both, developed and developing countries.

Max Mosley, the head of Formula One’s governing body, the FIA, calls for accelerated standards development to support ICTs in vehicles for improvements in safety, and the mitigation and monitoring of climate change. Speaking at ITU’s annual Fully Networked Car event at the Geneva Motor Show, Mosley said that the leading edge expertise within F1 to develop “green” technologies could have applications beyond the sport, particularly in the area of fuel efficiency and monitoring of environmental impact. Most F1 teams have as many as 300 channels of information flowing between the cars and the pit crew and as the complexity of systems grow their interconnection will become critical he said.

Dr Hamadoun I. Touré, ITU Secretary-General, reminded participants that the UN Secretary-General, Ban Ki-moon, has called climate change the “moral challenge of our generation”. He said: “With the Fully Networked Car we can provide traffic management, monitoring, and analysis, all of which will help meet the climate change challenge. Those who successfully meet this challenge will end up with a real competitive advantage in world markets.”

Michel Mayer, CEO Freescale Semiconductor, a leading supplier of ICTs to F1 and one of the sponsors of the event, expressed concerns at the proliferation of proprietary standards and called for global standards bodies such as ITU to take a lead. He said that it is critical that further development be standards-driven.

The event also featured a keynote presentation from David Butler, Marketing Director, Honda Racing F1 Team, who emphasised how the powerful brand platform of F1 can present a global environmental message. The Fully Networked Car event had as its centrepiece the new 2008 Honda Racing F1 “Earthdreams” car.

A particular concern, according to experts, is in the areas of telematics and the application of intelligent transport systems (ITS) which participants at the Fully Networked Car agreed offer the best solution for a reduced carbon footprint from the global use of vehicles.

ITU will help to push this standards work and convergence between the ICT and automotive industries with initiatives such as its FITCAR (From/In/To Cars Communication) Focus Group, and the hosting of the Advisory Panel for Standards Cooperation on Telecommunications related to Motor Vehicles (ASPC TELEMOV). Also helping to step up this activity, Malcolm Johnson, ITU’s director of standards, announced that the Fully Networked Car event – already in its fourth year - will now become a regular fixture bringing together the two industries. The 2009 event is planned for 4-6 March. ITU will also be organising two ITU symposia on ICTs and Climate Change: in Kyoto, 15-16 April, hosted by the government of Japan; and in London, 17-18 June, hosted by BT.

Priorities identified for future standardization included: a common set of standards for the full range of nomadic devices; standards for software defined radios; standards to cope with the gap between the short lifecycle of mobile phones compared to the relatively long lifecycle of cars; and privacy, where there is a need for a common understanding about what data is reasonable to collect and retain.

The Fully Networked Car event brought together over 200 experts from the ICT and automotive worlds. It was organised by ITU with the support of ISO and IEC under the World Standards Cooperation (WSC) banner.

ITU experts have reported a good spirit of cooperation following a meeting with counterparts from the Internet Engineering Task Force (IETF) on the topic of T-MPLS, during February’s Study Group 15 meeting in Geneva.

The Ad-Hoc Group on T-MPLS met to iron out perceived inconsistencies between MPLS developed by IETF and T-MPLS developed in ITU-T. The meeting appointed Malcolm Betts as ITU representative and Dave Ward from IETF.

A joint working team (JWT) has been created with experts from ITU-T and IETF.

Previously the IETF requested that the ITU-T either: (1) Work in cooperation to extend the IETF's MPLS technologies through the IETF Standards Process or: (2) Decide to use its own Ethertypes and maintain separation of codepoints in the future, change the name of the technology so it is not easily confused with IETF MPLS and work independently.

The JWT will allow the IETF and ITU-T to work in close collaboration on T-MPLS to understand the implications of these options and facilitate the subsequent development of solutions that ensure that the required degree of MPLS/T-MPLS compatibility, consistency, and coherence, recognizing that the sole design authority for MPLS resides in the IETF, and the domain of expertise for Transport Network Infrastructure resides in ITU-T SG15.

It is expected that the group will use remote collaboration tools and make a decision on which way to progress by April 2008. See also previous newslog entry here.

MPLS is widely embraced in backbone networks as a way to speed up routers. Lately some have advocated its use further downstream in access networks, there have even been suggestions to extend this as far as customer premises. ITU’s work seeks to support this, but additionally to allow the seamless interworking between Ethernet and MPLS. This has been progressed in SG 15 through the completion of a new set of Recommendations for Transport MPLS (T-MPLS), a technology which uses a subset of the components defined in the MPLS Layer Network Architecture of Recommendation G.8110 to support packet transport applications that adhere to ITU-T layer network architecture principles. A T-MPLS layer network can operate independently of its clients and its associated control networks (i.e., multi-carrier or single carrier networks (MCN, SCN) and can carry a variety of client traffic types. This independence affords network operators the freedom necessary to design robust packet transport networks for their own use and to transport customer traffic. T-MPLS is designed to behave consistently with existing transport technologies, thus offering the operational characteristics, performance and reliability that network operators require from carrier-class technologies. The new Recommendations for this technology cover the T-MPLS layer network architecture (G.8110.1/Y.1370.1), interfaces for the T-MPLS Hierarchy (G.8112/Y.1371), and T-MPLS Equipment (G.8121/Y.1381).

Senior technical experts have laid down the gauntlet on energy saving in ICTs following a recent meeting in Geneva.

Following tutorials on power saving, at a recent meeting of ITU-T’s Study Group 15 (SG 15), experts agreed to work towards a proposed percentage reduction of power consumption in broadband technologies. The aim is for the agreed figure to form part of a Resolution from the upcoming World Telecommunication Standardization Assembly (WTSA-08). Reduction of power consumption should and can be done without the degradation of services according to experts. Presentations from the tutorials are available here.

The UN Secretary-General, Ban Ki-moon has also underlined ITU’s role here saying: "ITU is one of the very important stakeholders in the area of climate change." ITU representatives made a statement at the UN Conference on Climate Change in Bali, Indonesia, illustrating how ICTs are both a cause and a potential cure for climate change.

Speaking during the event attended by over 100 representatives from the ICT industry worldwide for each of its three, hour-long sessions, Deputy Secretary-General of ITU, Houlin Zhao expressed appreciation that the meetings had proven so popular at such an early stage of the work. He pointed out that ICTs are responsible for 2.5 per cent of carbon emissions. This is roughly the equivalent of the airline industry and requires our urgent attention, he said.

The issue of power saving will be discussed within the wider context of climate change at Symposia on ICTs and Climate Change, to be held April 15-16 2008 in Kyoto, Japan, hosted by the Ministry of Internal Affairs and Communications (MIC) and 17-18 June 2008 in London, hosted by BT. The events are part of a new initiative by ITU to better understand how ICTs can help mitigate and adapt to climate change as well as monitoring its impact.

Experts speaking at the SG 15 tutorials pointed to inefficiencies in terms of end-device power consumption level compared to the signal power. The deployment of broadband access networks is of particular concern as operators worldwide rollout this new technology that some predict will massively increase power demands.

Some simple measures, for example specifying power saving modes in network terminations such as: ‘asleep’, ‘standby’, as well as ‘on’ and ‘off’, were cited by speakers. It was also noted that next-generation networks (NGN) can lower greenhouse gas emissions by reducing network complexity, and introducing equipment that is more tolerant to natural climatic conditions and therefore does not require air conditioning. Smart buildings, energy supply and transport industries must all play their part in achieving greenhouse gas reductions.

A first and completed task of the ITU experts has been to create a power saving checklist for standards authors. Malcolm Johnson, Director of the Telecommunication Standardization Bureau, ITU congratulated SG 15 for responding so quickly to the request to address climate change. He urged all Study Groups to start the process of reviewing their Recommendations (ITU’s name for standards) according to the new checklist and assign appropriate metrics regarding reduction of greenhouse gases.

The checklist is intended to ensure that standards are drafted taking into account the most economic and energy-efficient solution. It is essentially, a set of questions relating to energy saving in networks. Experts propose that each new ITU-T Recommendation should contain a clause that identifies its impact on climate change and demonstrates ways that it contributes towards emission reduction, covering both production and the use of the equipment.

In order that this work is completed with the highest degree of efficiency there is broad consensus that ITU action has to be taken in partnership with all other bodies working in the field and that everything is done to avoid duplication of work.
