ITU-T F.747.2 (06/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunication

8、s, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications

9、on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid

10、down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunicati

11、on administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandat

12、ory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws at

13、tention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or oth

14、ers outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

24、defined elsewhere: 3.1.1 climate change b-IPCC: Climate change refers to a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or long

25、er. Climate change may be due to natural internal processes or external forcings, or to persistent anthropogenic changes in the composition of the atmosphere or in land use. Note that the Framework Convention on Climate Change (UNFCCC), in its Article 1, defines climate change as: a change of climat

26、e which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods. The UNFCCC thus makes a distinction between climate change attributable to human activiti

27、es altering the atmospheric composition, and climate variability attributable to natural causes. 3.1.2 greenhouse gas b-ISO 14064-1: Gaseous constituent of the atmosphere, both natural and anthropogenic, that absorbs and emits radiation at specific wavelengths within the spectrum of infrared radiati

ITU-T F.747.2 (06/2012) 3.1.3 sensor ITU-T Y.2221: An electronic device that senses a physical condition or chemical compound and delivers an electronic signal proportional to the observed characteristic. 3.1.4 sensor network ITU-T

29、Y.2221: A network comprised of interconnected sensor nodes exchanging sensed data by wired or wireless communication. 3.1.5 sensor node ITU-T Y.2221: A device consisting of sensor(s) and optional actuator(s) with capabilities of sensed data processing and networking. 3.1.6 ubiquitous sensor network

30、ITU-T Y.2221: A conceptual network built over existing physical networks which make use of sensed data and provide knowledge services to anyone, anywhere and at any time, and where the information is generated by using context awareness. 3.1.7 USN middleware ITU-T Y.2221: A set of logical functions

35、 tiers for estimating GHG emissions from fossil fuel combustion: The tier 1 method is fuel-based, since emissions from all sources of combustion can be estimated on the basis of the quantities of fuel combusted (usually from national energy statistics) and average emission factors. Tier 1 emission f

36、actors are available for all relevant direct greenhouse gases. The tier 2 method is estimated from similar fuel statistics as used in tier 1, but country-specific emission factors are used in place of the tier 1 defaults. This is because different specific fuels, combustion technologies or even indi

37、vidual plants may produce different country-specific emission factors. The tier 3 method uses either detailed emission models or measurements and data at an individual plant level where appropriate. Properly applied, these models and measurements should provide better estimates, primarily for non-CO

38、2 greenhouse gases, though at the cost of more detailed information and effort. The tier 3 method allows an enterprise to measure real GHG emissions to avoid overestimation that may happen due to the conservativeness principle. In the latter, conservative assumptions, values and procedures are used

39、when data and assumptions are uncertain and the cost of measures to reduce uncertainty is not worth the increase in accuracy. Conservative accounting results for GHG emissions are more likely to be overestimated than underestimated. Enterprises may install a local GHG monitoring network at their pla

40、nt level. 7 Analysis of environmental impact by USN applications and services 7.1 Deployment elements of USN ITU-T Y.2221 defines USN as a conceptual network and an information infrastructure that delivers sensed information and knowledge services to anyone, anywhere and at any time. In USNs, inform

41、ation and knowledge are developed by using context-aware techniques. USN applications and services are established by integration of sensor network services into a network infrastructure. They can be applied to everyday life in an invisible way as everything is virtually linked by pervasive networki

42、ng between users (including machine and human) and sensor nodes, and relayed through intermediate networking entities such as application servers, middleware entities, access network entities, and USN gateways. Integration of the hardware, 4 Rec. ITU-T F.747.2 (06/2012) software, USN applications an

43、d USN services can be used in many civilian application areas such as industrial automation, home automation, agricultural monitoring, healthcare, environment, pollution and disaster surveillance, and security.

45、y technology to mitigate climate change by monitoring diverse environmental data and enabling energy consuming sources to be controlled according to the environmental data. Sensor nodes can measure and deliver different types of environmental data, such as, pressure, humidity, temperature, light, ch

46、emicals, strain and tilt, speed and acceleration, magnetic fields, vibrations, motion, metal detection and sound. The sensing parameters are used to trace climate change and to understand climate phenomena. The issues are how to deliver the sensed data and how to manage, present and exploit the data

47、 to derive value-added information for countering climate change. This clause briefly introduces examples of how USNs are applied to mitigate climate change. 7.2.1 Direct climate change monitoring USN applications and services provide direct monitoring for the acquisition of climate data. For exampl

48、e, marine environment monitoring and glacier status monitoring help trace continuous environmental changes. In order to help counter climate change, it is important to monitor the climate to verify if changes to the environment are caused by human influence or natural phenomena. The use of sensor ne

49、tworks to monitor the climate has been researched for decades; this has allowed the development of viable technology and techniques for monitoring climate change. It has been proved with many experiments, that USN-based monitoring systems give valuable data. Marine environment monitoring shown in Figure 3 is an example of direct environment monitoring. The data of the sensor nodes used to monitor the real-time status of the marine and glacier environment are transmitted to the local monitoring and management system
