12、SO (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 commit

13、tees 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 wo

14、rk. 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 St

15、andards. 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 elem

In practice, however, sensor networks have been built and deployed for a

19、 relatively small number of applications. This is partly due to the lack of a business case for certain applications and partly due to technical challenges in building a non-trivial sensor network of reasonable complexity. The main reason for this impediment is multi- disciplinary expertise such as

20、sensors, communications and networking, signal processing, electronics, computing, and cyber security is required to design a sensor network. Presently, the design process is so complex that one can leverage little from one sensor network design to another. It appears as if one has to start from alm

21、ost scratch every time one wishes to design and deploy a sensor network. Yet, upon closer inspection, there are many commonalities in instantiations of sensor networks that realize various applications. These commonalities include similarities in the choice of network architecture and the entities/f

22、unctional blocks that are used in the architecture. The purpose of the ISO/IEC 29182 series is to provide guidance to facilitate the design and development of sensor networks, improve interoperability of sensor networks, and make sensor networks plug-and-play, so that it becomes fairly easy to add/r

23、emove sensor nodes to/from an existing sensor network. The ISO/IEC 29182 series can be used by sensor network designers, software developers, and service providers to meet customer requirements, including any applicable interoperability requirements. The ISO/IEC 29182 series are comprised of seven p

24、arts. Brief descriptions of these parts are given next. Part 1 provides a general overview and the requirements for the sensor network reference architecture. Part 2 provides definitions for the terminology and vocabulary used in the reference architecture. Part 3 presents the reference architecture

25、 from various viewpoints, such as business, operational, system, technical, functional, and logical views. Part 4 categorizes the entities comprising the reference architecture into two classes of physical and functional entities and presents models for the entities. Part 5 provides detailed informa

26、tion on the interfaces among various entities in the reference architecture. Part 6 provides detailed information on the development of International Standardized Profiles. Part 7 provides design principles for the reference architecture that take the interoperability requirements into account. Ther

27、e are no requirements for compliance in ISO/IEC 29182-1 to ISO/IEC 29182-7. Users should ensure that the sensor nodes, and the related sensor network, are compliant with the application or deployment governing body.

28、rmation technology Sensor networks: Sensor Network Reference Architecture (SNRA) Part 1: General overview and requirements 1 Scope This part of ISO/IEC 29182 provides a general overview of the characteristics of a sensor network and the organization of the entities that comprise such a network. It a

29、lso describes the general requirements that are identified for sensor networks. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the re

30、ferenced document (including any amendments) applies. ISO/IEC 29182-2, Information technology Sensor networks: Sensor Network Reference Architecture (SNRA) Part 2: Vocabulary and terminology 3 T erms a nd definiti ons For the purposes of this document, the terms and definitions given in ISO/IEC 2918

31、2-2 apply. 4 Conventions In this part of ISO/IEC 29182: The keywords “is required to” indicate a requirement which must be strictly followed and from which no deviation is permitted if conformance to this document is to be claimed. The keywords “is recommended” indicate a requirement which is recomm

32、ended but which is not absolutely required. Thus this requirement need not be present to claim conformance. The keywords “can optionally” and “may” indicate an optional requirement which is permissible, without implying any sense of being recommended. These terms are not intended to imply that the v

33、endors implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification. 5 Overview of sensor networks A sensor network is a sys

34、tem of spatially distributed sensor nodes interacting with each other and, depending on application, with ICT (Information and Communication Technology) infrastructures, in order to acquire, process, and provide information about the physical world and optionally react to such information. This clau

35、se describes sensor networks from a communication perspective and a service provisioning perspective. Figures 1, 2 and 3 illustrate from a communication perspective the overall architecture and logical arrangements of components in three classes of sensor networks. The sensor networks shown in Figur

36、es 1, 2 and 3 gather information about their physical surroundings and deliver this information to the INTERNATIONAL ST ANDARD ISO/IEC 29182-1:2013(E) ISO/IEC 2013 All rights reserved 1BS ISO/IEC 29182-1:2013ISO/IEC 29182-1:2013(E) sensor network user(s), and any of the communications links may be i

37、mplemented using wired or wireless technologies: there is no constraint in principle on mixing communications technologies within a network. Figure 1 depicts a standalone sensor network that operates on its own and is isolated from other networks. This type of sensor network may be regarded as an ad

38、 hoc sensor network. Figure 1 Standalone sensor network Figure 2 depicts the case where multiple sensor networks, two in the case of this figure, are interconnected via a gateway. Gateways can play various roles in a sensor network, as shown in Figures 1 and 2 and shortly in Figure 3. Figure 2 Inter

39、connected sensor networks Figure 3 depicts sensor networks, two in the case of this figure, which are connected to a backbone network or other entities. In this case, gateways provide sensor networks with connectivity to other networks possibly through access networks.2 ISO/IEC 2013 All rights reser

40、vedBS ISO/IEC 29182-1:2013ISO/IEC 29182-1:2013(E) Figure 3 Sensor networks connected to other networks Sensor network applications may require application-layer technologies such as data processing (data integration, data filtering), sensor information description and presentation. Data are acquired

41、 by sensor nodes and either processed within the sensor network (e.g. sensor nodes in the sensor network) or by service providers connected to the sensor networks, as in Figure 1 and Figure 2. Alternatively it can be transferred, through a backbone network, to applications and other entities such as

42、 service providers, as in Figure 3. As for service provisioning, sensor network services may be provided either by a sensor node directly or by a service provider. Users may request services, without an intermediary, from an arbitrary or a designated sensor node, as in the case of the users on the r

43、ight side of Figure 1 and 2 or from a service provider, as in the case of the users on the left side of Figure 1, the middle part of Figure 2 and the right side of Figure 3. A service provider gathers sensor data either from sensor networks directly or through a backbone network and facilitates the

44、negotiation of the service to be provided. In some cases, a user that requests services from a sensor node may be integrated with that sensor node. 6 Characteristics of sensor networks 6.1 General Wired or wireless sensor networks have unique characteristics which differentiate them from traditional

45、 data networks. Sensor networks not only perform data transmission but also perform data acquisition, data processing, data aggregation, data management, network management, resource management, automation (sensing and actuation), and other functions and services. Clause 6 identifies the unique char

46、acteristics of sensor networks which differentiate from traditional networks. 6.2 Service provisioning for individual requirements Sensor network applications and services allow arbitrary and evolving types and grouping of users. For example, weather information may be provided to consumers such as

47、tourists and fishermen as well as business partners such as airlines, shipping companies and travel agencies. Functions and services provided by sensor networks may be quite diverse supporting many applications, market segments and types of users. ISO/IEC 2013 All rights reserved 3BS ISO/IEC 29182-1

48、:2013ISO/IEC 29182-1:2013(E) Users service requirements and expectations may be diverse and change depending on circumstances. Users may ask for weather information from a service providing such information, however they may have different requirements depending on their circumstances and applicatio

49、ns. A tourist is content with getting summary weather information once or twice a day for the short period of his/her vacation. A fisherman, on the other hand, may need periodic weather updates throughout the day as well as warnings for inclement weather conditions as soon as they become available. He would need such weather information for the duration of the fishing season. The crewmen of a ship travelling on high seas may request extended weather forecasts for the duration of their trip.
