12、al 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 committees established by the respective organization to deal with particular fields o

13、f 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 work. In the field of information technology, ISO and IEC have established a joint

14、 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 Standards.

In practice, however, sensor networks have been built and deployed for a relatively small number of applications. This is partly due to the lack of a business c

19、ase 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 sensors, communications and networking, signal processing, electronics, computing, and cy

20、ber 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 almost scratch every time one wishes to design and deploy a sensor network. Yet, upon closer

21、 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/functional blocks that are used in the architecture.The purpose of the ISO/IEC 29182 serie

22、s 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/remove sensor nodes to/from an existing sensor network.The ISO/IEC 29182 series can be used

23、 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 parts. Brief descriptions of these parts are given next.Part 1 provides a general overview an

24、d 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 from various viewpoints, such as business, operational, system, technical, functional, and log

25、ical 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 information on the interfaces among various entities in the reference architecture.Part 6 provides detai

26、led information on the development of International Standardized Profiles.Part 7 provides design principles for the reference architecture that take the interoperability requirements into account.There are no requirements for compliance in ISO/IEC 29182-1 to ISO/IEC 29182-7. Users should ensure that

27、 the sensor nodes, and the related sensor network, are compliant with the application or deployment governing body.

It also describes the general requirements that are identified for sensor networks.2 Normative referencesT

31、h 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 recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance.The key

32、words “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 vendors implementation must provide the option and the feature can be optionally enabled by the network operator/ser

33、vice provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with the specification.5 Overview of sensor networksA sensor network is a system of spatially distributed sensor nodes interacting with each other and, depending on application, with ICT (Inform

34、ation and Communication Technology) infrastructures, in order to acquire, process, and provide information about the physical world and optionally react to such information.This clause describes sensor networks from a communication perspective and a service provisioning perspective. Figures 1, 2 and

35、 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 Figures 1, 2 and 3 gather information about their physical surroundings and deliver this information to the INTERNATIONAL S

This type of sensor network may be regarded as an ad hoc sensor network.Figure 1 Standalone sensor networkFigure 2 depicts the case where multiple sensor networks, two in th

38、e 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 Interconnected sensor networksFigure 3 depicts sensor networks, two in the case of this figure, which are connected to a backbone

39、 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 reservedBS ISO/IEC 29182-1:2013ISO/IEC 29182-1:2013(E)Figure 3 Sensor networks connected to other networksSensor network applicati

40、ons may require application-layer technologies such as data processing (data integration, data filtering), sensor information description and presentation. Data are acquired by sensor nodes and either processed within the sensor network (e.g. sensor nodes in the sensor network) or by service provide

41、rs 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 service providers, as in Figure 3.As for service provisioning, sensor network services may be provided either by a sensor node

42、 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 right 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 par

43、t 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 negotiation of the service to be provided. In some cases, a user that requests services from a sensor node may be integrated wit

44、h that sensor node.6 Characteristics of sensor networks6.1 GeneralWired or wireless sensor networks have unique characteristics which differentiate them from traditional data networks. Sensor networks not only perform data transmission but also perform data acquisition, data processing, data aggrega

45、tion, data management, network management, resource management, automation (sensing and actuation), and other functions and services.Clause 6 identifies the unique characteristics of sensor networks which differentiate from traditional networks.6.2 Service provisioning for individual requirementsSen

46、sor network applications and services allow arbitrary and evolving types and grouping of users. For example, weather information may be provided to consumers such as tourists and fishermen as well as business partners such as airlines, shipping companies and travel agencies. Functions and services p

47、rovided 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 29182-1:2013ISO/IEC 29182-1:2013(E)Users service requirements and expectations may be diverse and change depending on circumstances. Users ma

48、y ask for weather information from a service providing such information, however they may have different requirements depending on their circumstances and applications.A tourist is content with getting summary weather information once or twice a day for the short period of his/her vacation.A fisherm

49、an, 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.A national centre for the study of the climate and weather patterns would need very detailed weather-related information from a wide array of sensors at high sampling r
