11、 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 of technical activity. ISO and IEC technical committe

12、es 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 technical committee, ISO/IEC JTC 1.International St

17、ications has been proposed for sensor networks. 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 case for certain applications and partly due to technical challenges in building a non-trivia

18、l 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 cyber security is required to design a sensor network. Presently, the design process is so com

19、plex 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 inspection, there are many commonalities in instantiations of sensor networks that realize

20、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 series is to provide guidance to facilitate the design and development of sensor networks, improv

21、e 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 by sensor network designers, software developers, and service providers to meet customer re

22、quirements, including any applicable interoperability requirements.The ISO/IEC 29182 series is comprised of seven parts. Brief descriptions of these parts are given next.ISO/IEC 29182-1 provides a general overview and the requirements for the sensor network reference architecture.ISO/IEC 29182-2 pro

23、vides definitions for the terminology and vocabulary used in the reference architecture.ISO/IEC 29182-3 presents the reference architecture from various viewpoints, such as business, operational, system, technical, functional, and logical views.ISO/IEC 29182-4 categorizes the entities comprising the

24、 reference architecture into two classes of physical and functional entities and presents models for the entities.ISO/IEC 29182-5:2013 provides detailed information on the interfaces among various entities in the reference architecture.ISO/IEC 29182-6 provides detailed information on the development

25、 of International Standardized Profiles.ISO/IEC 29182-7 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 are to ensure that the sensor nodes and the

26、 related sensor network are compliant with the application or deployment governing body.

33、tructures, in order to acquire, process, and provide information about the physical world and optionally react to such information ISO/IEC 29182-1.There are many different sensor network applications in a variety of domains such as environment monitoring, logistics management, industrial automation,

34、 intelligent highway system, and perimeter protection. From one sensor network service domain to another, significant differences exist in service requirements, service types, processing functions, interfaces, operational attributes, data formats, and so on. These differences influence the interoper

35、ability of sensor networks.Due to these differences, a sensor network may be classified into two different types of sensor network, a homogeneous sensor network and a heterogeneous sensor network.The differentiation of the homogeneous and heterogeneous sensor networks can be viewed from sensor type

36、perspective and from communication protocol perspective. From the sensor type perspective, the homogeneous sensor networks can be classified as having the same type or functionally identical sensor nodes while the heterogeneous sensor networks can be classified as having different types or functiona

37、lly different sensor nodes. From the communication protocol perspective, the homogeneous sensor networks can be classified as having the same or interoperable protocols while the heterogeneous sensor networks can be classified as having different or not interoperable types of protocols. In this stan

38、dard, the communication protocol perspective is used to differentiate the types of sensor networks.The typical difference is the communication protocol. There are various communication protocols for sensor networks, such as IEEE 802.15.4x series, IETF 6LoWPAN, ZigBee, Bluetooth, and UWB.From the com

39、munication protocol perspective, homogeneous sensor networks are by definition interoperable with each other, because they use the same communication protocol between entities of their service domains. On the other hand, heterogeneous sensor networks are not able to interwork with each other due to

40、the differentiation of the communication protocols they use.Heterogeneity is a common feature of sensor networks, but it may cause various problems. A sensor network application may rely on different sub-networks of a heterogeneous sensor network.Therefore, the interoperability between heterogeneous

41、 sensor networks is a great challenge in the Sensor Network Reference Architecture (SNRA).5.2 Interoperability in sensor network service frameworkFrom a service-oriented viewpoint, the flow of information from sensor nodes to service providers for providing specific sensor network services to users,

42、 the overall architecture of sensor network can be represented in the hierarchical architecture.This hierarchical architecture, which is called the sensor network service framework, is illustrated in Figure 1. It is the same as Figure 7 in ISO/IEC 29182-5. It has been reproduced in this document for

43、 ease of reference.2 ISO/IEC 2015 All rights reservedBS ISO/IEC 29182-7:2015ISO/IEC 29182-7:2015(E)Figure 1 Interfaces and entities of the sensor network service frameworkThere are various communication protocols or interfaces for each entity in Figure 1. Interoperability implies an internetworking

44、capability between the entities in the sensor network service framework. Figure 2 is a graphical representation of an interoperable sensor network service framework with the arrows representing the interfaces that enable seamless interoperability between the entities.Figure 2 Graphical representatio

46、EC 29182-7:2015ISO/IEC 29182-7:2015(E)various cases for the interoperability of sensor networks need to be considered. Figure 3 illustrates the complexity of interoperability within this system of systems.Figure 3 Interoperability of sensor network service framework in detailVarious entities of the

47、sensor network service framework shown in Figure 3 may use different communication technologies, protocols and data formats. Therefore, data flow between various entities must be interoperable.The advantages of interoperability between heterogeneous sensor networks are: Improving sensor network serv

49、ways of maintaining interoperability within the sensor network service framework. Also, It provides guidelines for interoperability.Interoperability can be achieved by a standard development process that promotes open architectures and a standardization of interfaces between subdivisions (both subsystems and sensor networks), layered structures in sensor networks and its applications. For the reference architecture to fulfill the requirements of interoperability, existing interoperability standards should
