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
12、 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

17、5ISO/IEC 29182-7:2015(E) Introduction A wide range of applications 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 p
18、artly 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 cyber security is required to design
19、 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 inspection, there are many common
20、alities 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 series is to provide guidance to facil
21、itate 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 by sensor network designers, so
22、ftware developers, and service providers to meet customer requirements, 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
23、 the sensor network reference architecture. ISO/IEC 29182-2 provides 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 logic
24、al views. ISO/IEC 29182-4 categorizes the entities comprising the 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 architectur
25、e. ISO/IEC 29182-6 provides detailed information on the development 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
26、to ISO/IEC 29182-7. Users are to ensure that the sensor nodes and the related sensor network are compliant with the application or deployment governing body.

33、ributed sensor nodes interacting with each other and, depending on applications, with ICT infrastructures, 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
34、a variety of domains such as environment monitoring, logistics management, industrial automation, intelligent highway system, and perimeter protection. From one sensor network service domain to another, significant differences exist in service requirements, service types, processing functions, inter
35、faces, operational attributes, data formats, and so on. These differences influence the interoperability 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 d
36、ifferentiation of the homogeneous and heterogeneous sensor networks can be viewed from sensor type 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 nod
37、es while the heterogeneous sensor networks can be classified as having different types or functionally 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 n
38、etworks can be classified as having different or not interoperable types of protocols. In this standard, 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 s
39、ensor networks, such as IEEE 802.15.4x series, IETF 6LoWPAN, ZigBee, Bluetooth, and UWB. From the communication protocol perspective, homogeneous sensor networks are by definition interoperable with each other, because they use the same communication protocol between entities of their service domain
40、s. On the other hand, heterogeneous sensor networks are not able to interwork with each other due to 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 differen
41、t sub-networks of a heterogeneous sensor network. Therefore, the interoperability between heterogeneous sensor networks is a great challenge in the Sensor Network Reference Architecture (SNRA). 5.2 Interoperability in sensor network service framework From a service-oriented viewpoint, the flow of in
42、formation from sensor nodes to service providers for providing specific sensor network services to users, 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 illustrat
43、ed in Figure 1. It is the same as Figure 7 in ISO/IEC 29182-5. It has been reproduced in this document for 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 framework There are various com
44、munication protocols or interfaces for each entity in Figure 1. Interoperability implies an internetworking 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 representin
45、g the interfaces that enable seamless interoperability between the entities. Figure 2 Graphical representation of an interoperable sensor network service framework Interoperability also needs to exist vertically so that information may be exchanged seamlessly within the hierarchical structure of the
46、 sensor networks supporting a complex system of systems. Therefore, ISO/IEC 2015 All rights reserved 3BS ISO/IEC 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 sy
47、stem of systems. Figure 3 Interoperability of sensor network service framework in detail Various entities of the 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 interope
48、rable. The advantages of interoperability between heterogeneous sensor networks are: Improving sensor network service scalability Extending sensor network functionality Reusability Potential cost and development/implementation time reduction Interchangeability of components for ease of maintenance a
