12、 ISO (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 comm

13、ittees 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

14、work. 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

15、Standards. 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 el

17、20005:2013(E) Introduction Sensor networks have been widely deployed in different application domains including environment monitoring, transportation, manufacturing, chemical process, healthcare, home and buildings, and many other domains. Wired/wireless sensor networks can be regarded as an extens

18、ion of the Internet interfacing the physical world. Intelligent sensor networks are increasingly attractive in a wide range of applications to meet challenges from intrinsic environment complexity, large orders of magnitude network scaling and dynamic application requirements. Intelligent sensor net

19、works are developed to provide new system capabilities such as environment self-adaptability, dynamic task supporting and autonomous system maintenance. Collaborative information processing (CIP), which closely integrates information processing algorithms with collaboration mechanisms, is an essenti

20、al technology enabling the intelligent sensor networks to enhance efficiency and to improve quality and reliability of information processing and its outputs in real application scenarios. This standard specifies services and interfaces supporting CIP in the intelligent sensor networks. ISO/IEC 2013

41、ks have to meet the challenges from intrinsic environment complexity, large orders of magnitude network scaling and dynamic application requirements. Environmental self-adaptability: An intelligent sensor network shall adapt to obtain required system performances if the physical environment of the s

42、ensor networks monitoring area changes. For example, an intelligent sensor network based anti-intrusion system should guarantee consistent system performances such as detection and false alarming rate (FAR) when the environment in which the sensor network is deployed changes. Dynamic task supporting

43、: An intelligent sensor network shall support dynamic tasking including dynamic task assignment, dynamic task ordering by prioritization, dynamic service provisioning for information users/consumers, and dynamic quality of service (QoS) adjustment. Autonomous system maintenance: An intelligent senso

44、r network shall autonomously maintain system functionalities in case of network scaling, node mobility, new node entrances, node exits, and node failures. 5.3 Overview of collaborative information processing The key differences between traditional telecommunication infrastructures and information se

45、rvice systems based on sensor networks are that (1) sensor networks systems collect raw sensory data from physical world; and (2) from these data, extract application-specific information in order to obtain feature level data, decision level information, and knowledge about the physical world. Integ

46、rated with metadata such as sensory information description, sensor identification, and sensory information location, CIP handles efficient resource management to provide the dynamic tasking to fulfil the requests demanded by information service consumers. Though different sensor network application

47、s normally require application-specific services, the collaborative processing is an indispensable requirement for senor network based information service to handle constraints in power (e.g. batteries), computing resources, storage, and communication bandwidth. The collaborative processing also has

48、 to deal with technical challenges such as task dynamics, measurement uncertainty, node mobility, and environmental adaptation ability. The aims of CIP in sensor networks are to improve system efficiency, enhance quality of service, and guarantee system performance. It provides efficient mechanisms

49、such as majority-voting fusion, decision template fusion and statistical methods for handling incomplete and/or inaccurate information. It also provides protocols to meet challenges from intrinsic environment complexity, large orders of magnitude network scaling and dynamic application requirements. CIP can be viewed from three distinct viewpoints.
