10、s specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on
11、 them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of I
12、TU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is u
13、sed for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with t
14、he Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required o

ITU-T H.641 (02/2012) Introduction Ubiquitous sensor network (USN) is a conceptual network built over existing physical networks that makes use of sensed data and provides knowledge services to anyone, anywhere and at any time, and where
23、the information is generated by using context awareness ITU-T Y.2221. One of the basic infrastructures of USN is wireless sensor networks that monitor physical or environmental conditions. These sensor networks may use different MAC/PHY protocols and different transport protocols, they may have diff
24、erent sensor node identification schemes and may use different management protocols. From the viewpoint of a sensor network management protocol, each sensor network may use different sensor network management protocols that are optimized for its MAC/PHY characteristics, transport layer characteristi
25、cs and for each sensor network management information base (MIB). For example, an IEEE 802.15.4 based sensor network can deliver a 128 bytes frame at one time including 22 bytes of the IEEE 802.15.4 header. It means that a sensor network management protocol for an IEEE 802.15.4-based sensor network
26、should be designed considering this frame size. The ZigBee sensor network based on IEEE 802.15.4 uses its own addressing scheme and defines its own MIB. Currently, many new sensor networking technologies are under development and it is inevitable that optimized sensor networking technologies for a p
27、articular purpose will be deployed. This means that there will be many heterogeneous sensor networks. From the viewpoint of network management, managing each heterogeneous sensor network with heterogeneous management protocols is impractical and an integrated management protocol for all heterogeneou
28、s sensor networks is needed. The common management information protocol (CMIP) ITU-T X.711 is widely used in network management systems. However, most TCP/IP devices only support SNMP. SNMP is favoured and strongly supported by vendors, and it has been successfully adapted to manage wired and wirele
29、ss networks. Due to the limited computing and communication power of sensor networks, the use of standard SNMP in sensor networks is either impractical or impossible. Rec.

A sensor network gateway communicates with sensor nodes using a sensor network specific management protocol. Specific sensor ne
47、twork management protocols for specific sensor networks are out of the scope of this Recommendation. A sensor network gateway has dual network interfaces and performs MAC/PHY protocol translation, transport protocol translation, and management protocol translation between TCP/IP network and specific
48、 sensor networks if necessary. The translation of management protocol means translation between SNMP and sensor network specific management protocols. Protocol translations, other than management protocol translation, are out of the scope of this Recommendation. 7 Functional entities of SNMP-based s
