6 Architecture of an SNMP-based sensor network management framework
Figure 1 illustrates the architecture of the SNMP-based sensor network management framework.
The architecture comprises a sensor network manager, sensor network gateway and sensor node.
The sensor network manager resides in the TCP/IP network and manages sensor nodes or sensor
networks through sensor network gateways.

Figure 1 – Architecture of an SNMP-based sensor network
management framework

A sensor network manager communicates with the sensor network gateway using standard SNMP
over the IPv4 or IPv6.

A sensor network gateway communicates with sensor nodes using a sensor network specific
management protocol. Specific sensor network 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 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.
