management framework

7.1 SNMP manager

An SNMP manager is a set of management applications that monitor and control network elements
such as the sensor network gateway and sensor network elements such as sensor nodes. An SNMP
manager uses standard SNMP. Because the sensor network gateway is a normal TCP/IP device, an
SNMP manager can manage the sensor network gateway using standard SNMP.

7.2 SNMP agent
An SNMP agent is a set of software modules that reside in network elements. It collects and stores
management information such as the number of error packets received by a network element. In this
framework, the SNMP agent has two roles, a role as the standard SNMP agent for managing the
sensor network gateway and another role of delivering SNMP commands to the application level
gateway (ALG) and SNMP responses to the SNMP manager.

7.3 Sensor network management protocol manager
A sensor network management protocol manager is a set of management applications that monitor
and control sensor network elements. It receives commands from an ALG and delivers these
commands to the sensor network management protocol agent and receives responses from the
sensor network management protocol agent and delivers these responses to the ALG.
