A SWE-Based Network Management Framework for Environment Monitoring

Recently, owing to the attentions of environment issues, the environment monitoring technologies and applications are under rapid development. The research on environment monitoring can be divided into two major aspects: sensing data collection and heterogeneous system integration. With the improvement of sensing devices (e.g., precision, sensing range, Internet connectivity, and computation capability), the operational condition of device is also regarded as the environment information. In this study, an SNMP-based SWE management architecture is proposed. To unite the management of various debris-flow sensors, the entity MIB of debris-flow sensors is defined. Administrator could describe an object and its attributes to construct the tree-based SWE management architecture. This framework provides dynamically managed objects and standardizes the message management between the management system and sensors. Data access and collection are based on SWE standard message format, which is used to enhance exchangeability of sensing data and interoperability of the messages. In the proposed system, the SWE and SNMP services are integrated into Web service based interface, which provides real-time, seamless and remote management services.
