Remote Monitoring of Air-Quality over Internet

We have systematically studied the architecture and infrastructure of air-quality remote monitoring systems. This architecture consists of monitoring controllers, monitoring agents, MNIB (MoNitor Information Base), protocols and the Internet. We describe air-quality monitoring systems in 4 models, i.e., organization model, information model, communication model, and functionality model. The information model deals with monitoring information structure and MNIB. The basic unit of monitoring information is a monitored object with 6 attributes. MNIB takes a tree-like structure and its leaves store a monitored object. The communication model discusses how the monitoring information is communicated between monitoring controllers and monitoring agents. We devise a proprietary network application layer protocols, termed as ARMP (Air-quality Remote Monitor Protocol), dedicated to air-quality remote monitoring systems. ARMP operates in four modes, i.e., monitor, monitor-next, set and trap. We have designed the message format for ARMP.
