4. WAPMS: THE PROPOSED AIR POLLUTION MONITORING SYSTEM
The proposed wireless sensor network air pollution monitoring system (WAPMS) comprises of
an array of sensor nodes and a communications system which allows the data to reach a server.
The sensor nodes gather data autonomously and the data network is used to pass data to one or
more base stations, which forward it to a sensor network server.
The system send commands to
the nodes in order to fetch the data, and also allows the nodes to send data out autonomously.
Figure 4 shows the architecture diagram of WAPMS.
