An air monitoring system to measure environmental factors in a wireless sensor network
MinHwan Ok · 2008
In this paper a form of sensor network is operated to monitor air-contamination in subway stations. The system covers both field-based monitoring and infrastructure monitoring. For some sort of sensor componets consumes energy excessively, the recent sleep scheduling approach is employed to save energy of the nodes. The sensor network server congregates data gathered on schedule, and provide environmental information. Reducing energy consumption rate is the practical concern in developing the monitoring system.
