3. 2008/7/3 Introduction  In this paper, we present a sensor network monitoring software, named NanoMon, which has a flexible architecture and supports for various user requirements of sensor network applications  NanoMon employs a widely used database, MySQL, to concurrently and correctly manage sensing data and node information  To show flexibility and adaptability of NanoMon, we implemented two WSN applications- home monitoring and parking lot monitoring systems.

4. 2008/7/3 Introduction  Wireless sensor network (WSN) is a computer network consisting of spatially distributed sensor devices, which collect quite detailed information about the physical environment.  WSNs have made many novel applications  environmental monitoring, home automation, object tracking, security and prevention of disasters.  To deal with sensor network data generated various operating environment, users inevitably require monitoring software.

5. 2008/7/3 Introduction  NanoMon enables users to interpret sensor network status visually by providing decent visualization components for sensor network monitoring  topology, sensor data, sensor list, received packet log.  NanoMon can manage multiple sets of sensor network information and store sensor data related with them.  NanoMon also provides plug-in capability for adding and removing custom components at need.
