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. 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. 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.
