This Wireless Sensor Network Data Visualization Framework tries to be a tool for the visualization and analysis of data collected by a wireless sensor network in a generic scope of application. It also tries to establish a sensor network control interface. The tool will include several facilities to treat sensor network data. It allows ht e generation of evolution charts, interpolation maps, evolution data videos, and report generation. It also includes modules to add external data not collected by nodes, but related to the network conditions. Node management will be possible thanks to the execution of commands in network nodes, to perform changes in network operation. All these functionalities have been implemented taking into account a reasonable performance level. It also guarantees reliability making use of security restrictions. The tool will be easily maintainable and will allow the portability between different hardware platforms, both regarding to the platform in which it will be executed and network node hardware, allowing data management and data treatment of different platforms. © 2008 ACM.
