A wireless sensor network (WSN) is a network made of many small computers with onboard sensor boards. The sensor nodes, currently 1-8 cubic centimetres in size, are self-contained units typically consisting of a battery, radio communications, microcontroller, and sensors. The nodes typically self-organize their networks, rather than having a pre-programmed network topology in order to respond better to changes in their environment. Because of the limitations due to battery life, nodes are built with power conservation in mind, and generally spend large amounts of time in a low-power "sleep" mode or processing the sensor data. Examples of major academic centers for research in wireless sensor networks are CITRIS at Berkeley and CENS at UCLA, in the USA and the NCCR MICS at EPFL, in Switzerland.
Visualization of Wireless Sensor Networks Data
The data gathered from wireless sensor networks is usually saved in the form of numerical data in a central base station. There are many programs that help viewing these large ammounts of data like TosGUI and MonSense. Additionally, the Open Geospatial Consortium (OGC) is specifying standards for interoperability interfaces and metadata encodings that enable real time integration of heterogeneous sensor webs into the Internet, allowing any individual to monitor or control Wireless Sensor Networks through a Web Browser.
Center for Embedded Networked Sensing (CENS)
The Center for Embedded Networked Systems (CENS) at the University of California, Los Angeles, directed by Deborah Estrin, is also a leading research center with $40 million in core funding from the National Science Foundation [1].
Center for Information Technology Research in the Interest of Society (CITRIS)
The Center for Information Technology Research in the Interest of Society at the University of California, Berkeley, currently directed by S. Shankar Sastry, is a major center of research and development into wireless sensor networks, and has used them to study microclimate variations in individual redwood trees [2].
National Center of Competence in Research on Mobile Information and Communication Systems (NCCR MICS)
The NCCR MICS was launched in 2001 at EPFL. It is performing research in mobile information and communication systems, with a strong emphasis on wireless sensor networks and novel self-organizing networks and information systems.
