A wireless sensor network (WSN) is a network made of thousands of nanocomputers with onboard sensor boards. The sensor nodes, currently the size of a 35 mm film canister, are self-contained units consisting of a battery, RF adapter, microcontroller, and sensor board. The nodes self-organize their networks, rather than having a pre-programmed network topology. 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.
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 [1].
Center for Embedded Networked Sensing (CENS)
The Center for Embedded Networked Sensing, directed by Deborah Estrin, is also a leading research center with $40 million in core funding from the National Science Foundation [2]. Essentially, UCLA and Berkeley are the leaders in the area of wireless sensor networks with a majority of the publications in the cutting-edge field at top conferences and journals.
