"Wireless Sensor Network (WSN) for distributed
applications and distributed Information Fusion,
interacting with the physical envionment"


= Wireless sensor network project highlights

AlarmNet - a medical WSN testbed for assisted living. Sensor device
design and implementation for environmental, vital signs, and power
consumption.

LUSTER - a WSN testbed for monitoring the light and growth environment
under shrub thicket on the islands of Eastern Shore of Virginia as part
of the Long-Term Ecological Research (LTER) initative.

ETag is a sensor device designed for the Advanced Health and Disaster
Aid Network (AID-N) project. ETag2 monitors vital signs, including ECG,
oxygen saturation in blood (SpO2), temperature and 3D acceleration.

SeeMote device - A compact, low power, multimodal device with a LCD
screen, user input support, and removable multimedia memory card
(SD/MMC) for local data storage by MicaZ sensor nodes and a software
library for TinyOS that provides a graphical user interface.


= The future of Wireless Sensor Networks

I envision a world of sensor systems that have countless nearly dust-size 
devices monitoring almost every aspect of life. How are these dust-networks 
different from WSN, what new challenges will be there? There was a paradigm 
shift from distributed computing networks to sensor networks. As the multitude 
of small battery powered devices with limited resources became available, 
it appeared that many new applications become available and new problems had 
to be solved, such as localization, power  management, power efficient communication, 
etc. Will the availability of the new, tiny, one cubic millimeter sized sensor nodes 
demand for another paradigm shift because of the differences in the capabilities, 
applications, and resources? What would be the major differences and consequences?
