If you are interested in WSN related research, my PhD thesis which I defended in December 2012 is now freely available from the University of Geneva website.
Here is the abstract:
“This thesis explores dierent techniques that can be used to visualize several aspects of Wireless Sensor Networks research. We will present software tools and setups as well as dierent scenarios which benet from our approach. The utility of our visualization techniques as well as having real-time and time-delayed visualization systems will be explored in both simulated wireless sensor networks as well as physical real deployed sensors forming wireless sensor networks.”
