I did a paper studying the ability of RSSI on MICA2's to predict
distance between sensor motes: 600,000+ samples across 6
environments. You can find it here:
http://www.winmee.org/2005/papers/WiNMee_Ault.pdf
I also have a Master's thesis on the same topic, but it's quite a bit
longer and considerably more boring :).
We found that you can't do much better than an accuracy of about +/-
30 feet. Time difference of arrival is a much better choice, at
least over a short range (i.e. http://cricket.csail.mit.edu).

There is code, someplace, that measures the time difference
between an audio ping and a radio message. I'm sorry that I
don't know where it is right now though. There's also a bunch
of simulation work using radio signal strengths, but again
I'm no use as a concrete pointer. Maybe these ideas are enough
to start a google search...

Hello,
How can I get to estimate the distance between motes in a network??
I need to build the table of the neighbors for each mote, but I
don´t know how ...?
Can anybody help me, please?
