[Tinyos-help] help a question about the signal strength and transmission distance

2006-08-04 Thread Yinying Yang
   I am wondering how to use the signal strength to compute the distance   between the sender and the receiver. I think there should be some   relationship between the RSSI and the transmission range. Is there any    formula about this or any tool can be used in TOSSIM?    Thank you.    Yinying Yan

Aside from the actual ad-hoc networking, I think this is (or was) the main research topic for motes. I only have one ref for you but it may have enough key words to get Google to cough up more: http://www.cs.berkeley.edu/~kamin/pubs/whitehouse02calamari.pdf As far as TOSSIM is concerned I don

hi.rssi and link physical distance are related in a complex way. It depends on the absortion of microwaves in the enviroment. http://www.cs.berkeley.edu/~kamin/pubs/whitehouse02calamari.pdfAs far as TOSSIM is concerned I don't think power setting and received strength are implemented, so simul
