[Tinyos-help] [Broadcast and tree graph]

[vazoumana fofana]

It s not really the distance but the  minimal number of hops until the sink. 
the mote just keep its  minimal cots of hops until the sink. I don t use 
TOSSIM. i experiment under real conditions. This is the sink who collect all 
motes' positions and can deduce a graph of id mote.
Thanks
