[Tinyos-help] "lossy module" in tinyos 2.0.1

[eamin_winfor at 126.com]

hi alls
 
I'm working with Tinyos 2.0.1, now i meet some problems  about  "lossy model"  in Tossim.
 
The problems i face are:
 
1. My teacher tell me there is a "lossy model" in Tinyos 1.x, and this model can control  the packet loss rate between two Noes.
 
But in tinyos2.0.1, i can't find it in Tossim.  And what should i do  if i want to set the packet loss rate.
 
2. how can i transform the  "gain value of the link "( such as -70.0dbM) to the packet loss rate between two nodes.
 
Any help is appreciated.
 
Best regards.
 
Eamin
