Hi all,
I can't seem to figure out how to model lossless environment in Tossim, i.e.
100% packet delivery rate and error-free. I've searched the archives and
found a few messages on this subject, but they all refer to Tinyos-1.x. I am
using Tinyos-2
Thanks,

I imagine the best way is in the link specification. Tutorial 11 talks a
little about this.
The method you're looking for is:
*
add(src, dest, gain)*: Add a link from *src* to *dest* with *gain*. When *
src* transmits, *dest* will receive a packet attenuated by the *gain* value.

Hi Chad,
Thanks for quick response!
That's what I've been doing too, but I still have weird inconsistencies. My
grid network initializes and builds routing tree perfectly about 9 out of 10
times, but that one time some node somewhere never gets the message sent to
it.
I am thinking it must be
You're right even with a gain of 0 you'll still have the possibility of a
collision.
I might suggest looking into using the BinaryInterferenceModelC.nc instead
of the UscGainInterferenceModelC.nc. You'll need to use a different
ActiveMessageC.nc.
Cheers

Hi,
I am facing a similar problem on TOSSIM on tinyos 1.x. I have used the
LossyBuilder to generate a grid topology. Say there are four nodes 0 to 3. A
message sent by node 0 is not received by 1, 2, and 3 at the same time. There
are instances that a message that is broadcasted by 0 is not
