According to my knowledge of how TOSSIM models radio, there is no such
notion of "signal strength". One way I can think of "emulating" signal strength
in TOSSIM is through bit-error-rate (higher error rate for weaker signals).
However, dynamically changing the bit-error-rate during simulation will require a more detailed understanding of the bit-level radio model code in TOSSIM. (majorly: rfm_model.h rfm_model.c)
Another way to emulate it would be trying to flip a bit before sending it out. You can define the probability of a bit being flipped according to the signal strength you are using. This might be easier without going into the rfm_model.* code.

Hi,
how do I control the signal strength used to transmit in TOSSIM ? Pot can be used for mica and rene motes in an indirect way, but I am looking for a way to do it for simulation on a pc.
Thanks
