>From what I can tell, TOSSIM doesn't really emulate any radio hardware
in particular.  It uses a noise model based on empirical data to decide
if packets can be heard, but the "radio" itself is fairly simplistic
(e.g., turning the radio hardware on and off is instantaneous).  None of
the CC2420-specific interfaces are supported, so you can't use
CC2420Packet to adjust the power level.

If you want to simulate an application running on hardware with a CC2420
chip, take a look at Avrora (http://compilers.cs.ucla.edu/avrora/).  As
of last month, Avrora has "preliminary" emulation of MicaZ motes, which
use CC2420 radio hardware.
