Greg is correct TOSSIM doesn't support any of the CC2420 interfaces. TOSSIM doesn't support changing the power levels. However you can simulate networks with varying densities, link qualities, etc. This is done via altering the link gain model you feed into TOSSIM. Determining what link gain models to use is an exercise left to the reader.
Greg, also mentioned Avrora which has preliminary MicaZ support. Your mileage may vary, it looks like a fairly early beta.
