Is it because CC2420 only provides packet-level interface, that's why there's no CC2420 simulation implementation? So how energy efficient is the hardware implemented MAC in CC2420? Does it mean there's no B-MAC in CC2420?

There is currently no CC2420 simulation implementation: TOSSIM uses a
packet simulation. The micaz TOSSIM platform simulates the atm128
timers down to the HPL (registers), but active messages use a
simulation-specific implementation.
