[Tinyos-help] no implementation in /platforms/micaz/chips/cc2420/sim/SimCC2420C.nc in Tinyos-2.x

[Liu Haibin]

Then is there any plan to implement CC2420 simulation? How accurate is the
current packet level simulation?

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?

Haibin
