If you don't have the facilities to actually measure the power consumption of 
a real mote, use data sheets for the radio, uC, and whatever else is relevant 
to build a model.  Our model turned out to be reasonably close.

There's some useful information regarding various radios and standard motes 
you might find useful here: http://www.tinynode.com/uploads/media/spots.pdf
