Hi Phil,
I present PowerTOSSIM, a power modeling extension to TOSSIM. PowerTOSSIM
accurately models power consumed by TinyOS applications. I also include a
detailed model of the power consumption of the Mica2 motes.
TOSSIM uses an old version of the mica radio stack, which does not support
power management and tuning transmission power. PowerTOSSIM includes a port
of the mica2 radio stack, so it is now possible to run programs that take
advantage of the CC1000's power management features. To use it include in
Makefile:
PFLAGS += -I%T/platform/pc/CC1000Radio
PowerTOSSIM web: http://www.eecs.harvard.edu/~shnayder/ptossim/
