[Avrora] TinyDB energy consumption

are you using the same scenario as described in the paper?
Furthermore, please be aware that the table just describes the expected
power consumption based on guessing the active cpu time. I expect that in
reality (e.g. in Avrora) the active cpu time turns out to be less and so it
consumes less energy.
Can you send the detailed trace?
Please also compare the powerTossim (SenSys 04) result to yours...
Hope this helps,
