Power consumption is the most important metric in
wireless sensor network research, but existing tools for measuring
or estimating power consumption are either impractical or have
unclear accuracy. We present a practical simulation-based tool
for network-scale power estimation based on experience with
Contiki's built-in power profiling mechanism, the COOJA sensor
network simulator and the MSPSim sensor node emulator. We
quantify the accuracy of the tool by comparing simulation results
with experimental testbed results.
