Energy efficiency is one of the most important requirements for wireless sensor networks. Therefore, it is important to have accurate measurements of the energy consumption of the nodes in a network. We propose an measurement approach capable to handle this issue. In the development of wireless sensor network applications simulators are often used to verify the correctness of the application. Simulators as PowerTOSSIM are further capable to simulate the energy consumption. Doubtless, such energy simulator can be of great benefit, but their accuracy is an important issue. Previous measurements have shown that the results of PowerTOSSIM's energy simulation deviate up to 30% from our measurement results. Our previous measurement setup has been improved and a new prototype was build. Evaluation of our new prototype shows, that energy measurements of mica2 motes are possible with very good accuracy at low costs. The measurement setup can easily be adapted to other platforms. This paper shows an approach how to improve the accuracy of energy simulators for wireless sensor networks. We use our measurement setup to calibrate the energy model of PowerTOSSIM. Finally, our calibrated version of the energy model is evaluated and compared to the original version. Our results show that the accuracy of energy simulators can be greatly improved by our approach.
