Abstract (EN): An important feature for the design of algorithms for Wireless Sensor Networks is the estimation of its lifetime. To design communication protocols and data collection algorithms with low power consumption, a key factor is the ability to measure the actual consumption in the sensor node. This ability enables the verification of theoretical/simulated models, allowing an accurate estimation of the network longevity. This paper proposes a system for measuring the energy consumption levels of sensor nodes in normal operation, allowing the estimation of the real lifetime for each node, enabling the optimization of energy aware protocols. Presented data is related to the energy consumption of a MicaZ node and to the behavior of the full discharge of a battery pack. A set of polynomial functions describing this energy discharge are also presented that can be easily inserted into the battery models of network simulators to obtain a more realistic behavior.
