Query: Online Estimation of Battery Lifetime for Wireless Sensors Network   Battery is a major hardware component of wireless sensor networks. Most of
them have no power supply and are generally deployed for a long time.
Researches have been done on battery physical model and their adaptation for
sensors. We present an implementation on a real sensor operating system and how
architectural constraints have been assumed. Experiments have been made in
order to test the impact of some parameter, as the application throughput, on
the battery lifetime.
