Demo Abstract: Software-Based Sensor Node Energy Estimation

Being able to estimate the energy consumption of sensor nodes is essential both for evaluating existing sensor network mechanisms and for constructing new energy-aware mechanisms. The authors present a software-based mechanism for estimating the energy consumption of sensor node at run-time. Unlike previous energy estimation mechanisms, the authors' mechanism does not require any additional hardware components or add-ons. Their demonstration shows the energy estimation in practice on a small network of Tmote Sky motes running the Contiki operating system.
