Abstract

This paper examines the accuracy of software-based on-line energy estimation techniques. It evaluates today’s most widespread en- ergy estimation model in order to investigate whether the current me- thodology of pure software-based energy estimation running on a sensor node itself can indeed reliably and accurately determine its energy con- sumption - independent of the particular node instance, the traffic load the node is exposed to, or the MAC protocol the node is running. The pa- per enhances today’s widely used energy estimation model by integrating radio transceiver switches into the model, and proposes a methodology to find the optimal estimation model parameters. It proves by statistical validation with experimental data that the proposed model enhance- ment and parameter calibration methodology significantly increases the estimation accuracy.
