A functional approach for wireless sensor node energy consumption modeling

Embedded applications in the field of wireless sensor nodes are becoming more and more sensitive to energy consumption. This latter actually depends on the autonomy of the application, but also on its performance. One must take into account the constraints of energy consumption when specifying and designing an application. In this document, instead of considering applications, we raise the level of abstraction to study various functions. We present a classification of possible functions in wireless sensor nodes. Then, we propose a functional approach modeling in order to get a more accurate estimate in term of energy consumption for each function. Input and output parameters of the functions are investigated to identify the relationships between them. The final goal of this work is to provide an efficient energy consumption optimization tool for wireless sensor nodes designers.
