\cite{orgerie_ecofen:_2011} is used to model the energy consumption of the network part. ECOFEN
is a ns-3 network energy module for ns-3 dedicated to wired network energy estimation. It is
based on an energy-per-bit model including static consumption by assuming a linear relation
between the amount of data sent to the network interface and the power consumption. The different
