The energy consumption of a wireless device is modeled by including not only
the energy emitted while transmitting, but also energy consumed by supporting
circuitry. In particular also receiver energy consumption is taken into account. It
is shown that under this model, compared to traditional routing, the energy re-
duction offered by network coding is significantly different from results reported
in the literature based on an energy consumption model that includes the en-
ergy emitted while transmitting only. Moreover, it is illustrated that energy can
be saved by increasing the transmission power. Whereas this causes individ-
ual transmissions to consume more energy, overall energy consumption can be
reduced since more coding opportunities arise.
