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 reduction offered by network coding is significantly different from results reported in the literature based on an energy consumption model that includes the energy emitted while transmitting only. Moreover, it is illustrated that energy can be saved by increasing the transmission power. Whereas this causes individual transmissions to consume more energy, overall energy consumption can be reduced since more coding opportunities arise.
