Energy saving is one of the most important issues of wireless sensor networks that are gaining a lot of attention. In other words, energy modeling plays a greater role in energy optimization that helps designers to produce an economical and practical design of sensor nodes. In this paper, an energy consumption model is proposed considering most of the parameters of both MAC and physical layers, unlike other related works that concern with either MAC or physical layer parameters. The proposed energy consumption model is validated with real measurements and NS-2 simulator. Results show good agreement between proposed model, experimental measurements and NS-2 simulator with mean absolute percentage error less than 6%. The validated model is used to optimize transmitted power to achieve minimum energy consumption. Finally, a closed-form expression for optimum transmitted power is derived for different modulation schemes.
