Resumo
- Abstract: This paper presents a comparative analysis between two analytical models for the batteries discharge: the Linear model and the Rakhmatov-Vrudhula model. This analysis aims to verify which model is most appropriate for the lifetime estimation of sensor nodes powered by alkaline battery used in Wireless Sensor Networks (WSN). This way, simulations were performed considering the parameters of the alkaline battery and specifications of a sensor node of the family Mica Motes. From the simulation results analysis it was found that the Rakhmatov-Vrudhula model presented a smaller decrease in battery capacity when compared with Linear model, because it can capture the nonlinear effects that occur during the discharge operations.
