A Framework for the Estimation and Validation of Energy Consumption in Wireless Sensor Networks

Figure 3

Deviation of theoretically expected output value against the simulated one in the range of hundreds of uA for the estimation of BSN energy consumption before the compensation of the instrumentation amplifier offset voltage. The error reaches 17% in 100 uA range. In -axis the error or deviation as it is calculated in (4) and in -axis the current is drawn by the BSN node as a parametric value.
