where tproc is the time needed to process the data to exact and Pproc the power consumption of the MCU processing the data. Using equation 6, the daily energy consumption in case of onboard processing is only 27.7J per day instead of 60.5J resulted by equation 5. This results to be 53% less energy than the version transmitting raw data, which demonstrates the energy efficiency of the onboard data processing of our proposed solution.
