“…At the same time it is necessary for "smart dust" sensor nodes to have as long autonomous lifetime as it is possible. To increase sensor node autonomous lifetime, developers strive to select electronic components with low power consumption, to use energy harvesting technologies [1], [2], to equip sensor nodes with power sources with huge capacity [1], [3] or to use "smart" algorithms and methods [4], [3], [13] to decrease power consumption.…”
