- Abstract
- An apparatus for controlling power of sensor nodes based on estimation of power acquisition, includes: a self power acquisition unit acquiring self power; an internal sensing unit sensing power acquired from the self power acquisition unit and consumed power; a power cut-off unit cutting-off power for each component of the sensor nodes; and a microprocessor receiving information of acquired power and consumed power from the internal sensing unit to analyze a supply and demand of power, estimating the acquired power using annual meteorological statistics data and recent weather forecast data, controlling power for each component of the sensor nodes through the power cut-off unit according to the estimation of the acquired power, and controlling a sensing period and a communication period of the sensor nodes.
