APPARATUS FOR CONTROLLING POWER OF SENSOR NODES BASED ON ESTIMATION OF POWER ACQUISITION AND METHOD THEREOF

摘要

PURPOSE: Apparatus for controlling power of sensor nodes based on estimation of power acquisition and method thereof are provided to control power of a sensor node with multiple stages according to the power providing condition by analyzing the power consumption of each composition element. CONSTITUTION: A self power acquisition unit(1) obtains self power. The inner sensor(21) senses obtained power from the self power acquisition unit and power consumption. A power blocking unit(3) blocks power of each component of a sensor node. The microprocessor(4) analyzes a power supply and demand situation, estimates obtained power, controls power of each component of a sensor node, and controls communication periods and sensing period of the sensor node.
