APPARATUS FOR COOPERATIVE SENSING BASED ON ALLOWABLE ERROR RANGE OF A SENSOR IN THE RADIO SENSOR NODE CAPABLE OF EXTENDING THE LIFETIME OF THE SENSOR NODE

摘要

PURPOSE: A method and an apparatus for cooperative sensing based on allowable error range of a sensor in the radio sensor node are provided to reduce energy for the electrical transmission of sensor data to a user level by lowering recognition about the allowable error range to the sensing level of the sensor node at user level.;CONSTITUTION: A sensor module(918) outputs sensor data by at least one or more sensor. An AER(Allowed Error Range) sensing block(910) calculates the AER according to at least one sensor through the measured sensor data and sensor profile information corresponding to at least one sensor. Based on the AER, the AER sensing block decides the sensor data for transmitting to upper node among the sensor data.;COPYRIGHT KIPO 2010
