ERROR AND DISTORTION CONTROL METHOD FOR A DISCHARGE HOUR METER IN A WIRELESS SENSOR NETWORK CAPABLE OF INCREASING ENERGY EFFICIENCY BY REDUCING POWER CONSUMPTION

摘要

PURPOSE: An error and distortion control method for a discharge hour meter in a wireless sensor network is provided to minimize sensor node activation period according to time by distinguishing all events in a sensor network.;CONSTITUTION: Message transmission and reception time is measured between a parent sensor node(101) and a child sensor node(103). A first discharge hour meter is synchronized based on the measured transmission and reception time. The first discharge hour meter is corrected based on the result of distribution calculation for the transmission and reception time. A message including information related to a sensor node is constructed. The constructed message is transmitted and received by a sensor network. The sensor network includes the parent sensor node and the childe sensor node.;COPYRIGHT KIPO 2012
