Table-based Effective Estimation of Residual Energy for Battery-based Wireless Sensor System

Abstract

Up to date, numerous studies on wireless sensor networks have been performed to overcome the Energy-Constraint of the sensor system. Existing schemes for estimating the residual energy have considered only voltage of sensor system. However battery performance in the real is affected by temperature and load. In this paper we introduce more accurate scheme, for the use in wireless sensor node, based on the interpolation of lookup tables which allow for temperature and load characteristics, as well as battery voltage.▸Keywords : Wireless Snesor Network, Battery-based sensor system, Alkaline battery, Estimation scheme of residual energy•제1저자 : 김재웅 •교신저자 : 노동건
