“…The limited energy of the battery is an important factor in determining the lifespan of a sensor network. A number of papers [1][2][3][4][5] in the area of WSNs have proposed a system configuration and routing scheme in consideration of the residual energy in a sensor system. For example, information about residual energy can be employed in system-level maximization, such as the duty cycle control or transmission-range control, as well as in network-level maximization, such as energy-aware routing schemes.…”

A number of studies have been actively conducted to address limited energy resources in sensor systems over wireless sensor networks. Most of these studies are based on energy-aware schemes, which take advantage of the residual energy from the sensor system's own or neighboring nodes. However, existing sensor systems estimate residual energy based solely on voltage and current consumption, leading to inaccurate estimations because the residual energy in real batteries is affected by temperature and load. This misinformation makes a complete nonsense of existing energy-aware research, which is not allowed in reliable WSN applications. In this study, therefore, an efficient residual-energy estimation scheme is proposed in consideration of not only the voltage but also the temperature and load characteristics of batteries. The performance of the proposed scheme was verified through an experiment and simulations in the actual environment, and its effect gets more notable when the scale of the WSN goes larger.

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
