Abstract

The recent electric power shortage has led to the vigorous study for energy conservation in the many different fields. In this paper, cell zooming technology, which can reduce the energy loss at the base stations controlling the transmission power of the stations depending on the changing trffic density for reduce energy consumption that occurs when there is little or no trffic in the service area, is proposed and energy conservation is confirmed by comparing base stations' service scenario depending on traffic change.

최근 전력난으로 인해 각 분야에서 에너지 절감을 위한 기술에 대한 연구가 활발하게 진행됨에 따라 네트워크분야에서도 에너지 절감을 위한 연구가 활발히 진행되고 있다. 본 논문에서는 변화하는 트래픽 밀도에 따라 기지국의 전송파워를 조절하여 트래픽이 없거나 적은 경우 발생하는 불필요한 기지국의 에너지 소모를 줄임으로서 기지국의 소모 에너지를 절감하는 셀 주밍 기법을 제안하고, 트래픽의 변화에 따른 기지국의 서비스 시나리오를 비교하여 에너지 절감을 확인하였다.
