Abstract

A mobile station(MS) in an 802.16e network manages its limited energy using the sleep mode operation. An MS can power down its physical operation components during the unavailability interval of the sleep mode. To reduce energy consumption by increasing the unavailability interval, this paper proposes an enhanced power saving mechanism(ePSM) when both activated Type I and Type II power saving classes(PSCs) exist in an MS. A performance evaluation confirms that ePSM results in the improved performance in terms of the unavailability interval as well as the energy consumption than conventional schemes.

IEEE 802.16e는 수면 모드 작동기법을 사용하여 이동 단말기(Mobile Station: MS)의 제한된 에너지를 관리한다. MS는 수면 모드의 비가용 구간에 물리적인 작동 요소의 출력을 낮출 수 있다. 이 논문은 비가용 구간를 체계적으로 증가시켜 에너지 소모율을 감소시키기 위하여, MS에 I형과 II형의 활성화된 절전 클래스(PSC)가 존재할 때 강화된 절전 메커니즘(ePSM)을 제안한다. 성능 평가 결과, ePSM은 비가용 구간뿐 아니라 에너지 소비에 있어서도 기존 방식에 비해 성능을 향상시킨 것을 확인하였다.
