Abstract

IEEE 802.16e standard defines different Sleep Mode Operations according to kind of services which aims at saving energy for MS efficiently. The previous study of Sleep Mode Operation is limited for single service environment, real sleep interval is decreased because different Sleep Mode Operations are applied at once when MS is on multi service. The proposed Enhanced Sleep Mode Operation increasing real sleep interval of this paper guarantees QoS(Quality of Services) which is same as standard, minimizes energy consumption when different Sleep Mode Operations are applied at once. Therefore Enhanced Sleep Mode Operation of this paper will be useful in case of increase battery life time as well as guaranteeing QoS for MS in IEEE 802.16 system.

IEEE 802.16e 표준에서는 이동 단말의 제한된 에너지를 효율적으로 관리하기 위하여 서비스의 종류에 따라 서로 다른 수면모드 작동기법을 정의하고 있다. 기존의 수면모드 작동기법에 대한 연구는 이동 단말이 하나의 서비스를 받는 환경으로 제한되어 있으므로, 여러 서비스를 동시에 받을 경우 서로 다른 수면모드 작동기법을 동시에 적용하여 실제로 에너지를 절약하는 구간을 크게 감소시킨다. 본 논문에서 제안하는 에너지 절약 기법은 이동 단말이 여러 서비스를 동시에 받는 환경에서 실제로 에너지를 절약하는 구간을 증가시킴으로써, 에너지 소모를 최소화하고 기존과 비슷한 수준의 QoS(Quality of Services)를 보장한다. 향후 IEEE 802.16e 시스템에서 이동 단말의 제한된 배터리 수명을 증가시키면서 QoS를 보장하고 싶을 경우, 본 논문에서 제안한 에너지 절약 기법이 유용하게 사용될 수 있을 것이다.
