초록

다양한 서비스의 활성화로 인한 이동 단말의 사용 시간 및 트래픽의 증가로 인해 배터리로 구동되는 이동 단말의 전력 절감 기술이 주목받고 있다. 본 논문은 4G 기술 중의 하나인 Mobile WiMAX라 불리는 IEEE 802.16m의 전력 절감 기술에 대해서 기술한다. 먼저 IEEE 802.16m의 기초가 되는 IEEE 802.16e 전력 절감 방안과의 차이점 및 기술적 특정을 살펴본다. 이동 단말의 효율적인 전력 관리를 위해 패킷들의 도착 분포 정보를 기반으로 동적 수면 사이클 조절 방안을 제안한다. 제안한 방안을 에너지 절감 측면과 패킷 대기 지연 시간 측면에서 살펴본다.

As the usage of mobile stations increases thanks to various services, power saving mechanisms of mobile station operated by battery power have been gained much attention. This paper presents a power saving mechanism(PSM) of IEEE 802.16m, called Mobile WiMAX, for 4G mobile technology. This paper first presents different points of the PSM of IEEE 802.16m from IEEE 802.16e, which is a basis of IEEE 802.16m. This paper proposes a dynamic sleep cycle adjustment algorithm for improving the performance of IEEE 802.16m PSM by considering the arrival pattern of incoming packets from base station. Performance of the algorithm is analyzed in terms of energy consumption as well as waiting time of packets.
