Recently, wireless networking devices that depend on the limited Battery and power-saving of wireless hosts became important issue. Batteries can provide a finite amount of energy, therefore, to increase battery lifetime, it is important to design techniques to reduce energy consumption by wireless hosts. This paper improved power saying mechanism in Distributed Coordination Function(DCF) of IEEE 802.11. In the IEEE 802.11 power saving mechanism specified for DCF, time is divided into so-called beacon intervals. At the start of each beacon interval, each node in the power saving mode periodically wakes up during duration called the ATIM Window. The nodes are required to be synchronized to ensure that all nodes wake up at the same time. During the ATIM window, the nodes exchange control packets to determine whether they need to stay awake for the rest of the beacon interval. The size of the ATIM window has considerably affected power-saving. This paper can provide more power-saving than IEEE 802.11 power saving mode because ATIM window size is efficiently increased or decreased.

미국의 도널드 트럼프 대통령은 최근 한 연설에서 미국의 국가 에너지 독립을 확고히 하고, 나아가 미국의 세계 에너지 제패 시대를 열어나가기 위한 6대 에너지 프로젝트를 구상 중에 있으며, 그 중 첫 번째로 국가 원자력 정책을 전면 재검토하는 작업에 착수한다고 발표했다.
