Abstract

Restricted Access Window (RAW) has been designed to improve power saving efficiency by reducing collisions of contending stations in the IEEE 802.11ah Wireless Local Area Networks (WLANs). We conduct simulations in order to observe the stations' operations influencing the lengths of the Restricted Access Window (RAW). From the observation, we consider how to adjust the stations' operations for proper RAW managements.

IEEE 802.11ah 무선랜 환경에서 Restricted Access Window는 단말간 충돌을 완화시켜 수면 동작의 효율성을 높이기 위하여 도입되었다. 모의실험을 통해 Restricted Access Window (RAW)의 길이에 영향을 주는 무선랜 단말의 동작 방식을 관찰하고 적정한 RAW의 값을 설정하기 위해 무선랜 단말의 동작을 어떻게 제어하는 것이 필요한지 알아본다.
