Recently, as the use of wireless Internet increases, access point (AP) installation has increased rapidly, only to increase the total power consumed by AP in wireless local area network (WLAN). Because an AP always wakes up regardless of the real use, the unnecessary power by the AP may be consumed. If we consider environments such as office or home, where an AP is used during certain hours of a day, an enormous amount of power waste may occur. This increase of power waste is contrary to the trend to reduce the cost of power production, and has a negative influence on natural environments. Therefore, it is necessary to improve the power efficiency; i.e., the power consumed by the AP need to be reduced. In this paper, we propose a power saving algorithm according to the existence of associated stations (STAs) and consecutive traffics in WLAN. The proposed algorithm applies a new sleep state to WLAN AP. According to the analysis result, the proposed algorithm consumes less power approximately 29% than the conventional (not using power saving algorithm).
