  Abstract

Power Saving Mode(PSM) based on IEEE 802.11 defines Awake state in which data can be transmitted and received and Sleep state in which power of the Wi-Fi interface is cut off to reduce the power consumption of the wireless devices. But it has not been addressed for Access Point(AP), so the AP can not enter the Sleep state and always maintains the Awake state. Moreover, the AP consumes a great deal of power because it handles traffic forwarding between external network and the clients, beacon transmission, connection with clients, etc. This applies equally to MAP(Mobile Access Point), which directly affects the battery life in tethering-like environments. In this paper, we propose an algorithm that sleeps at a time when AP determines that data will not be generated due to adaptation to current wireless network traffic in order to reduce power consumption of mobile AP. We simulated the existing method and the proposed method using the network simulator ns-3, and analysis is performed on the results.
