Wireless LANs (WLANs) are widely used as network infrastructure due to their ease of deployment and low installation costs. Access points (APs) in WLANs are operated continuously in order to provide connectivity for stations (STAs); however, this wastes a non-negligible amount of energy. To reduce the power consumption of APs in such a WLAN environment, radio-on-demand (ROD) networks were developed. Within the ROD framework, we previously proposed a STA aggregation scheme in which APs cooperate with each other and aggregate their STAs, and demonstrated that the proposed scheme could provide power savings in an environment with a light traffic volume. In present paper, we propose a STA reassociation scheme, as an enhancement of our STA aggregation scheme, that achieves high power saving while autonomously avoiding degradation of communication quality under any network load
