Centralized association management for Radio-On-Demand Networks

The field of mobile data communication has seen very rapid growth with an increased number of mobile terminals connecting to the Internet using the IEEE 802.11 standard for wireless local area network (WLAN). As a result, the amount of energy consumed by WLANs is increasing. To reduce this power consumption, we have proposed a Radio-On-Demand (ROD) WLAN that reduces energy consumption in the operation of WLANs. In this study, we propose a centralized association management scheme for a ROD WLAN. In this scheme, a wireless LAN controller assigns the association between access points and stations, a process that saves power in accordance with network utilization. Using simulation studies, we show that the proposed scheme is effective in saving energy.
