Recent investigations show that Access Points (APs) of Wireless Local Area Networks (WLANs) are idle during much of the time, and, (ii) an AP in its idle state without forwarding any packets still consumes a large percentage of power. Therefore, it is necessary to put idle APs into sleep so as to realize green WLANs. The problem, however, is how to quickly and reliably activate APs from sleep when nodes initiate new data flows. Aiming at realizing Radio-On-Demand WLANs, in this paper, the authors suggest exploiting burst transmission of WLAN frames to convey wake-up IDs from nodes to APs.
