“…In the proposed scheme, maximum aggregation utilization is defined, and STAs are not aggregated with a specific AP beyond this value. In the proposed scheme, MELU [5] is used as the algorithm for selecting the new AP. In MELU, STAs are aggregated with APs so that the expected utilization, U expect , after the aggregation of the STA is minimized.…”

“…In [5], [6], [7], we proposed an STA aggregation scheme in which the reassociated APs are decided based on the AP utilization and demonstrated that the proposed scheme improves the energy efficiency in ROD. However, since WLANs are widely deployed as network infrastructure, APs in a WLAN are likely affected by and interfere with nearby WLANs.…”

With the rapid growth of the Internet, deploying energy-efficient networking technology is an urgent matter. In particular, wireless LAN (WLAN), which is widely used due to its ease of deployment and low cost of installation, is also required to be energy efficient. For this purpose, R & D activities for RadioOn-Demand-Networks (ROD) have been proposed. In ROD networks, access points (APs) have been equipped with wakeup receivers, switching their status to sleep mode, depending on the traffic distribution in the network. In the present paper, a station (STA) aggregation scheme in ROD networks considering channel interference is proposed. In this scheme, APs cooperate with each other and aggregate their STAs depending on the channel utilization information rather than the AP utilization. The simulation results reveal the scheme effectiveness in terms of power savings without throughput degradation in WLANs even in the presence of interference.
