Centralized channel allocation scheme in densely deployed 802.11 wireless LANs

In densely deployed WLAN environment, the WLAN can experience severe inter-cell interference which may cause a considerable performance degradation. In order to mitigate this issue, we propose a centralized channel allocation scheme considering the uncontrolled neighboring access points. The proposed scheme estimates the channel utilization based on the received beacon signals without any help from clients. The performance of the proposed scheme is evaluated by the experiment. Despite the simplicity of the proposed scheme, it shows the best performance within compared schemes.
