Abstract(in English) | The increased density of wireless LAN access points (APs) based on the IEEE 802.11 standard has induced inter-cell interference that severely degrades system performance. This problem is getting worse with the increase of IEEE 802.11n- and 802.11ac-based APs, which establish basic service sets with wider channel bandwidths than legacy 802.11a APs. In order to mitigate this problem, we have proposed an efficient radio resource allocation scheme called RATOP that can be applied to a managed wireless LAN system with a central coordinator. On the basis of channel monitoring results, capability, and data traffic information obtained from APs, the central coordinator computes the quasi-optimal frequency channel and channel bandwidth of each AP in such a way that the given utility function is maximized. In this paper we evaluate the RATOP algorithm on the coexistence scenarios of 802.11a/n/ac, and show that the RATOP works well and improves the throughput compared to legacy scheme. |
