Inter-cell interference severely degrades system performance amid growing demand for Internet access via wireless LAN. 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 of 40 and 80MHz. 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 channel and bandwidth patterns calculated by RATOP algorithm on both the managed APs only and unmanaged APs coexistence scenarios. Further, through simulations and indoor experiments, we show that the RATOP works well and improves the throughput compared to conventional schemes. |
