In this report, the problem of interference in dense wireless network deployments is addressed. Two example scenarios are: 1 overlapping basic service sets OBSSes in wireless LAN deployments, and 2 interference among close-by femtocells.The proposed approach is to exploit the interference cancellationand spatial multiplexing capabilities of multiple-input multiple-output MIMO links to mitigate interference and improve theperformance of such networks. Both semi-distributed and fullydistributed protocols for 802.11-based wireless networks standardare presented and evaluated. The philosophy of the approach is tominimize modifications to existing protocols, particularly withinclient-side devices. Thus, modifications are primarily made atthe access points APs. The semi-distributed protocol was fullyimplemented within the 802.11 package of ns-3 to evaluate theapproach. Simulation results with two APs, and with either oneclient per AP or two clients per AP, show that within 5 secondsof network operation, our protocol increases the goodput on thedownlink by about50%, as compared against a standard 802.11nimplementation.
