Abstract

A method of detecting a hidden node is disclosed. Reports from a plurality of access points (APs) are received. The method includes determining that transmissions from a second AP are not detected by a first AP based on the received report from the first AP. The method includes determining that transmissions from a client associated with the first AP are detected by the second AP based on the received report from the second AP. The method further includes detecting that the second AP is a hidden node, wherein transmissions from the hidden node interfere with transmissions between the client and the first AP, and wherein the detection is based at least in part on the determination that transmissions from the second AP are not detected by the first AP and the determination that transmissions from the client associated with the first AP are detected by the second AP.
