Method and system for interference detection and mitigation

摘要

In a method for adjusting the modulation of information onto subcarriers transmitted on a network, a first modulation profile of a network node on the network is set a first density. A plurality of messages in support of a link maintenance operation (LMO) on the network are monitored. The first modulation profile of the network node is updated to a second modulation profile having a second density. The updating is based on the monitored messages. Interference is detected by determining that a link between the first network node and a second network node on the network is not conveying a predetermined class of messages correctly. The first network node is set to a third modulation profile more robust than the first and second modulation profiles in response to the detected interference. The third modulation profile is common to each network node on the network.

1. A method for adjusting modulation on a network, the method comprising;
a) determining that at least one of a probe request or probe report has been transmitted during a link maintenance operation (LMO) between an LMO node and a network node; b) detecting interference on a link to the LMO node from a network coordinator (NC) on the network that interferes with the reception of the transmitted probe request or probe report; and c) in response to the detected interference, the NC forcing the use of a robust modulation profile to retransmit the at least one of a probe request or probe report, wherein foreing the use of a robust modulation profile includes sending a diversity mode modulation override from the NC to the LMO node in a beacon packet.
