Member Function Documentation

double ns3::WifiRemoteStationInfo::CalculateAveragingCoefficient ( )

private

Calculate averaging coefficient for frame error rate. Depends on time of the last update.

Attention

Calling this method twice gives different results, because it resets time of last update.
