Member Function Documentation

CalculateAveragingCoefficient()

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.

Returns

average coefficient for frame error rate
