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.

void ns3::WifiRemoteStationInfo::NotifyTxSuccess

(

uint32_t

retryCounter

)

Updates average frame error rate when data or RTS was transmitted successfully.

Parameters

retryCounter

is slrc or ssrc value at the moment of success transmission.
