ArfRateControl¶

Package: inet.linklayer.ieee80211.mac.ratecontrol

simple module ArfRateControl

Implements the Auto Rate Fallback (ARF) adaptive rate control mechanism.

Inheritance diagram¶

Extends¶

Name	Type	Description
AarfRateControl	simple module	Implements the Adaptive ARF (AARF) rate control mechanism, which was initially described in IEEE 802.11 Rate Adaptation: A Practical Approach, by M. Lacage, M.H. Manshaei, and T. Turletti, 2004.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“{currentMode}”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
initialRate	double	-1bps	-1 means the fastest mandatory rate
interval	double	50ms	The rate (unconditionally) increases after each time interval.
increaseThreshold	int	10	Number of successful transmissions needed to increase the rate
decreaseThreshold	int	2	Number of consecutive unsuccessful transmissions (in the sense that the ACK does not arrive within the timeout)
increaseThresholdFactor	double	1	When the transmission of the probing packet fails, increaseThreshold is multiplied by increaseThresholdFactor.
maxIncreaseThreshold	int	50	Upper bound for increaseThreshold.
