ArfRateControl

simple module

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

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the 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
initialRate	double	-1bps	-1 means 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 ACK does not arrive within timeout) needed to increase the rate
increaseThresholdFactor	double	1	When the transmission of probing packet fails, we multiply by "increaseThresholdFactor" the increaseThreshold.
maxIncreaseThreshold	int	50	Upper bound for increaseThreshold.
