Implementation to actually run this TestCase.

Subclasses should override this method to conduct their tests.

Implements ns3::TestCase.

void PowerRateAdaptationTest::TestRrpaa ( )

Test rrpaa function.

This will be the thresholds table. The parameters of the table are:

  • Estimation Window Size (EWND)
  • Maximum Tolerable Loss Probability Threshold (MTL)
  • Opportunistic Rate Increase (and Power Decrease) Probability Threshold (ORI)

We also calculate the needed success and failures to generate a rate or power change: Rate Increase or Power Decrease limits (RI-PD) Rate Decrease or Power Increase limits (RD-PI) Power Decrease limits (PD)

Test that 6 is not enough.

Test that 7 is enough.

Increase rate until maximal rate.

Now we need more successful transmissions to make power decrease. As we are at maximal rate, the power is decreased when it is sure that the failures will not generate a rate decrease.

As rate hasn't change the same amount of success are needed. After 16*45 successful transmissions power is decreased to zero.

After 6 failures the power should be increased.
