Detailed Description

Make sure that Wifi STA is correctly associating to the best AP (i.e., nearest from STA).

We consider 3 AP and 1 STA. This test case consisted of three sub tests:

  • The best AP sends its beacon later than the other APs. STA is expected to associate to the best AP.
  • The STA is using active scanning instead of passive, the rest of the APs works normally. STA is expected to associate to the best AP
  • The nearest AP is turned off after sending beacon and while STA is still scanning. STA is expected to associate to the second best AP.

See Bug 2399

Todo:
Add explicit association refusal test if ns-3 implemented it.
