[ns] transmission range in wifi network

[ichrak amdouni]

Hi all,

I need to fix the transmission range for access points and mobile stations
in an infrastructure wifi network.
I mean, how to manage to let communication restricted to a given distance?
I know that in the ns3.3 version, this parameter is not explicitly set, but
affected by others like the TxPower and the channel loss model, but
actually, I experimented multiple matching between those parameters but I
have always stange results (a sta can affiliate with an APdistant of
thousands of meters!!).

Having distinct results from those of the wifi-phy-test.cc example, I wonder
if this issue has a relation with other layers other than the Physical one?
I find the hypothesis very stange but I really reproduced the same scenario
as in wifi-phy-test.cc.
May I missing something?

  - Did someone experiment this issue especially in high mobiliy network? or
have an idea to deal with it differently?
  - Is the transmission range explicitly set in ns 3.4? If  yes, which files
were modified?

Any answer would be very appreciated.

Best regard.
