The WifiHelper is also used to configure OBSS PD spatial reuse for 802.11ax.
The following line configure a WifiHelper to support OBSS PD spatial reuse
using the ConstantObssPdAlgorithm
with a threshold set to -72 dBm:
WifiHelper wifi;
wifi.SetObssPdAlgorithm ("ns3::ConstantObssPdAlgorithm",
"ObssPdLevel", DoubleValue (-72.0));
There are many other ns-3 attributes that can be set on the above helpers to deviate from the default behavior; the example scripts show how to do some of this reconfiguration.
Questions:
1.Starting which version of ns-3 has this been implemented? I couldn't find it at the release notes. I use ns-3.27 and when i try to use this function it is not recognized.
2. I assume ObssPdLevel is the threshold that is used only for packets that belong to overlapping BSS? If so, how are bss color fields set?
3. Is there any additional information about SetObssPdAlgorithm other then what I posted here?
4.I assume there is only ConstantObssPdAlgorithm and the one that adjusts PD dynamically is not implemented?
ObssPdAlgorithm
(functions and attributes) in doxygen or the list of all attributes page, because I could not find it?
