Hi Toke,

sorry for the long delay.

In ns-3 the 802.11 standard is implemented rather accurately.
The simulator models the standards 802.11a/b/g/n/ac, an initial draft of ax
and the e emendament for the QoS support.
The models support MIMO in 802.11n/ac/ax.
The example 802-11n-mimo in examples/wireless provide and overview of the
MCS and MIMO capabilities by exploring for each HT MCS from 1 to 4 MIMO
streams.

Multiple rate control algorithms are implemented in the simulator. Some of
them are found on real devices, while much others are only available in
literature. There is implemented the minstreal HT algorithm, that could be
useful for benchmark.
The rate control algorithms are modelled by the WiFiRemoteStationManager
class of the wifi module. The class hold a list of per-station-state info
modelled after the struct sta_info in Linux kernel.
Create a new rate control algorithm can be done by introducing a new child
class of the WiFiRemoteStationManager class in the wifi module of the
simulator.

The simulator capabilities seem to fit our needs in term of MCS and MIMO.

Since we are in an exploration phase, how we can contribute to the
exploration?

Thanks,

Pasquale Imputato
