Config Paths

ns3::WifiRemoteStationManager is accessible through the following paths with Config::Set and Config::Connect:

/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/RemoteStationManager

Attributes

IsLowLatency: If true, we attempt to modelize a so-called low-latency device: a device where decisions about tx parameters can be made on a per-packet basis and feedback about the transmission of each packet is obtained before sending the next. Otherwise, we modelize a high-latency device, that is a device where we cannot update our decision about tx parameters after every packet transmission.

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

The standard has relatively unambiguous rules for selecting a control response rate (the below is quoted from IEEE 802.11-2007, Section 9.6):

To allow the transmitting STA to calculate the contents of the Duration/ID field, a STA responding to a received frame shall transmit its Control Response frame (either CTS or ACK), other than the BlockAck control frame, at the highest rate in the BSSBasicRateSet parameter that is less than or equal to the rate of the immediately previous frame in the frame exchange sequence (as defined in 9.12) and that is of the same modulation class (see 9.6.1) as the received frame...

If no suitable basic rate was found, we search the mandatory rates. The standard (IEEE 802.11-2007, Section 9.6) says:

...If no rate contained in the BSSBasicRateSet parameter meets these conditions, then the control frame sent in response to a received frame shall be transmitted at the highest mandatory rate of the PHY that is less than or equal to the rate of the received frame, and that is of the same modulation class as the received frame. In addition, the Control Response frame shall be sent using the same PHY options as the received frame, unless they conflict with the requirement to use the BSSBasicRateSet parameter.

TODO: Note that we're ignoring the last sentence for now, because there is not yet any manipulation here of PHY options.

If we still haven't found a suitable rate for the response then someone has messed up the simulation config. This probably means that the WifiPhyStandard is not set correctly, or that a rate that is not supported by the PHY has been explicitly requested in a WifiRemoteStationManager (or descendant) configuration.

Either way, it is serious - we can either disobey the standard or fail, and I have chosen to do the latter...

Parameters

address	remote address

packet	the packet to queue
fullPacketSize	the size of the packet after its 802.11 MAC header has been added.

This method is typically invoked just before queuing a packet for transmission. It is a no-op unless the IsLowLatency attribute of the attached ns3::WifiRemoteStationManager is set to false, in which case, the tx parameters of the packet are calculated and stored in the packet as a tag. These tx parameters are later retrieved from GetDadaMode and GetRtsMode.
