// This is an example to verify performance of 802.11aa groupcast with retries (GCR) in comparison
// with the usual NoAck/NoRetry retransmission policy. In the latter, a groupcast frame is
// transmitted only once, whereas GCR allows to retransmit groupcast frames to improve reliability.
//
// The simulation considers a single 802.11ax AP and a configurable number of GCR-capable STAs in an
// infrastructure network. Multicast traffic is generated from the AP to all the non-AP STAs and
// artificial errors can be introduced to mimic interference on the wireless channel.
//
// There are a number of command-line options available to control the scenario under test. The list
// of available command-line options can be listed with the following command:
// ./ns3 run "wifi-multicast --help"
//
// The main command-line options are:
// --gcrRetransmissionPolicy: control the retransmission policy by selecting "NoAckNoRetry" for
// no retransmission, "GcrUr" for GCR with unsolicited retries or "GcrBlockAck" for GCR Block Ack
// --nStations: control the number of GCR-capable STAs associated to the AP
// --accessCategory: control the access category to use for the multicast traffic
// --multicastFrameErrorRate: set the artificial frame error rate for the groupcast traffic
// --nRetriesGcrUr: if GCR-UR is selected, this parameter controls the maximum number of retries
// --gcrProtection: select the protection mechanism for groupcast frames if GCR-UR or GCR-BA is
// used, either "Rts-Cts" or "Cts-To-Self" can be selected
//
// Example usage for NoAckNoRetry and a frame error rate of 20%:
// ./ns3 run "wifi-multicast --gcrRetransmissionPolicy=NoAckNoRetry --multicastFrameErrorRate=0.2"
// which outputs:
