// This is a simple example of an IEEE 802.11n Wi-Fi network.
|
|
//
|
|
// The main use case is to enable and test SpectrumWifiPhy vs YansWifiPhy
|
|
// under saturation conditions (for max throughput).
|
|
//
|
|
// Network topology:
|
|
//
|
|
// Wi-Fi 192.168.1.0
|
|
//
|
|
// STA AP
|
|
// * <-- distance --> *
|
|
// | |
|
|
// n1 n2
|
|
//
|
|
// Users may vary the following command-line arguments in addition to the
|
|
// attributes, global values, and default values typically available:
|
|
//
|
|
// --simulationTime: Simulation time in seconds [10]
|
|
// --distance: meters separation between nodes [50]
|
|
// --index: restrict index to single value between 0 and 31 [256]
|
|
// --wifiType: select ns3::SpectrumWifiPhy or ns3::YansWifiPhy [ns3::SpectrumWifiPhy]
|
|
// --errorModelType: select ns3::NistErrorRateModel or ns3::YansErrorRateModel [ns3::NistErrorRateModel]
|
|
// --enablePcap: enable pcap output [false]
|
|
//
|
|
// By default, the program will step through 64 index values, corresponding
|
|
// to the following MCS, channel width, and guard interval combinations:
|
|
// index 0-7: MCS 0-7, long guard interval, 20 MHz channel
|
|
// index 8-15: MCS 0-7, short guard interval, 20 MHz channel
|
|
// index 16-23: MCS 0-7, long guard interval, 40 MHz channel
|
|
// index 24-31: MCS 0-7, short guard interval, 40 MHz channel
|
|
// index 32-39: MCS 8-15, long guard interval, 20 MHz channel
|
|
// index 40-47: MCS 8-15, short guard interval, 20 MHz channel
|
|
// index 48-55: MCS 8-15, long guard interval, 40 MHz channel
|
|
// index 56-63: MCS 8-15, short guard interval, 40 MHz channel
|
|
// and send packets at a high rate using each MCS, using the SpectrumWifiPhy
|
|
// and the NistErrorRateModel, at a distance of 1 meter. The program outputs
|
|
// results such as:
|
|
//
|
|
// wifiType: ns3::SpectrumWifiPhy distance: 1m
|
|
// index MCS width Rate (Mb/s) Tput (Mb/s) Received
|
|
// 0 0 20 6.5 5.96219 5063
|
|
// 1 1 20 13 11.9491 10147

|
// 2 2 20 19.5 17.9184 15216
|
|
// 3 3 20 26 23.9253 20317
|
