以下是一个基于NS-3版本3.27的WIFI性能仿真代码的示例:
```c++
#include "ns3/core-module.h"
#include "ns3/wifi-module.h"
#include "ns3/mobility-module.h"
#include "ns3/internet-module.h"
#include "ns3/applications-module.h"
#include "ns3/netanim-module.h"
#include "ns3/flow-monitor-module.h"
using namespace ns3;
NS_LOG_COMPONENT_DEFINE("WifiPerformance");
int main(int argc, char *argv[])
{
// Enable logging
LogComponentEnable("WifiPerformance", LOG_LEVEL_INFO);
// Create nodes
NodeContainer nodes;
nodes.Create(2);
// Create wifi devices and install them on nodes
WifiHelper wifi;
wifi.SetStandard(WIFI_PHY_STANDARD_80211n_5GHZ);
wifi.SetRemoteStationManager("ns3::ConstantRateWifiManager",
"DataMode", StringValue("HtMcs7"),
"ControlMode", StringValue("HtMcs7"));
WifiMacHelper mac;
Ssid ssid = Ssid("ns3-wifi");
mac.SetType("ns3::StaWifiMac",
"Ssid", SsidValue(ssid),
"ActiveProbing", BooleanValue(false));
NetDeviceContainer devices = wifi.Install(mac, nodes);
// Setup mobility
MobilityHelper mobility;
mobility.SetPositionAllocator("ns3::GridPositionAllocator",
"MinX", DoubleValue(0.0),
"MinY", DoubleValue(0.0),
"DeltaX", DoubleValue(5.0),
"DeltaY", DoubleValue(10.0),
"GridWidth", UintegerValue(3),
"LayoutType", StringValue("RowFirst"));
mobility.SetMobilityModel("ns3::RandomWalk2dMobilityModel",
"Bounds", RectangleValue(Rectangle(-50, 50, -50, 50)));
mobility.Install(nodes);
// Install internet stack
InternetStackHelper stack;
stack.Install(nodes);
// Assign IP addresses
Ipv4AddressHelper address;
address.SetBase("10.1.1.0", "255.255.255.0");
Ipv4InterfaceContainer interfaces = address.Assign(devices);
// Install TCP receiver on server node
uint16_t port = 8080;
PacketSinkHelper packetSinkHelper("ns3::TcpSocketFactory",
InetSocketAddress(interfaces.GetAddress(1), port));
ApplicationContainer sinkApps = packetSinkHelper.Install(nodes.Get(1));
sinkApps.Start(Seconds(0.0));
sinkApps.Stop(Seconds(20.0));
// Install TCP sender on client node
OnOffHelper onoffHelper("ns3::TcpSocketFactory",
InetSocketAddress(interfaces.GetAddress(1), port));
onoffHelper.SetAttribute("DataRate", StringValue("100Mbps"));
onoffHelper.SetAttribute("PacketSize", UintegerValue(1500));
ApplicationContainer clientApps = onoffHelper.Install(nodes.Get(0));
clientApps.Start(Seconds(1.0));
clientApps.Stop(Seconds(20.0));
// Setup flow monitor
FlowMonitorHelper flowmon;
Ptr<FlowMonitor> monitor = flowmon.InstallAll();
// Run simulation
Simulator::Stop(Seconds(20.0));
Simulator::Run();
Simulator::Destroy();
// Output results
monitor->CheckForLostPackets();
Ptr<Ipv4FlowClassifier> classifier = DynamicCast<Ipv4FlowClassifier>(flowmon.GetClassifier());
std::map<FlowId, FlowMonitor::FlowStats> stats = monitor->GetFlowStats();
for (auto iter = stats.begin(); iter != stats.end(); ++iter)
{
Ipv4FlowClassifier::FiveTuple tuple = classifier->FindFlow(iter->first);
NS_LOG_INFO("Flow " << iter->first << " (" << tuple.sourceAddress << " -> " << tuple.destinationAddress << "):");
NS_LOG_INFO(" Tx Packets: " << iter->second.txPackets);
NS_LOG_INFO(" Tx Bytes: " << iter->second.txBytes);
NS_LOG_INFO(" Tx Bitrate: " << iter->second.txBytes * 8.0 / iter->second.timeLastTxPacket.GetSeconds() / 1000000 << " Mbps");
NS_LOG_INFO(" Rx Packets: " << iter->second.rxPackets);
NS_LOG_INFO(" Rx Bytes: " << iter->second.rxBytes);
NS_LOG_INFO(" Rx Bitrate: " << iter->second.rxBytes * 8.0 / iter->second.timeLastRxPacket.GetSeconds() / 1000000 << " Mbps");
}
// Output PCAP trace file
flowmon.SerializeToXmlFile("wifi-performance.flowmon", true, true);
return 0;
}
```
要运行此代码,可以按照以下步骤操作:
1.将代码保存到名为“wifi-performance.cc”的文件中。
2.在终端中导航到保存代码的文件夹。
3.编译代码:
```bash
$] ./waf configure
$] ./waf
```
4.运行仿真:
```bash
$] ./waf --run wifi-performance
```
5.当仿真完成时,程序将输出一些有关仿真结果的信息,并生成一个名为“wifi-performance.flowmon”的PCAP跟踪文件。
