Which Language is Used in ns3

                 In general, the programming language that is mainly deployed for the implementation of Ns3 is C++. For your reference, we have highlighted some process based on Ns3 simulation through the utilization of C++ code and the process such as.

  • Creation of nodes
NodeContainer IoTNodes;
NodeContainer UserNodes;
NodeContainer GatewayNode;
IoTNodes.Create (numNodes);
UserNodes.Create (numusers);
GatewayNode.Create (1);
• Wifi configuration WifiHelper wifi;
Ptr extension;
Ptr extenAH;
YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default ();
wifiPhy.Set ("RxGain", DoubleValue (-30));
wifiPhy.SetPcapDataLinkType (YansWifiPhyHelper::DLT_IEEE802_11_RADIO);
YansWifiChannelHelper wifiChannel;
wifiChannel.SetPropagationDelay ("ns3::ConstantSpeedPropagationDelayModel");
wifiChannel.AddPropagationLoss ("ns3::FriisPropagationLossModel");
wifiPhy.SetChannel (wifiChannel.Create ());
NqosWifiMacHelper wifiMac = NqosWifiMacHelper::Default ();
wifi.SetStandard (WIFI_PHY_STANDARD_80211b);
wifi.SetRemoteStationManager ("ns3::ConstantRateWifiManager","DataMode",StringValue (phyMode),"ControlMode",StringValue (phyMode));
wifiMac.SetType ("ns3::AdhocWifiMac");
NetDeviceContainer devices = wifi.Install (wifiPhy, wifiMac, IoTNodes);
  • Mobility configuration
mobility1.SetMobilityModel ("ns3::ConstantPositionMobilityModel");
AnimationInterface::SetConstantPosition (GatewayNode.Get (0), 450, 250);

            Subsequently, let’s have a look over the process that how we have to implement C++ code in Ns-3.26. For that we have to implement the C++ based simulation main file through the below mentioned command.

sudo ./waf –run Main –vis
Implementation of C++ Simulation Main File

          The below mentioned screen is about the simulation result that is acquired through the implementation of C++ code in Ns-3.26.
