tcp application on 2 AP

[Amira Hadzialic]

Hello everyone, 

I am trying to simulate tcp traffic from two APs to two different nodes.

I am using wifi-spatial-reuse.cc , but with changes to tcp application from udp. It builds successfully but the throughput is 0 on both BSS.

I someone could give me some hints what I am doing wrong I would be very grateful.

Part of the code where application is installed:

//BSS 1

  

 uint16_t port = 50000;

      Address apLocalAddressA (InetSocketAddress (Ipv4Address::GetAny (), port));

      PacketSinkHelper packetSinkHelperA ("ns3::TcpSocketFactory", apLocalAddressA);

ApplicationContainer sinkAppA = packetSinkHelperA.Install (wifiApNodes.Get (0));

      sinkAppA.Start (Seconds (0.0));

      sinkAppA.Stop (Seconds (duration + 1));

 OnOffHelper onoffA ("ns3::TcpSocketFactory",Ipv4Address::GetAny ());

      onoffA.SetAttribute ("OnTime",  StringValue ("ns3::ConstantRandomVariable[Constant=1]"));

      onoffA.SetAttribute ("OffTime", StringValue ("ns3::ConstantRandomVariable[Constant=0]"));

      onoffA.SetAttribute ("PacketSize", UintegerValue (payloadSize));

      onoffA.SetAttribute ("DataRate", DataRateValue (54000000)); //bit/s

      

      AddressValue remoteAddressA (InetSocketAddress (ApInterfaceA.GetAddress (0), port));

      onoffA.SetAttribute ("Remote", remoteAddressA);

      

      ApplicationContainer appsA;

      appsA.Add (onoffA.Install (wifiStaNodes.Get (0)));

      appsA.Start (Seconds (1.0));

      appsA.Stop (Seconds (duration + 1));

  

  // BSS 2

  

uint16_t portB (port);

      Address apLocalAddress (InetSocketAddress (Ipv4Address::GetAny (), portB));

      PacketSinkHelper packetSinkHelper ("ns3::TcpSocketFactory", apLocalAddress);

ApplicationContainer sinkAppB = packetSinkHelper.Install (wifiApNodes.Get (1));

      sinkAppB.Start (Seconds (0.0));

      sinkAppB.Stop (Seconds (duration + 1));

 OnOffHelper onoff ("ns3::TcpSocketFactory",Ipv4Address::GetAny ());

      onoff.SetAttribute ("OnTime",  StringValue ("ns3::ConstantRandomVariable[Constant=1]"));

      onoff.SetAttribute ("OffTime", StringValue ("ns3::ConstantRandomVariable[Constant=0]"));

      onoff.SetAttribute ("PacketSize", UintegerValue (payloadSize));

      onoff.SetAttribute ("DataRate", DataRateValue (54000000)); //bit/s

      

      AddressValue remoteAddress (InetSocketAddress (ApInterfaceB.GetAddress (0), portB));

      onoff.SetAttribute ("Remote", remoteAddress);

      

       ApplicationContainer appsB;

      appsB.Add (onoff.Install (wifiStaNodes.Get (1)));

      appsB.Start (Seconds (1.0));

      appsB.Stop (Seconds (duration + 1));
