Receive at specific wifi interface

[Durgesh Kshirsagar]

Hello everyone!

I am working on a simulation where my need is as below:

1. There are some normal nodes and special nodes (Contains one base station).

2. Normal nodes have 802.11n wifi interface with 10.0.0.0 network

3. Special nodes and Base station have 802.11n (10.0.0.0)and 802.11ac (192.168.0.0) wifi interfaces

4. Special nodes collect data from normal nodes over 802.11n and send it to the Base station through 802.11ac

5. How can I send data from Special node to the Base station on 802.11ac.

Below is my code snippet where node 0,1 are special nodes and node 2 is Base station.

Ptr<UniformRandomVariable> x = CreateObject<UniformRandomVariable>();
TypeId udp_tid = TypeId::LookupByName("ns3::UdpSocketFactory");
Ptr<DtnApp> app[nodeNum];

for (uint32_t i = 0; i < nodeNum; ++i) { app[i] = CreateObject<DtnApp>(); app[i]->Setup(nodes.Get(i)); nodes.Get(i)->AddApplication(app[i]); app[i]->SetStartTime(Seconds(0.5 + 0.00001 * i)); app[i]->SetStopTime(Seconds(duration - 10)); Ptr<Socket> dst = Socket::CreateSocket(nodes.Get(i), udp_tid); char dststring[1024] = ""; sprintf(dststring, "10.0.0.%d", (i + 1)); InetSocketAddress dstlocaladdr(Ipv4Address(dststring), 50000); dst->Bind(dstlocaladdr); dst->SetRecvCallback(MakeCallback(&DtnApp::ReceiveBundle, app[i])); if(i==0||i==1||i==2) { Ptr<Socket> dst1 = Socket::CreateSocket(nodes.Get(i), udp_tid); char dststring1[1024] = ""; sprintf(dststring1, "192.168.0.%d", (i + 1)); InetSocketAddress dstlocaladdr1(Ipv4Address(dststring1), 50000); dst1->Bind(dstlocaladdr1); dst1->SetRecvCallback(MakeCallback(&DtnApp::ReceiveBundle, app[i])); } Ptr<Socket> source = Socket::CreateSocket(nodes.Get(i), udp_tid); InetSocketAddress remote(Ipv4Address("255.255.255.255"), 80); source->SetAllowBroadcast(true); source->Connect(remote); app[i]->SendHello(source, duration, Seconds(0.1 + 0.00085 * i), 1); char srcip[1024] = ""; sprintf(srcip, "192.168.0.%d", (i + 1)); Ptr<Socket> recvSink = Socket::CreateSocket(nodes.Get(i), udp_tid); InetSocketAddress local(Ipv4Address(srcip), 80); recvSink->Bind(local); recvSink->SetRecvCallback(MakeCallback(&DtnApp::ReceiveHello, app[i])); }

Output is like:

Finished the simulation!

I am not able find the error in above code. And it is clearly visible that 192.168.0.0 is receiving fron 10.0.0.0 where 192.168.0.0 should receive from 192.168.0.0 network.
