UDP Server and Client application with WiFi channels

[Ujjval Rathod]

Hi,

I have a simple schenario with a network which has one WiFi Access-point and Station.

A Station(Client) sends a UDP trafic to the Access-Point(Server). The following code is with two applications one of which is running on Client and another on the server. 

After I run the entire program I could see the packets are being transmittd but do not see them being received at Server. Anyone has an idea with WiFi based UDP configurations?

LogComponentEnable("UdpClient", LOG_LEVEL_INFO);

LogComponentEnable("UdpServer", LOG_LEVEL_INFO);

//Access Point app

  UdpServerHelper Server(9999);

  ApplicationContainer serverApps = Server.Install(wifiApNode.Get(0));

  serverApps.Start(Seconds(1.0));

  serverApps.Stop(Seconds(10.0));

//Station App

  UdpClientHelper Client (interfaces1.GetAddress(0), 9999);

  Client.SetAttribute("MaxPackets", UintegerValue(10));

  Client.SetAttribute("Interval", TimeValue(Seconds(1)));

  Client.SetAttribute("PacketSize", UintegerValue(1024));

  ApplicationContainer clientApps = Client.Install (wifiStaNode.Get(0));

  clientApps.Start(Seconds(2.0));

  clientApps.Stop(Seconds(10.0));

Hi,

I am still looking for a solution if someone has got an idea please let me know.

You didn't provide much details for me to pinpoint the problem, but my guess is that packets might be dropped because nodes do not have routing table, so maybe your code needs something like

Ipv4GlobalRoutingHelper::PopulateRoutingTables ();

So that routing tables are created.

Cheers,

Hi,

Thanks for your reply. 

I can attach the code for you. I have created the routing tables but still, it does not seem to be working.

Moreover, as I have said there are Server and Client apps running on the different nodes. Please see the attached image.

Sincerely,

Ujjval

Hello There,

I have modified your code a little bit and it seems to be working

Hi Mahdi,

Thanks for sharing. It was a while ago that I have written that code with ns3. I will look into it again. Use diff. from Linux to see the changes you have made!!

Regards,

Ujjval
