Error "uid<=m_information.size()&&uid!=0" in NS3-SUMO integration

[liangy...@126.com]

Hello groupers,

I want to integrate NS3 with SUMO with wifi used for VANETs simulation (the executed command was shown below). 

There was an error  "uid<=m_information.size()&&uid!=0, file type-id.cc, line 430" (see the figure below). 

I have checked the line 430 of file type-id.cc (see the figure below). I still can't solve this problem.

Could you please help me solve this problem? The codes is attached. Your help would be appreciated.

Best regards

It's better to simply copy the text from the console and paste it here instead of screenshots, because that makes it searchable. You can use click on the { } icon and paste code or console output.

You also want to use a debugger like gdb. You can do this:

1. sudo apt-get install gdb
   
2.  ./waf --run ProgramName --command-template"gdb --args %s"
   
3. You're now in the debugger (gdb) run <arguments> in my case I tried:

   run --traceFile=src/mobility/examples/default.ns_movements --nodeNum=2 --duration=100.0 --logFile=ns2-mob.log

4. then you can type "bt" to backtrack and see if the debugger points you to your error line.

It seems that you have a few issues. I usually initialize my wifi with default settings and then set the attributes I need. 

 YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

 wifiChannel.SetPropagationDelay("ns3::ConstantSpeedPropagationDelayModel");

 wifiChannel.AddPropagationLoss("ns3::FriisPropagationLossModel","MinLoss",DoubleValue(250));

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default ();;

wifiPhy.SetChannel(wifiChannel.Create());

Also ,you have a potential problem with your TypeId, I'd do something like this to have a UDP socket, for example. 

  TypeId tid = TypeId::LookupByName ("ns3::UdpSocketFactory");

and for the target address, don't put the IP string, the IP string might be off. A more reliable way to do this is

  //InetSocketAddress remote=InetSocketAddress(("10.1.1.72"),Port);

  InetSocketAddress remote=InetSocketAddress( i.GetAddress(sink_index) ,Port);

I hope this help. 

You gave me a hint to how to determine the node's position! I'll need that for my own work and I was looking for it and missed this example in NS3.

Hi liangy,

I face same problem here as you, here's the log :

'build' finished successfully (0.593s)

assert failed. cond="uid <= m_information.size () && uid != 0", file=../src/core/model/type-id.cc, line=430

terminate called without an active exception

Command ['/home/ubuntu16/IEEE-802.11ah-ns-3/build/scratch/mipv6-single'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

I would like to know how you solve this problem.

Regards,

Paranaditha

Hi S.M.

I see that you use EEE-802.11ah-ns-3 module.

Did you by any chance use the RAW config interface for dynamic parameter tuning ?
