AODV routing protocol implementation

[Marcin Dorecki]

Hello,

I am trying to add AODV routing to my script. I am using the structure like this:

 MobilityHelper mobility;
  mobility.SetPositionAllocator ("ns3::GridPositionAllocator",
                                 "MinX", DoubleValue (0.0),
                                 "MinY", DoubleValue (0.0),
                                 "DeltaX", DoubleValue (grid),
                                 "DeltaY", DoubleValue (0),
                                 "GridWidth", UintegerValue (10),
                                 "LayoutType", StringValue ("RowFirst"));

  mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel");
  mobility.Install (sta);
 

/* ===== Internet stack ===== */
AodvHelper aodv;
InternetStackHelper stack;
stack.SetRoutingHelper (aodv);
stack.Install (sta);

  Ipv4AddressHelper address;

  address.SetBase ("192.168.1.0", "255.255.255.0");
  Ipv4InterfaceContainer staIf;
  staIf = address.Assign (staDevices);

But I get the error like this
' Build failed -> task in 'wifi_qos' failed (exit status 1):
    {task 139665919679760: cxx wifi_qos.cc ->wifi_qos.cc.1.o}

Without AODV routing the program runs without any problems. Thanks in advance for your help.

Hi,

too few compilation error lines shown. Please attach the offending script or more terminal lines.

Cheers,

T.

Hi,

I attach the script. The error:

Hi,

the two errors you posted seems to be different. One is a compilation error, and should leave you with no executable binaries. The second is a segmentation fault, caused by a bug in a compiled script. If you really had the first one, you couldn't even ran the program in the second.

Beside these errors, you have the following issues.

- First, it seems that you are using ns-3.17, i.e., a version dating more than 2 years ago. Please move to the latest version (we are at 3.23 right now). We can not provide help on outdated ns-3 versions.

- Second, you are using a even OLDER script. The line #include "ns3/simulator-module.h" clearly shows that the script was made for an extremely old ns-3 version. Please use the examples shipped in the current ns-3.

You can use the old script as a guideline to modify the examples, but expect different results. Bugs closed and features added are leading to more precision and different results.

Moreover, please take your time to read the tutorial and manual.

Have fun,

T.

Hi Tommaso,

thanks for your help. Unfortunately due to the implementation of 802.11aa in my distribution of ns-3.17 I have to work on it and cannot change to any newer version as for now.

The first error I posted is not valid any more- old header files were causing it most probably. now I have the second error- 'Command ['/home/mdorecki/Repos/ns-allinone-3.17_wifi-patches_simple-dot11aa/ns-3.17/build/scratch/wifi-qos', '--nSTA=3'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").'

Once I run it with debugging I get following output : ' Traceback (most recent call last):

As i mentioned before, without AODV script works as expected and I implemented AODV according to the examples found, any help will be appreciated

Hi,

as stated before, we can not provide any help on outdated ns-3 versions, and this statement is even more valid for an ns-3 version patched with unknown (to us) code.

It's not that we don't want to help, it's just that we really can't. How could we find a bug in something we don't know ? Logic, please.

The only suggestion I can give is: double check what you wrote and your "error" when you run the debugger. You're trying to use gdb and the command to launch it failed miserably (it's a python error). Triple check to have gdb installed properly and to have used the right command template.
