Hi!

I am new to NS3. I am implementing 'mobility' and 'OLSR' in a 200 node network. I modified first.cc and in the process, removed PointToPointHelper and everything that used it. (NetDeviceContainer, Ipv4Helper etc. too are removed)

If I receive the following error, what does it mean?

assert failed. cond="m_mainAddress != Ipv4Address ()", file=../src/olsr/model/olsr-routing-protocol.cc, line=292
terminate called without an active exception

Please respond

Hi,

it means that you should read the tutorial (and perhaps also some networking books, I'd suggest this).

You just tried to use an IP routing protocol without giving any IP address to the nodes.  

Success probability: unlikely.

Haha! Thanks for the feedback. I'd go through books as suggested.

When the program started, it showed some address as "102.102.102.102 for node1" or the likes. How did that come up when I didn't assign any?

I'm sorry for top-posting in my previous response.

Hi,

"102.102.102.102" is the default address (i.e., the one used for non-initialized addresses).

Any not initialized Ipv4Adress object will have this number.

Again, please complete the tutorials (and be sure to understand them).

Thanks, this answers my last question.

Again, please complete the tutorials (and be sure to understand them).

Sure, I'll be here again if I could not fix that Ipv4Address part, as you mentioned.

Thanks T,

I solved my issue this way:

// Assigning IP addresses...                                                   
  Ipv4AddressHelper ip;
  ip.SetBase("192.168.1.0", "255.255.255.0", "0.0.0.1");
  ip.Assign(staDevice);                                                           // 'staDevice' os of type 'NetDeviceContainer'
