GetSystemId() for Nodes : Returns Result 0 for all nodes

[prajakta lokhande]

Hello,

My code for getting systemid of nodes in NodeContainer is as below

 for (NodeContainer::Iterator j = endDevices.Begin ();

       j != endDevices.End (); ++j)

    {

      Ptr<Node> node = *j;

      uint32_t systemid = node->GetSystemId();

      NS_LOG_INFO ("Systemid: " << systemid);

      

    }

The code returns value 0 for all nodes.  

I expect it to different so that I can identify each node with its SystemId.

Please guide me on this topic.

I have attached screenshot of my result.

Thanks and Regards
