wsn-ping.cc example

[Jaspal Singh]

Greetings!

I am new to NS, just downloaded NS2.35. I wish to use NS3 for simulating WSN. On browsing through the examples I came across example wsn-ping6.cc. Need help on few queries regarding the same:

I tried creating network with 100 nodes and allotted random positions to those (this was a minor change as listed below):

  mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel");
 
   Ptr <UniformRandomVariable> x= CreateObject <UniformRandomVariable>();
   Ptr<ListPositionAllocator> nodesPositionAlloc = CreateObject<ListPositionAllocator> ();
   int nodeCount, xPos, yPos;
   for (nodeCount=1; nodeCount<=100; nodeCount++)
   {
       xPos=((int)(x->GetValue()*1000))%100+1; yPos=((int)(x->GetValue()*1000))%100+1;
       std::cout << "Adding node at position (" << xPos << ", " << yPos << ")" << std::endl;
       nodesPositionAlloc->Add (Vector (xPos, yPos, 0.0));
   }
   mobility.SetPositionAllocator (nodesPositionAlloc);
   mobility.Install (nodes);
 

Now I wish to simulate Direct communication between nodes and the sink and I don't know how to proceed.

I understand this would require:
1. Creating a sink
2. Making the nodes send data packets to the sink after fixed time intervals
3. I also need to compute remaining energy after each communication.

Hi,

I'd suggest to start with the tutorial. It explains about all these things.

Cheers,

Thanks,

Tried searching ns3 tutorials for WSN, lr-wpan, but got no  results.

https://www.nsnam.org/docs/tutorial/html/search.html?q=lr-wpan

Sorry, but could you suggest some links.

All right,

On browsing through the tutorial, I see that these are  step by step explanation of the example scripts. I'll go through these before posting my next question.

Thanks.
