Simulation of Wireless Sensor networks.

[abou...@gmail.com]

Dear all,
i need to simulate a wireless sensor networks.
the simulation scenario is to create a number of nodes ( 100 nodes).
All nodes must to send data to the sink.
i need to know how to create a loop that all nodes send their data packet to the sink.
the bellow is an incomplete sample of my source .
Have you please any idea.
Many thanks in advance.

LrwpanWirelessNode1     --->   Sink       <-----    LrwpanWirelessNode2
                                                |
  
     .......                          LrwpanWirelessNode100........

         UdpServerHelper udpServer(6000);
         //The Destination: Mobile Node
         ApplicationContainer apps = udpServer.Install (Sink.Get(0));
         Ipv6Address remoteHostAddr = i3.GetAddress (1,1);
         UdpClientHelper udpClient(remoteHostAddr, 6000);


         udpClient.SetAttribute ("Interval", TimeValue (Seconds(inter_Packet_Interval)));
         udpClient.SetAttribute ("PacketSize", UintegerValue (packetSize));
         udpClient.SetAttribute ("MaxPackets", UintegerValue (maxPacketCount));



         //The Source: The WirelessSensorLrwpan nodes
         ApplicationContainer apps2 = udpClient.Install (WirelessLrwpan.Get(0));// Here i need to create a loop to create that each WirlesseLrwpanSensor node send each own data packet

         apps.Start (Seconds (30.0));
         apps2.Start (Seconds (30.0));
         apps.Stop (Seconds (300.0));

Yes, the idea is: start by reading the tutorial and explain what the problem is.

From the description you gave, I see no problem whatsoever, except (maybe) the fact that you don't know how to get the most out of the WSN.

Cheers,

T.

Thank you Prof Tommaso for your Response,

My probleme is how to create a loop to install the udp applications on each node.

thank you.

What about a "for" ?

I'm sorry, but I still don't understand the problem. We can help you with ns-3, but you must have already some basic C++ knowledge, and if you don't know how to make a loop, then the problem is elsewhere.
