I have a problem in combining SpectrumWifi and lr-wpan

Dear friends,

I have a problem now, I am trying to combine spectrumwifi and lr-wpan to research inter-channel interference.

And now, my spectrumwifi is use adhoc-aloha-ideal-phy with  MultiModelSpectrumChannel and MatrixPropagationLossModel by udp to transport.

When I create lr-wpan nodes with Ipv6 and sixlowpan to transport packet in udp.

  uint16_t wsnport = 5000;

  UdpServerHelper server2 (wsnport);

  ApplicationContainer apps2 ;

  apps2 = server2.Install (wsnnodes.Get (1));

  apps2.Start (Seconds (0.0));

  apps2.Stop (Seconds (5.0));

  uint32_t MaxPacketSize2 = 127;

  Time interPacketInterval2 = Seconds (0.01);

  uint32_t maxPacketCount2 = 10;

  UdpClientHelper client2 (serverAddress2, wsnport);

  client2.SetAttribute ("MaxPackets", UintegerValue (maxPacketCount2));

  client2.SetAttribute ("Interval", TimeValue (interPacketInterval2));

  client2.SetAttribute ("PacketSize", UintegerValue (MaxPacketSize2));

  apps2 = client2.Install (wsnnodes.Get (0));

  apps2.Start (Seconds (0.0));

  apps2.Stop (Seconds (5.0));

Although it would build successed, but sending me messages,"Error while sending 127 bytes to".

how can I resolve this problem?

please give me some suggestions, thanks.

Thanks

Hi,

the error is from the UdpClient app, and means (basically) that the Socket is returning zero. This may happens for a number of reasons, but they all go down to the same root: the socket wasn't able to send the packet.

Why this happened.. I have no idea. The only decent suggestion I can give you is: use a debugger and good luck.

As a side note, you just made me remember that I have to submit my MultiModelSpectrumChannel patch for lr-wpan...

Cheers,

T.
