$0 ~/^s.* AGT/ {

        sendLine ++ ;

}



$0 ~/^r.* AGT/ {

        recvLine ++ ;

}



$0 ~/^f.* RTR/ {

        fowardLine ++ ;

}

  2. I mean running the awk -f file.awk file.tr gives error stating fatal division by zero when GPSR is used as routing protocol, but when aodv is used as routing protocol it works fine........... What can i do?

  3. @MyNs2 ,

    its work fine with GPSR (hope you are using gpsr and hls patch) protocol, Check the agent trace mode in your tcl script,

    -agentTrace ON

    it should be ON.

  4. Hi there,
    I'm wondering whether this script applies to new trace format or old trace format?
    I tried implementing it on a LEACH routing protocol tr file and I got the results, but the sent packets seem to be much less than the received packets.. is this output correct?
