Hi Guys, Good Morning I am trying to visualize cwnd plot in gnuplot in obuntu 10.04. I want to see the sawtooth display in time(x-axis) and packet (y-axis) but instead I am getting a different waveform. Can some body modify it according to sawtooth waveform. I shall be grateful. Below is my code: set ns [new Simulator]
$ns color 1 Green set tracefile1 [open out.tr w] set winfile [open WinFile w] $ns trace-all $tracefile1 set gio [open out.nam w] $ns namtrace-all $gio proc finish {} { global ns tracefile1 gio $ns flush-trace close $tracefile1 close $gio exec nam out.nam & exit 0 } set n0 [$ns node] set n1 [$ns node] $ns duplex-link $n0 $n1 0.2Mb 500ms DropTail $ns duplex-link-op $n0 $n1 orient right set tcp [new Agent/TCP/Reno] $ns attach-agent $n0 $tcp $tcp set fid_ 1 set tcpsink [new Agent/TCPSink] $ns attach-agent $n1 $tcpsink $ns connect $tcp $tcpsink set ftp [new Application/FTP] $ftp attach-agent $tcp proc plotWindow {tcpsource file } { global ns set now [$ns now] set time 0.01 set cwnd [$tcpsource set cwnd_] puts $file "$now $cwnd" $ns at [expr $now+$time] "plotWindow $tcpsource $file" } $ns at 0.01 "plotWindow $tcp $winfile" $ns at 0.0 "$ftp start" $ns at 5.0 "$ftp stop" $ns at 5.5 "finish" $ns run
