wifi-clear-channel-cnu.cc gnuplot

[Saagar C]

Hello,

I am trying to simulate this example code. But when I try plotting a
gnuplot, i get an error saying,

DsssRate1Mbps
^
"wifi.dat", line 1: invalid command

My build was successful and I used the set of following commands:

$ ./waf --run wifi-clear-channel-cmu > wifi.dat
$ gnuplot wifi.dat

need some help in resolving this issue.

Thanks!

Ok, I see there is a "clear-channel.plt" getting generated after the
execution.
But the graph is incomplete. Can anyone take me further on this?

Thanks,
Sagar

Hi.

There are 2 common methods to make a plot using ns-3 and gnuplot:

1. Create a gnuplot control file using ns-3‘s Gnuplot class.
2. Create a gnuplot data file using values generated by ns-3.

If you are interested in method 1, see the “Making Plots using the
Gnuplot Class” section in the ns-3 Manual:

http://www.nsnam.org/docs/release/3.12/manual/html/gnuplot.html

If you are interested in method 2, see the “A Real Example” subsection
under the “Tracing” section in the ns-3 Tutorial:

Thanks Mitch!

I finally got to figure out how to plot this graph. But the
clear-channel.eps file which gets generated in the end shows that the
y-axis values are 0 all the time. i.e. the number of packets is 0 all
the time. Any remarks on that??

Thanks
Sagar

I don't know why.

oh, anyone?

the author of this code has resolved the bug... and one needs to "hg
pull" and "hg update" to use this...

Thanks!
