Hi knudfl,

Thanks for your reply. tracegraph is running. But, the throughput and delay output (From tracegraph) is not the same (from AWK-http://ns2blogger.blogspot.com.au/p/awk-scripting-on-ns2.html).
Can you tell me any link for proper measurement of throughput,delay for wireless LTE network?

Hi knudfl,

i want to use(insert) x graph/gnu graph function to view results, in following code that u gave me as lte example.

dear knudfl
i have already installed x graph it is also giving results but for particular code that i displayed in post 47.i need changes in that for graphs.

dear sir
i could not understand your requirements.what type of editing required
i am going to attach example lte code file in which i want to introduce x graph feature.i attached original "lte.tcl.txt" as well as "lte-xgraph.tcl.txt"

best regards

Re #50.

You are not supposed to show code as plain text. Don't do that again.
CODE TAGS, see http://www.linuxquestions.org/questi....php?do=bbcode
CODE Tags are : [code]tcl code text[/code]
I.e. type [code] at tcl code start, and [/code] at code end.
? What was problem with finding the 'Edit' button in post #47 ?


About Xgraph files : Please read and run all the default examples in :
xgraph_ns2-files-tcl_24Apr2015.tar.gz https://drive.google.com/file/d/0B7S...ew?usp=sharing
.... and read all the output files from the simulations.


Your file "hameed-lte.tcl" : Works OK. .... EDIT : Is a copy of eyana.tcl
( The name lte.tcl cannot be used. New files must have new unique names.)

Your LTE-Xgraph example : There is no such thing as "bytes" in ns2, AFAIK :
ns: record: can't read "bytes_": no such variable
********* Ref. **********
set bw [$server set bytes_]
$server set bytes_ 0
