NS2 Nam and Trace Files are always empty
 

Hi everybody,
I need help!
I wrote a script in which, a mobile node across the umts, the WIMAX and the WIFI coverage to test the vertical handover .
But the out.nam file and the trace one are always empty, the script is correct there is no errors !!!!
please help

Depends what you have written in the file.

? Are you sure that the finishing lines are :
$ns at 5.0 "finish"
$ns run
http://www.isi.edu/nsnam/ns/tutorial...s/template.tcl
http://www.isi.edu/nsnam/ns/tutorial.../example1a.tcl
http://www.isi.edu/nsnam/ns/tutorial/nsscript1.html

Suggest : Attach the file in question :
Use the paper-clip tool in the 'Advanced Editor',
and attach the file as name.tcl.txt .

.

I already verify it, my tcl code is complete !!!
this is the code, I couldn't attach the file I have always a Invalid File Error

Don't know which patching you have done with ns-2.xx (Unknown version.)
So I have no chance testing your file.

But :
Please read 25 random simulation examples.tcl : They all end with $ ns run


A ( tcl ) file must have suffix .txt added. See post #2 : file.tcl.txt

.

Sorry for the late, my NS version is 2.29 with ns2_NIST_mobility.patch
I already add "$ns run" in my piratical simulation

here is the error message
concerning the attach, I already change the extension of my file from .tcl to .txt but the error persists

problems with input data- trace file
 

hello

i download tcl script for wireless manet simulatioin ; it works fine for aodv, dsr and dsdv but whe using for
tora - nam file is created but when i run $xgraph tora1.tr it gives me error

hello knudfl,

i download tcl script for 3 nodes , i works fine for AODV, DSR and DSDV interms of nam file and trace file .
but when running the same script for TORA , it is simulated but when i run xgraph command at prompt as

$xgraph win.tr {where win.tr is a trace file for tora.tcl}

problems with input dta


please help me

Post # 5 : You are no supposed to change the extension from tcl to txt.
But to add .txt to file.tcl, so it's easy to actually see,
that it is a .tcl file. Like file.tcl.txt .

Post # 6 : Please show a direct download link to the file.
Or upload it to Google Docs / Google Drive.

Post # 7 : As for #6.

I.e. the code must be known for anybody to answer.
Not easy to answer about unknown code.
( We cannot guess what's in those files.)

hai knudfl

here i attach a link ( this was sent by u) , this code works fine for DSDV, AODV, and DSR that means it gives both .nam and .tr files but when i use this same script for tora , it creates 1_out.nam and 1_out.tr ; $nam 1_out.nam works fine but $xgraph 1_out.tr cannot give graph ; it displays "problems with input data"

http://ipsit.bu.edu/sc546/sc546Fall2...files/tora.tcl

please help me

hai knudfl,

please respond ,iam eagerly waiting for u,

i would like to simulate MANET routing protocols ; i run DSDV, AODV and DSR successfully but not TORA. u sent me a tora.tcl link it gives
successful nam but not trace file. with only trace file we can produce graphs.

please give me a successful tora.tcl file that must give nam file and trace file .


please ,please respond

hello knudfl

here i attach a tora tcl script , it gives nice simulation , but for this tcl script trace file is empty.
that is my problem...

please check this and provide me a successful tora tcl script that gives trace file for producing graphs

thank u

# 10

http://ipsit.bu.edu/sc546/sc546Fall2...files/tora.tcl :
I got the "ipsit tora.tcl" to work with no "eternal loop".
And '1_out.tr' , 133 kB is created. In the tora patched ns-2.34.
http://erl1.wordpress.com/2010/08/10...-ubuntu-10-04/
>>> " fix the line 504 (ns-2.34) in imep/imep.cc "


Your code in post #11 : Some typos. Edit all 'Set' to set.
Edit : Set val(prop) Propogation/TwoRayGround;#radio-propogation model
To : set val(prop) Propogation/TwoRayGround ;#radio-propogation model
Edit : Create-god $val(nn)
to : create-god $val(nn)
? May be there are more typos ?

Please edit post #11 to use "code tags", like the code in post #3.

hello knudfl

thank u so much for responding;
i was made changes to tora.cc , tora.h and also imep.cc after make changes to these ; i recompile my ns-2.34 as

$cd Deskto
$Dessktop\cd ns-allinone-2.34
$$Dessktop\cd ns-allinone-2.34\cd ns-2.34
$$Dessktop\cd ns-allinone-2.34\ns-2.34$make clean ; it is ok
$$$Dessktop\cd ns-allinone-2.34\ns-2.34$make ; after using make the following messages are displayed

make[1]: entering directory '/home/venkat/Desktop/ns-allnone-2.34/ns-2.34/indep-utils/cmu-scen-gen/setdest'
make[1]:nothing to be done for 'all'.
make[1]:leaving directory 'home/venkat/Desktop/ns-allinone-2.34/ns-2.34/indep-utils/cmu-scen-gen/setdest'
.
.
.
make[1]:leaving directory 'home/venkat/Desktop/ns-allinone-2.34/ns-2.34/indep-utils/webtrace-conv/ucb'
[venkat@localhost ns-2.34]$

what is the problem .

after these steps i run tora.tcl, it enter infinite loop;
may be the above statements are problem..
please help me

thank u

# 13
Means : Everything is OK.
I.e. all ns-allnone-2.34/ns-2.34/indep-utils/** were created
at the earlier ./install or make.
" indep-utils/" are separate applications, and they are not "cleaned",
when you do 'make clean'.


Please edit post # 11 to use code tags :
Write [/code] at code text end, and [code] at code start.
Or use the # button in the Advanced Editor.

hai knudfl
thank u so much for ur reply..
:'nothing to be done for all' if it is OK means then why tora.tcl enters infinite loop and does not work?
please help me ; tora is my research topic ..
thank u
