it works Thank you so much.
After executing the .tcl file, I have two files .tr and .nam files. How do I know the results of the execution?
can you help me please?

Re #3.

"NAM file is a separate program which is distributed with NS2 simulator to read an input file and draw the network events graphically. It is used to visualize the progression of packets through the Network."

Simply do $ nam file.nam
NAM package examples https://www.linuxquestions.org/quest...-4175524760/#2
___________

Files.tr can be analyzed with e.g. an awk script: $ awk -f file.awk file.tr

I'm using the olsr protocol in an flying ad-hoc networks (fanets).
please, how can I make the nodes move and set the speed of the nodes?

shiyar · 07-20-2022, 08:47 AM

When I execute the tcl file in the olsr protocol and specify the number of nodes to 80 or more, it shows the following error:
Segmentation fault (core dumped)
What is the solution to this problem? Please help me.. thank you very much

Re #6.

`Segmentation fault´ happens more often when ns2 has been built with an "after year 2020 OS".
Critical code / old code is suggested built with an older ns2 friendly OS such as CentOS 6.10 .

`Segmentation fault´ can also be caused by a too complex simulation.tcl .
Or by expecting an impossible situation.tcl to run.

(#5) FANET → Geo3D :
The combined patch {umolsr-ns235_v1.0-2014.patch + geo+ns2-3D_ns235.patch-3}
.... is "Geo3D+olsr_ns235.patch"

Re #6

`Segmentation fault´
I get Segmentation fault with 80 nodes (Not with 50 nodes)
The example was DSR__routingprotocolforFANET.tcl edited to
New file name = o-80-OLSR__routingprotocolforFANET.tcl

Code:

set val(adhocRouting)  OLSR
set val(nn)            80
set val(stop)          50.0

.... but the trace files have reached reasonable sizes, so `Segmentation fault´ may be ignored.

50 nodes : o-50-OLSR__routingprotocolforFANET.tcl

Code:

set val(adhocRouting)  OLSR
set val(nn)            50
set val(stop)          100.0

Please read "TextFile__setdest3D" : Create movement file 3D with 'setdest3D'.

#Re 9
thank you so much but When I run the instruction, it appears:
setdest3d: command not found.
please, How can I create a 3D movement.

knudfl · 07-25-2022, 04:10 PM

Re #10

The supplied file is setdest3D, therefore the command starts with ./setdest3D
.... Alternatively you can rename to setdest3d and do ./setdest3d -options

I create a 3D movement But when I run the tcl file, the following error appears:

Re #13

Quote:

But when I run the tcl file

? Which file.tcl ? ?
... The most common error is a too small x y z setting ...

Code:

# default values
set val(x) 1000
set val(y) 1000
set val(z) 1000

Or a missing 3D setting ?

Code:

# setup topography object
set topo	[new Topography]
.
.
.
# define topology
$topo load_cube $val(x) $val(y) $val(z) 1

.... Or maybe you are using a wrong executable ?
COMMAND example

Code:

$ ns235-geo-olsr-64 o-50-OLSR__routingprotocolforFANET.tcl
$ ns235-geo-olsr-64 oz-19-estudy-Fanet.tcl  ## movement file: speed 50.000
