Hello everyone!
I'm new in NS2, I installed ns2.35. when run code simulate handoff between wifi and wimax, I got some error:
Wrong Number of Arguments! No arguments in this topology
ns wifi_wimax.tcl seed gd_threshold shutdown

expected integer but got "(1)"
while executing
"exit (1)"
invoked from within
"if {$argc != 3} {
puts ""
puts "Wrong Number of Arguments! No arguments in this topology"
puts "ns wifi_wimax.tcl seed gd_threshold shutdown"
puts..."
(file "wifi_wimax.tcl" line 29)

Are there any missing tools? if right! please guide me!
thanks in advanced!

You need to read the documentation that came with the scripts/code you downloaded. It's plainly telling you that you have the wrong number of arguments...that is, it's needing 3 (and tells you that), and you're not GIVING it 3.

Give the script the correct arguments and it will run.

@designermp : Some information is missing :

1. The patch / the changes added to ns-2.35 . There are multiple wimax versions.
2. The OS you are using. Name, version, architecture, please.
.. This command will reply i686 or x86_64 : $ uname -m

The command for wifi_wimax.tcl is e.g. $ ns wifi_wimax.tcl 1 2 4

Not sure how much more clear it needs to be. The script is asking for 3 arguments...so give it 3. knudfl gave you an example in post #3...did you not read/understand it?

Re #5.
Do you mean this https://sourceforge.net/projects/mihnistns229/
i.e. NS-MIH-MULTI-CRITERIA.tar.bz2 for ns-2.29 ? No chance with ns-2.35 .

But you can install the identical functioning ns-2.29-nist-mob-022707.tgz + pmip6-for-ns-2.29-nist.patch to ns-2.29.3
http://www.linuxquestions.org/questi...-4175539795/#2
And then you can run all NIST examples, and also the examples in NS-MIH-MULTI-CRITERIA.

Currently the only supported OS for NIST is CentOS 6.9 - i386
http://ftp.funet.fi/pub/mirrors/cent...86-LiveDVD.iso
>> CentOS-6.9-i386-LiveDVD.iso

The Wimax for NIST isn't working, AFAIK. EDIT. See post #15.
EDIT. The issues concerns a pre patch for ns-2.31 .


Wimax : Suggest wimax-awg → wimax-awg26_ns235.patch.gz .
I.e. you can have as many ns-allinone-2.x as you want, installed at the same time.
But do never add any *PATH text to .bashrc . Not required.

Wimax build http://www.linuxquestions.org/questi...-4175523810/#6

thanks knudfl for guiding me!
this mean:
I have to install a new OS CentOS 6.9 - i386 as your link: http://ftp.funet.fi/pub/mirrors/cent...86-LiveDVD.iso
then install the identical functioning ns-2.29-nist-mob-022707.tgz + pmip6-for-ns-2.29-nist.patch to ns-2.29.3, Am I right?
what verison ns2 should i install? is ns2.29.3 right?

Re #8.

Yes. One choice only. CentOS 6.9 - i386.

If you insist in building the application yourself, it is ns-allinone-2.29.3.tar.gz .

This will do :
Install the package "nist-pmip6-ns_229-ubuntu12_i386", and no other ns2 is required.
The few files needed to run $ ns ($ ns229-nist-pmip6-el6) are included :
/usr/local/lib/nistmob/ns-allinone-2.29/{ lib/*/*, bin/tcsh8* }.

The examples are required : nist-examples-Oct2015.tar.gz
( Can be unpacked and can be run in any location in /home/[user name]/ ).

Link to the CentOS 6 package nist-pmip6_ns229-2-1.i386.rpm

Re #9.

Please see the edited post #9 : Must be ns-allinone-2.29.3.tar.gz : Typo edited.

yes! but this link https://drive.google.com/file/d/0B7S...ew?usp=sharing i can't access: limited right to access! can you give me another link?

Re #12. https://drive.google.com/file/d/0B7S...ew?usp=sharing

nist-pmip6_ns229-2-1.i386.rpm : I changed the access to "Public on the Web".

HOWTO install nist-pmip6_ns229-2-1.i386.rpm :

cd Downloads/
su [enter root password]
yum install ./nist-pmip6_ns229-2-1.i386.rpm

thank you for helping me!

Post #7 correction.

»» The Wimax for NIST isn't working, AFAIK.««

The "nist wimax" for ns-2.29 is working OK.

The issues I remembered was with a later ns-2.31 patch.
( wimax-pre041707-ns231 ).
