The only tcl script that I know "as working with 802.11e" is
``multi_udpflows.tcl´´ See mac/802_11e/multi_udpflows.tcl

EDCA + HCCA at the same time ?
Don't know. You will get an answer .... later. EDIT → →
→ EDIT : See post #79.

* You can keep all your ns-allinone installs :
I have more than a hundred times ns-allinone-2.xx.
And they all work OK.

The "multi_udpflows.tcl" is present in EDCA-802.11e_ns230.patch? cz the size of the patch is 153 Kb and no tcl file in it.
What should be the size of this patch?? cz all tcl files are present in ns2.35 . Are they the same for ns2.30??
Should i follow the same step as post #69? or the gcc and g++ are different than: CC=gcc-4.4 CXX=g++41?
im so thankful for all ur replies

← #77 .

$ tar xvf ns-allinone-2.30.tar.gz
$ cd ns-allinone-2.30/
$ patch -p0 < EDCA-802.11e_ns230.patch
$ export CC=gcc<?> CXX=<?> && ./install
$ cd ns-2.30/
$ cp ns ns230-edca
# cp ns230-edca /usr/local/bin/
.. Then you can hopefully do $ ns230-edca multi_udpflows.tcl
.. in ns-2.30/mac/802_11e/
.. or you can copy "multi_udpflows.tcl" to any location :
$ ns230-edca multi_udpflows.tcl

The patch EDCA-802.11e_ns230.patch is 152.3 kB : 155,924 Bits.

I have some problem!! when i wrote: $ patch -p0 < EDCA-802.11e_ns230.patch, the output is:
bash: /usr/bin/patch: Permission denied
So what i should have to do??
and another question is: is there any patch for HCCA suitable for ns2.30???

← #80 .

Permission denied : May be the permissions somehow were changed ?
Please try : $ chmod 0644 EDCA-802.11e_ns230.patch


Is there a patch for HCCA .. for ns2.30 :
HCCA is IEEE 802.11e. See post #79.
EDCA is IEEE 802.11e. So you cannot use both in the same ns2 :
Conflicts.

-

the output is : chmod: changing permissions of `EDCA-802.11e_ns230.patch': Permission denied. How can I solve it?
so if i have to simulate the QOS of IEEE 802.11, i should simulate EDCA and HCCA separatly, the first on ns 2.30 and the other on ns 2.29.
i cannot associated them in only one tcl. is it right????

← #82 .
May be you have handled the file with root ?
And changed the owner to root.
This will show : Please try, as root : # chown <user-name>:<group> EDCA-802.11e_ns230.patch
( In all Linux OS that would be, for "knudfl" :
# chown knudfl:knudfl EDCA-802.11e_ns230.patch ).

i am sorry for all my questions but i really need ur help..
i run the cygwin as an administrator and when i wrote: $ cp ns ns230-edca
The output was: cp: cannot stat `ns': No such file or directory

is it due to a wrong installation? how can i solve it?

← #84 .

I guess you now have now built ns-allinone-2.xx a few times,
and would know when the "./install" finishes OK, or not OK.

Short : If there is no executable by name 'ns' in ns2.30/,
it's a failed build.
? Are you sure you are in the right directory ?
If any doubt, the first command is always : $ pwd

-

in which directory should it be?ns-allinone2.30??

← #86 .

The executable 'ns' is created in ns-allinone-2.xx/ns-2.xx/,
like ns-allinone-2.30/ns-2.30/ns

Read post #78 :
$ cd ns-allinone-2.30/
$ patch -p0 < EDCA-802.11e_ns230.patch
$ ./install
$ cd ns-2.30/
$ cp ns ns230-edca

-

Yes im in the directory ns-2.30 but there is no ns directory in it

← #87 .

.... Better read posts #85 and #87


#85 : ... executable by name 'ns' in ns2.30/
#87 : ... ns-allinone-2.30/ns-2.30/ns
... Doesn't look like there's any text about a directory.
A directory would appear as " ns/ ".
* 'ns' is "a regular file".

*** If there is no file by name 'ns' in ns2.30/ ,,,
... then you have a failed build : The terminal will report any error.
Please try this : $ cd ns-2.30/ && make 2>&1 | tee make-log.txt
.... and the text file ``make-log.txt´´ will save the make process.

I ve got a new problem:
when i wrote:
$ patch -p0 < EDCA-802.11e_ns230.patch
the output is:
patch: **** can't open file ns-2.30/common/packet.h : Permission denied
However ive change the security option of the edca patch and packet.h because it gives me at first: permission denied
So the new output is:
patching file ns-2.30/common/packet.h
Reversed (or previously applied) patch detected! Assume -R? [n] . if i click n, the question will be asked for all the files

patch: **** can't open file ns-2.30/Makefile.in : Permission denied
ive changed the security of all the ns-allinone file, the new output:
patch: **** can't open file ns-2.30/tcl/lan/ns-mac.tcl : Permission denied (the security of this file is full control)
what is the real problem ???
