Hello NS Users, Sven, Matthias, hilal, and Pepe
I managed to get rid of the dh_da dh_sa problems that I mentioned
in the previous post.
BUT the rest of the make errors remain.
I am worried now. Because this makes me think that I need to use a
different version of NS, because Pete Barbe had a similar problem
as seen at http://mailman.isi.edu/pipermail/ns-users/2004-December/
046055.html
Please tell me if I have to switch versions of NS. ???
Hi, the EDCA model was released for ns-2.28. Just download this
version of ns-2
(http://www.isi.edu/nsnam/dist/ns-allinone-2.28.tar.gz)
and install it. Afterwards, you can apply the EDCA patch.
Best regards,
Sven
I do not know how to switch versions of NS. This is because I am
new to NS.
Can someone please give me quick advice on how to switch
versions.
Is their a quick way???

initially I thought that i might have made mistake in make the
object file for mac-802_11e may not have been created, but when i
checked the mac directory the object files corresponding to all the
.cc scripts in the patch were present..
This relates to C++ stuff only. Tcl code is not compiled by make.
Thus, a successful make is not an indication that the Tcl stuff is
correct, too.
what shall i do?
Check all your tcl settings.
I guess that step 6 of the readme has not been applied properly:
6. add to tcl/lan/ns-mac.tcl:
if [TclObject is-class Mac/802_11e] {
...
copy settings of MAC/802.11
(which are contained in this file) into this section
and at an e at the end of the Mac/802_11 terms
...
Mac/802_11e set cfb_ 0 ;# disables CFB
}
Best regards,
Sven
please someone
help..
Can you please tell me how you overcame this, as I have the exact same
problem.

Enjoy, and regards from Ireland.
Re: [ns] error in multi_udpflows.tcl its urgent...
Hi,
the problem appears if the installation has not been 100 percent
successful wrt the tcl files. Please check all settings described in
README again, especially in Makefile.in, ns-lib.tcl, and ns-mac.tcl.

Re: [ns] TKN 802.11e and Wireless Channell Error Model
Hi, usually the Error Model is independent of the MAC itself. If the Error Model determines that a packet is erroneous, it just sets the error flag (struct HDR_CMN) of the packet. This field is evaluated by MAC and the (same) actions are taken in the 11e as well 11 model if the packet is marked accordingly. Actually, what kind of drops did you observe in the trace for the legacy model that do not appear for 11e? Are parameters for both models similar? If the settings are different ( e.g., 11a/b/g, RTS/CTS enabled or disabled etc.) also the packet loss rate might vary greatly.

Re: [ns] backoff decrement and transmission in 802.11e tkn code
On Mar 15, 2006, at 1:40 PM, Jongman Heo wrote: According to section 9.9.1.3 in the IEEE 802.11e standard, one and only one of the following actions is allowed at slot boundaries: - decrement of backoff timer, or - initiate transmission, or - backoff procedure due to internal collision, or - do nothing. So, 1. Backoff counter is resumed one slot time before the AIFS expiration. 2. However, since a single MAC operation per slot is permitted (backoff decrement or packet transmission), when the backoff counter decrements to 0, the station cannot transmit immediately, but has to wait for a further backoff slot if the medium is idle, or a further AIFS expiration if the medium is busy. Hi, exactly this has been included in the new EDCA model for ns-2.28. The updated backoff code can be found in mac-timers_802_11e.cc/h. Best regards, Sven I think that 802.11e TKN code is a good implementation of IEEE 802.11e. However, it seems that the implementation conforms to the requirement 1, but do not to the requirement 2. Am I correct? ps. The following paper can be a good guide.
