[ns] Nist- Diuc controls the Uplink channel?
Hi, Using the example datarate.tcl, the source is the Subscriber Station or MN0. The frame is divided into 2, one for uplink another for downlink. The burst profile for the Downlink is the Downlink Interval Usage Code (DIUC). My question is, why the maximum data transfered changes after changing the modulation in the Downlink Channel, if the channel used is the Uplink controlled with the UIUC? And if the MN0 is the sink node, and the fixed node is the UDP source, it seems that the traffic also changes after changing the DIUC? Is possible to have differente modulations, for the Uplink channel and Downlink channel? Is there a command like [$wl_node set mac_(0)] set-diuc , to change the UL modulation? kindly, Tiago Junqueira

[ns] ns-2 installation problem
Hi ns users I am trying to install an older version of ns-2(ns-2.1b8) on cygwin 1.5.23 on a windows XP platform. I have installed all required cygwin components including gcc packages however i am getting the following error when installing ns. checking whether the c compiler gcc works ... no configure: error: installation or configuration problem: c compiler can not creat executables tcl8.3.2 configuration failed Exiting ... Could anyone help me on this Thanks in advance - Get the Yahoo! toolbar and be alerted to new email wherever you're surfing.
[ns] classifier:: recv
Hello again! I am really confused with the function Classifier::recv. Can anyone explain me what exactly this dunction does? I would be really very careful. If i understood well, when a packet arrives from the LL layer then it is being forwarded to the Address Classifier. There, what are the possible "roads" that the packet can follow? I am using DSDV routing protocol. If the node is the receiver of the packet, then it will be forwarded to the port classifier, right? If the node isn't the receiver then it will be forwarded through the default_target_ (pointer) to the DSDV agent, right? When will a packet be forwarded to the DSDV agent through the port 255 from the port classifier? (i don't understand exactly the usage of this port 255) Please, please reply!!!
Re: [ns] 802.11e TKN, little error. i give a nice website in return
Sincerely thanks for the responce Sven.
I still have the same error.
I set up the tcl/lan/ns-mac.tcl as follows:
if [TclObject is-class Mac/802_11e] {
Mac/802_11e set delay_ 64us
Mac/802_11e set ifs_ 16us
Mac/802_11e set slotTime_ 16us
Mac/802_11e set cwmin_ 16
Mac/802_11e set cwmax_ 1024
Mac/802_11e set rtxLimit_ 16
Mac/802_11e set bssId_ -1
Mac/802_11e set sifs_ 8us
Mac/802_11e set pifs_ 12us
Mac/802_11e set difs_ 16us
Mac/802_11e set rtxAckLimit_ 1
Mac/802_11e set rtxRtsLimit_ 3
Mac/802_11e set basicRate_ 1Mb ;# set this to 0 if want to use bandwidth_
for
Mac/802_11e set dataRate_ 1Mb ;# both control and data pkts
Mac/802_11e set cfb_ 0 ;# disables CFB
}
Should I follow these steps, step 7 seems to be very problematic
7. mac/wireless-phy.h:
change
enum ChannelStatus {IDLE, RECV, SEND};
to
enum ChannelStatus {IDLE, RECVING, SENDING};
mac/wireless-phy.cc:
replace all occurences of RECV and SEND (by RECVING and SENDING).
8. common/packet.h:
add
#define HDR_MAC802_11E(p) ((hdr_mac802_11e *)hdr_mac::access(p))
9. run ./configure; make clean; make depend; make in your ns directory
10. happy simulating :o) (e.g with the example script
../ns-x/mac/802.11e/multi_udpflows.tcl)
Sincere thanks and regards.

Re: [ns] How to use PATCH command in ns2?
Patch is an Unix/Linux/Cygwin tools, not a ns-2 tool. See this short manual: http://www.cpqlinux.com/patch.html It'll be useful for make your own patches in future.

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.

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
}

[ns] How to use PATCH command in ns2?
Hello all, I want to install a patch for ns2. My ns version is ns-allinone-2.29.2.tar.gz, my patch is ns2292-gcc410.patch. My ns is in the directory /home/wyt/ns-allinone-2.29, the patch is in the directory /home/wyt. I want to ask: what command should I use in order to install the patch successfully? I used the following commands but they did not work: cd /home/wyt/ns-allinone-2.29 patch -p0 /home/wyt/ns2292-gcc410.patch It seemed that the terminal stopped and I did not know what happened. Can anybody tell me how to use the PATCH command.? I read the mannual and still could not understand it, especially what p0 and p1 means. Thank you.
