[ns] Tuning transmission power
Hi all, I'm a (very)new user of ns2. I have to implement a mac protocol based on csma which is able to change the transmission power (and so the transmission range) dynamically. Can I do it by simply putting tcl commands such as the following one? $ns at 0.2 $node_(0) set TxPower_ 8.5872e-4 If not, I have to change the c++ code of ns2 in some way? I have read a lot of manuals and tutorials, but I didn't understand what I have to do.. Thank you in advance for the help francesca

[ns] Installation problems of nist module on ns-2.29
Dear ns2 users, I am trying to install the nist module--mobility packet for ns2 on ns-2.29. I download the packet from official website and replace it with the original ns-2.29 and did following: 1. ./install 2. recomplied: make clean 3. ./configure 4. make After that the original examples can be executed without any problem, but when I run the example testMIH.tcl, it didn't work and the error message shows invalid command name `agent/ND`... Any information regarding this will be really appreciated. Thanks in advace. Best regards, Ying HOU

[ns] why only smaller simulation scenarios working in aodv?
hello I'm currrently working on topic related to Preemptive Routing in AODV. I written c++ code in ns2 to achieve this. Problem is that simulation works fine for smaller topologies only(upto 10 nodes). If I run larger simulation scenarios(30) it is giving segmentation fault. why its not giving error for smaller scenarios and error for larger ones? Thanks in advance sri -- View this message in context: http://www.nabble.com/why-only-smaller-simulation-scenarios-working-in-aodv--tf3840285.html#a10873427 Sent from the ns-users mailing list archive at Nabble.com.
[ns] Energy and IEEE802.11
Hi, I have a question regarding the energy model of ns-2. When a packet is sent over IEEE 802.11, there is an exchange of Request-to-send/Clear-to-send (RTS/CTS) Messages. Are those actually simulated as packets in ns-2? I am asking, because I am wondering, whether the energy-use of such mechanisms is correctly mirrored in ns-2. The documnetation on the energy-model in the manual is quite brief... Thank you in advance. Best, -Matt

[ns] Problem with make
Hi, I have developed a new wireless protocol using ns-2.30, i have made all the necessary changes to the various ns files along with the makefile.in. But when i'm trying to #make, i get the following error. make: *** No rule to make target `tcp/tcp-qs.o', needed by `ns'. Stop. Does anyone have any idea on how to fix this??? Tnx Dimitris

[ns] New 802.11 Node Movement
Hi, all,
I am using the [new 802.11] from http://yans.inria.fr/ns-2-80211/ to
simulate.
I tried to use setdest in my tcl script, but I got some error message like
below:
==
ns: _o15 setdest 10.0 40.0 5.0:
(_o15 cmd line 1)
invoked from within
_o15 cmd setdest 10.0 40.0 5.0
invoked from within
catch $self cmd $args ret
invoked from within
if [catch $self cmd $args ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error error when calling class $cls: $args $...
(procedure _o15 line 2)
(SplitObject unknown line 2)
invoked from within
_o15 setdest 10.0 40.0 5.0
Then, I used for loop to call set-position function by second until the
node moves to the destination.
In this way, the node will move like jump to the destination, not smoothly.
Is there any way to make the node move smoothly to the destination,
especially in this new 802.11 model?
Thanks.

Re: [ns] Energy and IEEE802.11
Matt, hi. I think you're right. RTS and CTS are simulated as packets in ns-2.But I don't know what it has to do with the energy model. These packets are transmitted at the basic rate, and MAC_RTSThreshold is used to control the power threshold used to receive RTS . wish you good luck with your work. Cai Jie
Re: [ns] Problem with make
- Hi. I think that the problem that make reports has to do with the fact that all the previously object files exist. You could erase the object files of the .c files that you have modified so that make will have to rebuild only these files and not all of ns. On the other hand, if this doesn't work you can also issue the following commands, but in this case all of ns will be rebuilt, along with your new files. Consider it as a desperate measure: /configure --with-tcl=the-tcl-directory --with-tcl-ver=the tcl version \ --with-tk=the-tk-directory --with-tk-ver=the-tk-version \ --with-otcl=the-otcl-directory --with-tclcl=the-tcltcl-directory \ --with-perl=the-perl-directory --with-tcl-debug --enable-debug; make clean; make depend; make; Hope that I have helped.
