[ns] node overlap issue+relay node role
Hi!
Why the node are overlapped although I defined their co-ordinates.
Also how the relay nodes be configured so that they play active role during
communication, here what I am seeing that the source starts communication with
the sink directly without interfering with the relay node even you drag the two
to large distance... why?
I am seeking some useful help from yours side.
Thanks

[ns] TCP CC and RSVP source code
A new TCP scheme called Congestion Coherence was proposed and as well created by Chunlei et al. (2007). The researchers published a paper entitled as a A Unified TCP Enhancement for Wireless Mesh Networks . In that paper one can find the proposed TCP scheme known as CC. According to the findings of Chunlei et al. (2007) the new TCP enhancement CC performs well when compared with Reno, Vegas, DDA and ECN. Please help me locate a website that offers TCP CC source code or even patch. As well I need RSVP source code. *** Abduaziz Oumer M.Sc.IT Northern University of Malaysia Universiti Utara Malaysia (UUM) College of Arts and Sciences, Faculty of Information Technology, 06010 UUMSintok,Kedah, Phone:+60142276220 M A L A Y S I A

Re: [ns] CFT SyClick symposium on Click Modular Router
I just read a little about Click and it sounds really interesting. I have a project and I was thinking in using the default nodes of NS (adding later routing, classification, filtering, etc.) but now that I read about click I think it may be a better approach. There is a link in the Click's wiki in how to use it with NS-2, however I wonder if anybody has any more resources (presentations, tutorials, papers) about the use of Click and NS-2.

[ns] Installing Is-Is module on ns-2.33 : problem adapting C++ code to gcc 4.1.2
Hello,
I am quite new to ns and for a specific project I am doing my best to
install the Is-Is module on ns-2.33(the latest version).
Since the code has been written for ns-2.1b8a I manually patched
Makefile/Makefile.in, dynalink.cc, etc. Everything great.
But still, the module has a problem with my gcc 4.1.2 compiler on
CentOS. It uses C++ template classes and it seems that the code needs to
be fully adapted in order to work.
I am posting the error message I got:

[ns] wireless ad hoc network mobility nodel simulation in 3 dimension
Has any body tried to generate a mobility model in a 3 dimensional simulation area. I have been trying to modify the setdest.cc file in ns2, which is the default implementation of Random Waypoint Mobility Model in ns2, to generate my own mobility model. I want to set all X, Y and Z coordinates for the movement ofmy mobile nodes. Is it possible in ns2 to do that? Does nam has support for 3D visualisation ? Also can I use the movement scenario file generated as a result of this in my wireless simulation without any modification or will I need to change some other codes as well? Any help in this regard will be useful. -- Prateek Agarwal

[ns] Looking for 802.11b wireless support
Hi all, (sorry if you received multiple copies of the email) I'm a new ns-2 and trying to find a more realistic wireless support for 802.11b simulation, such as channel propagation model and link rate adaption (e.g. ARF). Currently my system is Ubuntu 7.10 + ns-2.33. Could anyone share your experience and give me some suggestions? I tried to apply the patch provided by Marco Fiore in the contributed code list (http://nsnam.isi.edu/nsnam/index.php/Contributed_Code#Wireless_and_Mobility). This patch is supposed to work with ns-2.29, but I have problem with the installation ns-2.29 on Ubuntu 7.10 (the same error report as http://ubuntuforums.org/archive/index.php/t-1050882.html). Does anyone have any idea how to solve the problem? I wonder if there is a patch available for newer version of ns-2. Please feel free to give your comments. Thank you for the help. Best, Jiakang
