[ns] How to compile and run tcl files?
Hai, I have written some .cc and .h files in a folder GPW. In the same folder I have written gpw.tcl file. In makefile.vc and Makefile of higher directory I have included GPW folder in INCLUDES list. And I have included .o files at the end of OBJ_STL list. I am typing make to compile. It is compiling. Then When I type The command ns gpw.tcl, in the output I am not getting the changes that have been made. Even if I remove all .cc, .h, .o files( all files except gpw.tcl) in GPW folder and type ns gpw.tcl, I am getting the same output. The changes that I have made are not getting reflected. In SUMMARY, what is the normal way to compile .cc files that .tcl file requires and run the .tcl files? How shall we make necessary changes in Makefile? -Regards, Mallesh

[ns] segmentation fault
Hello all,
I wrote a new agent. this agent has a command{} which receives 6 arguments. I
used the following line to pass the arguments to the command{}.
$ns at $now $source-ad($j) ad-request $j $peak $error $standard-dev
but when I ran tcl script, I received this error:
segmentation fault. i know segmentation fault usually stems from illegal
access to the memory but i don't know how i should solve it.
can anybody help me about this error?any kind of help.
Thanks in advance
Regards
Elahe

[ns] Bit error models for NS-2
Hi, I would apprceiate if you could suggest references to implementations taht simulate wireless losses based on SNR. I mean an error model for Ns-2 that simulates BER Vs SNR graph. Any hint or idea would help. Thanks a lot, Raghu.

Re: [ns] How to add new C++ classes to NS-2 2.31?
You should make changes in some tcl files in the directory '.../tcl/lib/'. See the following link: http://icapeople.epfl.ch/widmer/uwb/ns-2/index.html In this link many changes are made to install new changes in the physical and mac layers of ns-2. Also a new propagation model (tarokh propagation) is also added. See what are changed in the directory '.../tcl/lib/' regarding tarokh propagation only (DO NOT MAKE the other changes of course). You will find the changes in patch.tcl.lib file that you can download from the link above. I hope that this will help you. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ghada Al-Mashaqbeh Sent: Mittwoch, 12.

[ns] TCP Transmission between 3 mobile nodes?
Dear all, I have three 802.11b mobile nodes (A.B.C), where A and C are hidden from each other. A sends TCP packets to B (start time = 1 sec) C sends TCP packets to B (start time = 1.5 sec) (end time for both transmissions = 10 sec) Judging by the trace file, I see that only A transmits to B all the way through the simulation (at the beginning C sends some Boradcast packets to B as well, but only 3 or 4 packets, and then it doesn't access the channel afterwards). Does anyone know why this happens? Why there isn't any collisions? This situation doesn't happen in UDP Transmission. I observed there are collisions between packets of stations A and C, (specially, using the Basic Method) which reduces the overall performance. So, UDP works well. Any ideas about the TCP transmission? Thanks, Bahman _ 100’s of Music vouchers to be won with MSN Music https://www.musicmashup.co.uk
[ns] About dei80211mr library
Dear all, I am using ns2 under windows xP SP2 using cygwin, when I have tried to install dei80211mr using the same steps on its website and after installing the dynamic library batch, I have faced the error that no dynamic libraries is supported on this system (when I have tested some examples). How can I make windows support such dynamic libraries? if there is no method can you help me to find other libararies that run under windows to make NS-2 support interference modeling and multirate capability which exist in dei80211mr?

[ns] Questions about patches added to ns-2.
Dear all, I have two questions related to the patch installations on ns-2: -- If I have more than one patch to install, must I install all of them at the same time or I can do that serially at different times? -- Can I have a confliction between batches that support common functionality? e.g. two batched supports multi interface capability, can I use any one of them or I mus have only one patch for this purpose? -- If I have a patch deisgned for a spcified version of ns-2 can I use it for another version? e.g. the MW-node patch for ns-2 2.30 can be used for ns-2 2.31? is thier any modification needed for this purpose?

[ns] Expponential traffic over SCTP
Hi, I´m working with SCTP in ns-2 and I have done some tests with Exponential Traffic over SCTP. I observed two things: 1 - Considering all Exponential parameters as default, it doesn´t work (segmentation fault caused by burtlen_setavg(ontime/interval_) instruction). I had need to change the interval_ parameter to 1 (default value is 0). But is it correct? Can it change the natural behaviour of Exponential traffic? 2 - The SCTP consider the Exponential traffic as a SCTP-aware application and not a legacy application. Is it correct? Has somebody any example that runs well? Some help or comments are appreciated. Tanks Elisabete Reis
[ns] How to recompile and run tcl files?
In SUMMARY, what is the normal way to recompile .cc files that .tcl file requires and run the .tcl files? How shall we make necessary changes in Makefile? I have tried make clean, make depend, ./configure, make. Even I tried ./install in ns-allinone-2.28 folder and then tried the above Make clean, ./configure, make clean, make depend and make commands. But still, I am getting the same old output. The changes that I have made are not getting reflected in output. When I keep some error in .cc file, when using make, it is giving me error. When I correct it, make is compiling successfully. Any help or suggestion is greatly appreciated. -Thanks and regards, Mallesh
