[ns] How to implement a new Protocol in NS2?
Hello, I'm a beginner in NS2 and have tested to implement a new example Protocol in NS2, using the Tutorial: Implementing a New Manet Unicast Routing Protocol in NS2 masimum.dif.um.es/nsrt-howto/pdf/nsrt-howto.pdf I did all changes who are necessary but I can't use this new Agent in a simple Tcl Script in the way like this, because I get the error message invalid command name: . . . set p1 [new Agent/TestProt] $ns attach-agent $n2 $p1 . . .

Re: [ns] how can we echange variable between layer???
If you pass these between c++ modules by calling TCL procedures, this is very easy (but slow) Start by checking this page http://tagus.inesc-id.pt/~pestrela/ns2/ns2_tips.html#_Toc124667331 Pedro Vale Estrela -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bilel Romdhani Sent: terça-feira, 10 de Outubro de 2006 11:47 To: Ns-users@ISI.EDU Subject: [ns] how can we echange variable between layer??? hi everybody, i m using ns2.27 to simulate wireless scenario and i want to know how can we echange variable between layer, ie, i want to use the cw_ variable on the droptail.cc file how can i do that if it's possible of course! thanks a lot

[ns] BIC TCP / CUBIC TCP under ns-2.29
Hi all, Anyone have installed BIC TCP and CUBIC TCP under ns-2.29 ? I have downloaded files (tcp.cc and tcp.h) from their site but they are for ns-2.26. Now, I need to make changes to my files in ns-29, since I cannot JUST use ns-2.26 files. I have downloaded ns-2.26 from NS2 site, find tcp.cc and tcp.h files and compare them with those downloaded from CUBIC site by using #diff tcp_226-nomoduls.cc tcp_cubic_226.cc diff_cc_files.txt #diff tcp_226-nomoduls.cc tcp_cubic_226.cc diff_cc_files.txt Result is to many changes to be made. Now, I don't know what to do. Am I missing something here ? It should be simple to install a modul.
[ns] reproducing the graphical results of EDCA model

[ns] How to implement aggregation?
Hi Everybody! I have to build a hierarchical network and then apply aggregation to it, i already have the tcl scripts for the building the network, what i need to know is, which C++ files do i need to change to implement the aggregation? i mean how does one know what files to change in the ns modules to add your own functionality. My project is to make a hierarchical network,not just one but its like a 1:1 dual, 1+1 dual, 1:2 dual and 1:4 dual networks, i already have the necessary files to build these networks, the next step is to implement aggregation over these networks, and i do not know where to start from? Please help any guiding step would be really helpful. thanks a lot in advance. Thanking you Regards, Fatema.

[ns] NS2 + UCBT
Hi list, sorry for this message. I know this is not the apropriate list for discussing external NS modules, but the UCBT list seems to be no more active, and I hope there are people here with some experience with UCBT. Well, I have reproduced, using NS2 + UCBT, a scenario whose I have performed some tests using real bluetooth devices. The problem is that the behavior presented by UCBT is rather different from the behavior verified empirically. Does anybody can help me with some hint of where, and how, should I modify UCBT for modeling the bluetooth features I need to deal with?? Thanks in advance! Loreno
[ns] generic VBR Traffic - bit rate higher than the maximum rate set
Hi, Has anyone try using the generic VBR application made by Håkan Byström? The source can be found here http://mailman.isi.edu/pipermail/ns-users/2001-October/018453.html I understand this code will vary the time interval which packets are sent as well as the packet size. Application/Traffic/VBR set rate_ 16Kb . . . Application/Traffic/VBR set maxrate_ 32Kb; The highest data rate for my simulation run is higher than the maxrate parameter. Is this normal? I think maximum rate should be below than the max rate. If it is not normal then there is a flaw in my translated code.Btw,I'm using a Java based network simulator. Comments are appreciated.
