[ns] Help: creation of clusters in ns-2
Hi friends, I am new to ns-2 and I want to implement the hybrid routing protocol on ns-2. I need to create topology with two clusters with 4 nodes each. So please any body know how to create cluster in ns-2, please send me sootion or link where I will get the details about it. Thanks in advance Laxmi (laxmi@gmail.com)

[ns] reg. wireless scenario; making nodes compete for bandwidth with FTP application
Hi friends, please help me understand how to proceed conceptually with the following problem : I am trying to simulate the following scenario : There is an access point and multiple nodes in a wireless scenario. The nodes are not mobile. When the number of nodes connected to the access point are increased, I want to see how the total bandwidth available is shared between different wireless nodes : that is, I want to see the change in throughput as the number of nodes increase. Q1. For this purpose, I have Access Point as TCP source and rest of the nodes as TCP sinks. I have a FTP application attached to each of these TCP connections. Am I right in doing so ? Should I have it the other way?(Access Point as sink and nodes as TCP sources) Q2. In order to make each node really 'compete' for the total available bandwidth, what parameter concerning the FTP application(or TCP connection ?) should I change? Thank you very much ! Karthik

[ns] Help regarding absurd memory usage
I am simulating a protocol which I developed, and I wanted the simulation to end only when all my nodes are dead. Well, that is not really that fast to happen, and before I reach that point my memory ends and I get a bac_alloc error message. And here is the thing: I do alloc lots of packets with allocpkt, and I also always manage to free them with Packet::free(Packet *), but even when I free them, the memory usage don't even change ! And I am not overreacting when I say this, I made some experiments, and the average memory used when freeing all packet was exactly the same of when I did the same simulation withou freeing them. What do I need to do when I intend to have huge simulations, with like 15000 packets flying in the air? Using Packet::free didn't solve my problem. I even tried editing this function and inserting "free(pkt);" in its end, but it was in vain. Can someone please help me?

[ns] UMTS-WIFI Handover using NIST module
Hi, I´m working in a project about interoperability between technologies (WIFI,WIMAX,UMTS) and deploying some scripts to test this scenarios in NS (Network Simulator).

[ns] UMTS Code EURANE Code - Class Simulator Error
Hi Everyone! With Pats help I managed patching EURANE in NS-2.30 (OS: Linux). I am now trying to run test_tcp.tcl available on EURANE website. It is not executing correctly. I tried running each command of the program one by one to see wheres the error. Everything is OK till I reach... set rnc [$ns create-Umtsnode] which gives error: Error when calling class Simulator: create-Umtsnode Rest of the statements of the program are running OK (by that I mean there are no errors when I execute them) Can some one help me at this please? I am in desperate need of help!!! Faraz

[ns] Re : New protocol added..but error in running tcl script
hi,
to solve this problem, after make, you should execute make install , and your
protocol will work fine.
hope this helps.

Objet: [ns] New protocol added..but error in running tcl script

Hello everyone...
I have added a new protocol in ns2,which is an extension of aodv.
After making the required changes in all the files,running ./configure and
make goes well...
But if I run a tcl script using that protocol it shows an error :

[ns] Using mac 802.11e tkn with mac 802.11
Hi all,
I have installed the TKN package on ns-2.31 and it is working perfectly.
I'm asking if it possible to use both mac, 802.11e and 802.11, in the same
scenario to have a pair of node in EDCA mode and a pair of node in EDCF mode.
A scenario like this will works fine ?

Re: [ns] Multiple connections to a single agent
Hi, I need a help about RED in ns-2. I want to see the results in Hollot
Misra Infocom paper. In their paper, they introduced 60 TCP flows and 180
http session. I am so new about ns-2 so I don't know how should I introduce
these sources, especially http session.

You have two options. 1) Download ns-2.30 and patch with existing eurane patch. If you need something introduced in later versions of ns-2, you cannot use it. 2) Patch an existing ns-2.33 with the eurane patch for ns-2.30. This could result in difficulties which you must manually resolve. The patching procedure is documented in the manual, section 2.3. A patch is distributed in something called a diff-file, hence the file extension .diff. Gzip then adds the extension .gz. Before pathing the .diff.gz file needs to be uncompressed using gunzip. The result will be the diff-file. > Anyway, when I download and open eurane1.12.diff.gz, it gives an > error "associated help application does not exist"! This patch is > available for NS-2.30, I am using 2.33. What gives an error? A patch file should not be "opened", see the eurane manual for correct usage, or the patch man page, or google for "unix command patch" or similar. > Also, what is CLEAN NS-2.3 A clean version is a version not messed up by changes, builds etc. A fresh downloaded version is a clean version. > I downloaded test_tcp.tcl (UMTS implementation on NS-2 test run), > without installing any patch on my existing NS-2.33.
