[ns] RED parameters in Misra Hollot paper
Hi, I am new using ns-2 simulator. To be sure I want to run RED in ns-2 to see the same results of (Hollot, Misra). Is there any written .tcl code for this paper. Moreover, if I want to introduce 40 http session in to the network what should I do? I am sorry for these basic questions best hakki
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.

The problem is that the packets that you are sending to A3 have an
incorrect
port address.
When you use
$ns connect $a1 $a2
then automatically all normal control packets sent by a1 have the
destination port of a2;
as a1 is not connected to a3 in TCL, you must set the port by hand in C++,
as NS will not do this for you, eg:
void myAgent::recv(Packet* p, Handler *h)
{
hdr_ip*iph = hdr_ip::access(p);
hdr_cmn *ch = hdr_cmn::access(p);
...
iph-saddr() = addr(); // (set my IP address)
iph-sport() = port(); // (set my source port)
iph-daddr() = nextHop_iaddr; // iaddr of n3
iph-dport() = nextHop_iaddr; // port of a3
regarding the iaddr comment: check
http://tagus.inesc-id.pt/~pestrela/ns2/ns2_haddr_tips.html
In my ns2_shared_procs.tcl utils tcl file, I introduce procs for all
possible conversions of each form, using the procs handle2iaddr,
handle2haddr, handle2id, etc.
you could also have debug this problem by:
- redefining the no-slot handler to invoke the run-time TCL
debugger;
- use the mash inspector to find exactly who are _o153, _o158, etc
(http://tagus.inesc-id.pt/~pestrela/ns2/ns2_debugging2.html)
If this helps you, please contribute the description of the problem and
the
solution, in your own words, to the NS2 wiki.

Subject: Re: [ns] Multiple connections to a single agent
I'm not sure I understand, and perhaps I've not adequately described what
I'm trying to do, so I'll try again using a semi-hypothetical scenario:
(Please keep in mind I'm new to ns!)
Suppose I've got the following topology:
N1 - N2 - N3
And three different agents, (A1,A2,A3) which have all been implemented
differently in C++. The basic idea is that I want these agents to
automatically communicate with each other...
In C++ I've written an A1::command() function that will 'send' sends an
IP
packet to the A2 agent. When the A2 agent receives this packet, it then
sends a packet back to A1, which then gets returned to A2 (basically a 3-
way
handshake). A2 should then automatically send another packet to the A3
agent by creating a packet, and inserting N3's address in the IP header.
(I'm assuming all of my agents and nodes know about the topology)
In TCL I've done this:
set n1 [$ns node]
set n2 [$ns node]
set n3 [$ns node]
set a1 [new Agent/A1]
set a2 [new Agent/A2]
set a3 [new Agent/A3]
$ns attach-agent $n1 $a1
$ns attach-agent $n2 $a2
$ns attach-agent $n3 $a3
$ns connect $a1 $a2
#$ns connect $a2 $a3 ;# if I do this, the handshake doesn't work
$ns at 0.0 $a1 send
When I run this, ns gives me this error:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o158: no target for slot 3
_o158 type: Classifier/Port
content dump:
classifier _o158
0 offset
0 shift
2147483647 mask
1 slots
slot 0: _o153 (Agent/A3)
-- Finished standard no-slot{} default handler --
Basically I want A3 to look at any or all packets send to N3. How can I
force this?
I'm using ns-2.29 on Mac OS X 10.4.7.
Thanks in advance!

no problem with tcp
you can do attach agent as many time as you want to a single node.
you must first define it as tcp-source. and then to choose the
application
which runs over this
tcp, for example i did it with FTP. moreover you can do it for n,
within
a
loop

Hello All,
I'm wondering if it's possible to have a single Agent connected to 2
or
more
other Agents. I have a topology similar to this:
N2

N0 -- N1 -- N3 -- N4
I have an agents A0, A2, A3 connected to N0, N2, N3 respectively, and
I
would like A0 to send a packet to A2, which would then in turn send a
packet
to A3. Is this possible?
From reading the mailing list archives, it seems like this may not be
possible, so my second question would be this:
Is it possible to attach an agent to a Node, and force that agent's
recv
function to get executed for every packet that passes through that
node?
For example: Could N2 send a packet to N4, so that A3's recv

[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 ?

[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.

[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? Thanks, -- Fernando Henrique Gielow - UFPR - NR2 Computer Science undergraduate student.

[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
