[ns] Why authers dont give variation like 5 ms to 3000 ms in end to end delay simulations.???
HI all, When i simulated the AODV, DSR and DSDV, I found the end to end delay varies from 4 ms to 3000ms (approx). But in all the papers, those who are giving the comparison of routing protocols never shows such type of variation. Can u help me?? jeevesh kumar - Jiyo cricket on Yahoo! India cricket Yahoo!

[ns] R: Re: R: which trace format is more accurate?
Sasan,
I see your point.
How much do differ results you got in the two
cases?
By exact same simulation you mean that you simply
changed the
trace format and nothing else (included
the machine you working on)?

which trace format is more accurate?
Marco,
I agree that I need
separate awk scripts for different trace formats but
the particular
example that I gave below is straight forward
$1~/s/ /AGT/ {
sent ++; }
and should return total number of sents message in a
simulation and that
still returns different values (unless this is not
the correct way to
calculate the total sent messages)
what do you
think?
Thanks,
Sasan
Sasan,
both versions of
tracefile report the same information.
The
difference only lies
in the format (actually, the
new trace format is
somehow more
complete).
So they are accurate in the same way, but the
point
is that you can't use the same awk script on both!
You have to
write two versions of you awk script,
and then you'll get the same
results.

Marco Fiore

Hi All,
I am

[ns] Diffusion API doubt
Hello, I have a small problem, i.e., how will Diffusion API decide which node will be the next to send the interest. Lets consider that the initially interest is disseminated by node1 and say within the radio range of node1 are node2,3,4 which get the interest from node1. Now say node2 is the first to disseminated the interest to its neighbors, now my question is how is that node2 is selected for disseminating interest but why not node 3 or 4 although say node 3 and 4 are close to node1 but node 2 is far from node 1. Well how will this Diffusion API select which node will send the next set of interest when all the 3 received at the same time from node1. Waiting for reply. __ Do You Yahoo!? Tired of spam? Yahoo!

[ns] When does packets learn source and destination mode IDs.
Hi, I have been investigating NS2 for research purposes for the last several weeks. I have a very basic question and would really appreciate if someone could shed some valuable light on it. I really stepped through each line of the code but can't really find when and where the simulator assigns source and destination node addresses to the packets. Could someone please explain in some detail how, when and where the packets are assigned source and destination node addresses and from where does the packets learn this information? Also, if there are more than 3 nodes (in case of ping agent), how does the packet establishes the source and the destination nodes for traffic because in the Tcl script we only connect the agents and do not specify the source and destination nodes. Secondly, function access (some argument) is spread all over the code. I went through the manual as well but can't really understand why it is being used in so many places. Could someone please explain what is the purpose of using this function and how does this function when cast into different data types provides information? Thanks, - Faisal Siddiqui

[ns] Ping over LAN missed packets
Hi all,
I have been doing simulations on ns2 in the past weeks, and I have some
questions to our experimented community. I would appreciate your help.
1. I have this scenario:
* A Local Area Netwotk with 4 nodes.
* There is a Ping Agent on node 0, sending ping packets to node 2.
* I sent 100 ping packets (echo request) to node 2; on node 2 only 97 ping
packets are received.
* Because the latter, only 97 echo reply are received on node 0.
As you can note, there are 3 ping packets missed, and the simulator does not
reflect that.
Packets 29, 66 and 68 are never received on node 2.
This is my ns2 script. It is commented in Spanish. I send ping packets
following an exponential distribution.

[ns] HFSC queuing
Hello, I am doing research in comparing CBQ to HTB and HFSC. Both HTB and HFSC are not in the existing NS-2 code base. Does anyone have pointers to an implementation of either of these queuing disciplines? Thanks
Re: [ns] Ping over LAN missed packets
Hi,
I think there is bug with the Ping Agent. If we simulate Ping Agent with
only 3 nodes, it works fine but if we increase the number of nodes to more
than 3, there are packets lost. I am able to provide a fix and described
below. Please let me know if it helped you out.
In the recv() function in ping.cc, declare the following two variables in
the first two lines.
nsaddr_t source;
nsaddr_t destination;
Then after hdrip is assigned values (hdr_ip* hdrip = hdr_ip::access(pkt);),
add the following two lines.
source = hdrip-src_.addr_;
destination = hdrip-dst_.addr;
Now go to the part of the routine where the following statement is declared:
if (hdr-ret == 2)
Under this part of the if statement, after the statement: hdr_ping* hdrret
= hdr_ping::access(pktret);
add the following lines of code:
hdrip = hdr_ip::access(pktret);
hdrip-src_.addr_ = destination;
hdrip-dst_.addr_ = source;
After adding all these lines, build it again and then simulate. Hope it
fixes the problem. Let me know in any case.
Thanks,
- Faisal Siddiqui

As I know, wireless channel is broadcast style. So in your case, I think node 2,3,4 should received the interest and disseminate interest immediately. The sending order depends on their receiving order.

Re: [ns] Ping over LAN missed packets
Hi Faisal,
First, I want to thank you for your quick cooperation.
Second, I still have problems with the ping/LAN even with your
recommendations. I do not know what is happening.
Third, I make an scenario with 4 nodes connected with duplex links, and there
is not lost packets.
Fourth, I am using the last version of ns2 (ns2.29). The statement if
(hdr-ret == 2) has changed to if (hdr-ret == 0), but the rest of the code
is still the same.
Once and again thank you, and If you or anyone else have an idea I would
appreciate.
