Re: [ns] NAM trace file -e option
Hi,
210 bytes is the total size of the packet. This includes the size of
all the headers (RTP/UDP/IP/...) + the size of the payload. You'll
have to use the protocol's access methods to query for the real size
of the payload. However if you're simulating CBR stuff over RTP then
all your calculations would be simplified since the payload size is
likely to be constant through the time (think of an MP3 frame or an
MPEG TS packet, etc.).
Regards,
Ilyes Gouta.

[ns] Getting Error : Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl)
Dear all,
I tried creating a new simple Agent which broadcasts the packets with its
fields set statically. I created a linear static topology just to set if the
broadcast works. The topology is like
01 2
Part of my tcl script is
set p0 [new Agent/Ant]
$node_(0) attach $p0
set p1 [new Agent/Ant]
$node_(1) attach $p1
set p2 [new Agent/Ant]
$node_(1) attach $p2
$ns at 1.0 "$p0 broadcast"
$ns at 1.5 "$p0 broadcast"
$ns at 2.0 "$p1 broadcast"
Now when 0 broadcasts it is correctly received by 1. when 1 broadcasts, it
should be received by both 0 and 2 since both are within 1's tranmission
range(???). Now i get the following output :
num_nodes is set 3
INITIALIZE THE LIST xListHead
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 550.0
SORTING LISTS ...DONE!
Node 1 received broadcast from 0 with no of neighbors 10
Node 1 received broadcast from 0 with no of neighbors 10
Node 0 received broadcast from 1 with no of neighbors 10
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o74: no target for slot 0
_o74 type: Classifier/Port
content dump:

0 offset
0 shift
2147483647 mask
1 slots
slot 255: _o76 (CMUTrace/Recv)
-- Finished standard no-slot{} default handler --
The problem is node2 is not receiving anything and it is showing some error.
Please help me in fixing this problem. I need this to proceed with my final
year engineering project. Please help me please...

Re: [ns] Compiling NS2.29.2 on FC5
Hi, Yeah, FC5 comes with a brand new GCC compiler (the 4.0.x series). This is the source of all the trouble. I did the same from Tcl/Tk and I was able to get it up and building. However, I got some other issues w/ OTcl/TclCl related to some shell incompatibilities (expression evaluation) and then I gave up since a release is meant to run flawlessly out of the box and it's not up to the users to fix it.

Hello, Could you please tell me which file/code in ns is responsible for processing a cbr packet, and discard it (after writing any traces) as it has reached its destination and does not need to be forwarded again? The code which calls on the cmu-trace for the "agent" tracing of the reception of the packet seems to be the final task before the packet is forwarded (sent to the routing agent) or discarded if it has reached its destination, but I could not locate where this code actually is. Could anyone please guide me? Thanks. Ma Send instant messages to your online friends http://au.messenger.yahoo.com

Re: [ns] Can we change the transmission range of the node during the simulation?
Hi, You can change the nodes transmission range by changing the value of RXThresh_ of Phy/WirelessPhy by doing : Phy/WirelessPhy set RXThresh_ A separate C program is provided at ~ns/indep-utils/propagation/threshold.cc to compute the receiving threshold. You have to compile it, then you can use the executable to compute the threshold as follows: threshold -m [other-options] distance Ex: threshold -m Shadowing -r 0.95 50. Here the propagation model is Shadowing, the communication range is set to 50m, and 0.95 is the rate of correctly received packets. Hope it helps.

[ns] Stumped on this problem
Hi, I have been learning how to use ns and I have run across a couple of problems. The first problem is the NAM editor seg faults when any objects are deleted, even a simple node, on linux, fedora core 4. My second problem has to do with dynamic routing, in one of my simulations there are some agents talking to other agents across the network and on that part of the network there is only one connection. In the simulation I have that single connection go down for a short period of time and this is when all hell breaks loose. All the nodes keep sending the packets to update node information constantly until there are millions of these packets circulating around the network, never disapearing. I am wondering how you can set either a timeout or max # of hops on the packets to keep this happening or is this a bug in NS? Turning off the dynamic routing fixes the problem and the simulation works as expected for that part. If any of you can help me on this problem, it will be appreciated. Thank you, Randy

Re: [ns] How to access c++ variable from tcl
Hi,
You can access this function (recv as you say) via command function.
Command function in your c++ code serves as an interface between tcl
code and c++ code. All you need is adding some peace of code that
controls wihch arguments passed by the tcl interpreter. Like that:
int MyAgent::command(int argc, const char*const* argv) {
if (argc==2)
{
if (strcmp(argv[1],"recv")==0) {
recv();
return (TCL_OK);
}
}
}

Re: [ns] NAM trace file -e option
Hi,
I understand your point. I would really appreciate if you could elaborate
more and direct me to the exact structure location in the code from whre we
compute the packet size for -e option. I tried to look in the code but can't
really pinpoint the structure from which it computes the packet size.
Another thing I noticed was the incorrect hdr_cmn size being reported. I
checked the sizeof (hdr_cmn) and it reported the size as 96 bytes. But if
you go to the hdr_cmn structure, you will find that it's size should be much
bigger than 96 bytes because of obvious reasons.
Any comments are appreciated.
Thanks,
