[ns] no-slot{} default handler
Hello all,
I have encountered again a problem in NS2 which I have no clue about.
i receive this error:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o188: no target for slot -1
_o188 type: Classifier/Hash/Dest
content dump:

1 slots
slot 8: _o2455 (classifire/Port)
-1 default
-- Finished standard no-slot{} default handler --
nobody have any idea?
looking forward to hearing from you

[ns] SCTP-aware applications in NS
Hi ns-users, I´m doing some simulations with SCTP in NS-2 and i want to use a SCTP-aware application using Application/SctpAppl1 instead FTP or other legacy-ns applications. I have some questions about how I can implement this. Can anybody send me an example, please? I appreciate some help. Thanks in advance Elisabete Reis

[ns] GPSR compile and simulation
Dear all
I want to use GPSR protocol in ns2.27. I have done all this steps that
I have found in internet
1- Create a directory "gpsr" with gpsr.cc and gpsr.h
in it.
2- Declare gpsr packets in common/packet.h, adding
PT_GPSR and in packet.h with name_[PT_GPSR] = "GPSR"
3- The tracing support doesn't need to be implemented
right know.
4- In tcl/lib/ns-packet.tcl add "GPSR". Then you'll
have to declare all defaults values of gpsr binded
attributes in tcl/lib/ns-default.tcl. To do it easily,
have a look at the end of the ns-default.tcl file
originally used bu gpsr in ns2.1b6. You'll get
everything you need. It should look like Agent/GPSR
set . Copy paste it to your ns-default.tcl file.
5- You have to add procedures to create gpsr nodes in
tcl/lib/ns-lib.tcl. You must add in
Simulator instproc create-wireless-node args{
}
the following:
GPSR {
set ragent [$self create-gpsr-agent $node]
}
Then, add the pocedure
Simulator instproc create-protoname create-gpsr-agent
{node} {
set ragent [ne Agent/GPSR]
$ragent node $node
$self at 0.0 "$ragent start"
return $ragent
}
6- Finally, update the makefile to compile everything
by adding the folowin line
gpsr/gpsr.o\
However, when I try to compile gpsr.h, I get many errors.
Does anybody have the same problems??How can I solucionate it?
Thanks to everybody,
MIKEL

[ns] found the right version of tclsh
When configured, ns found the right version of tclsh in /home/azhar/ns2install/bin/tclsh8.4 but it doesn't seem to be there anymore, so ns will fall back on running the first tclsh in your path. The wrong version of tclsh may break the test suites. Reconfigure and rebuild ns if this is a problem. actually , when i search the /home/azhar/ns2install/bin/tclsh8.4 i remember that 'ns2install' was in my old installation directory. is it mean i need to run back my installation ./install again? or i need to make a littel changes -- AZHAR MOHD ARIS Master Candidate Of Distributed Computing University Putra of Malaysia
[ns] invalid command name "Application/MmApp" w/ns tutorial
Hello ns-users, I am attempting to run the example code here (http://nile.wpi.edu/NS/ - just click on 'Add new application and agent') and I have downloaded it and made the appropriate changes. When I run 'ns ex-mm-app.tcl' I get this error: ns: [code omitted because of length] : invalid command name "Application/MmApp" while executing "Application/MmApp set rate0_ 0.3mb" Has anyone else had and solved this error? Thanks for any help. -- Sincerely, Candace Phelps
[ns] The reception of the packets at the destination
Dear all,
I was using UM-OLSR (0.88, NS2.29) to simulate the network and trying to do
some operation at the destination. Normally, we add this kind of code in the
recv() method for reception:
*recv() {*
.
**
* if (ch->direction() == hdr_cmn::UP &&
((u_int32_t)ih->daddr() == IP_BROADCAST || ih->daddr() == ra_addr())) {
//do sth. ...*
* dmux_->recv(p, 0);
return;
}*
**
*}*
**
But it seems that when the NS2 is trying to receive the packet at the
destination, the recv() method is never called, and the packet is delivered
directly from the MAC layer to AGT layer. And from the trace file I got:
r -t 9.799191277 -Hs 1 -Hd 1 -Ni 1 -Nl MAC -Nw --- --Ii 622 -Iv 29 -Pn cbr
-Pi 0 -Pf 4 -Po 3//the mac layer of the destination get the packet
r -t 9.799216277 -Hs 1 -Hd 1 -Ni 1 -Nl AGT -Nw --- --Ii 622 -Iv 29 -Pn cbr
-Pi 0 -Pf 4 -Po 3 //and pass it to the AGT layer, without passing the
RTR layer
The situation is the same with DSDV and AODV protocol in NS2.
But in DSR, we have:
r -t 9.801548775 -Hs 1 -Hd 1 -Ni 1 -Nl MAC -Nw --- - -Ii 0 -Iv 30 -Pn cbr
-Pi 0 -Pf 3 -Po 3
r -t 9.801573775 -Hs 1 -Hd 1 -Ni 1 -Nl RTR -Nw --- --Ii 0 -Iv 30 -Pn cbr
-Pi 0 -Pf 3 -Po 3 //here the packet is in RTR layer!!! This is what I
want
r -t 9.801573775 -Hs 1 -Hd 1 -Ni 1 -Nl AGT -Nw --- - -Ii 0 -Iv 30 -Pn cbr
-Pi 0 -Pf 3 -Po 3
I try to analyse the differece in the code between the protocols, but have
no idea about this problem. Is there anyone know about it? It will really
save my ass
Thank you in advance.
Best regards,
J. Yi
[ns] need help to evaluate performance of wire less mesh network routing protocols
I'm confused how to proceed. I was tried to do evaluation of multichannel and multi interface support for wireless mesh, I downloaded the ns-2.29_multichan and it didn't workk. And later, I started to evaluate performance of mesh routing protools and they are not fully supported in ns2.(only AODV,TORA,DSR and DSDV which are adhoc routing) can any body help me? - Shape Yahoo! in your own image.

[ns] someone working with the ns2hcca patch ?
Hello all If someone is working with the ns2hcca patch from http://info.iet.unipi.it/~cng/ns2hcca, someone could tell or explain me why in the example included in the directory tcl/ex/hcca (example.tcl) the delays in DCF are smaller than the delays in HCCA. this should not be this way because the delays in hcca should be smaller than the delays in DCF because HCCA guarantees quality of service (QoS) y DCF don't guarantees QoS I appreciate your time and your help. And I apologize for any inconvenience that this cause. Thank you for everything.

That means, set it to (for example) to 2dBi for the first 50 nodes and 8dBi for the next 50. Use the propagation.cc utility to calculate the exact parameters (search the list for details). But be aware, the transmission range depends on both, the sender and the receiver. That means, if you have two kinds of nodes (A and B) you get 3 different combinations and hence communication ranges (e.g. A->A: 250m, A->B: 400m, B->B: 500m). Hope this helps, Daniel. -- Dr.-Ing.
