[ns] Getting help about simulating FDMA like Mac protocols in ns-2
Dear All. I want to simulate multi-channel Mac protocol in the NS-2 (simulating FDMA like Mac protocol). But I haven't any information about simulating this protocol. How I can create multiple channel for a node. How I can divide wireless bandwidth (frequency) into the multiple channel (frequency division). How I can switching within channels. How I can read the sate of these channels. And etc. Best regards. Ali Chodari Khosrowshahi.
Re: [ns] Location aware protocols in NS
Hi,
To have current position of a node at agent level, you can do :
MobileNode* mnode_;
double x = 0.0,y = 0.0,z = 0.0;
mnode_-getLoc(x, y, z);
You should have mnode_ referencing to a node. For example, in my case I pass
the node address to my agent in the tcl script and for this reason i defined
a new node command in the Command( ) method of the agent like this :
if(strcmp(argv[1], node) == 0) {
mnode_ = (MobileNode*) TclObject::lookup(argv[2]);
if(mnode_ == 0)
return TCL_ERROR;
return TCL_OK;
}
then in my tcl script I create a node node_1 and my agent , then I do
$my_agent node $node_1
Hope this helps.
Bye.

Hi,
I am using ns-2.29 and currently implementating a new protocol which
depends on the location information of the nodes. How can I get the
location
of the attached node from the agent code. Even if I keep the location
information in the agent information ( say by keeping it in routing
table),
how to set the corresponding entries. I have made the variables accessible
to the tcl script using bind function but how can I access the routing
agent
corresponding to a particular node? It would be better for me if I get the
x-cordinates and y-coordinates of the grid topology assigned to the node
from the routing agent.

[ns] R: regarding promiscuous mode
Krithiga, answers are inline. Regards, Marco Fiore Messaggio originale Da: [EMAIL PROTECTED] Data: 12-mar-2006 1.24 PM A: ns-users@ISI.EDU, [EMAIL PROTECTED], aodvimpl-public- [EMAIL PROTECTED] Ogg: [ns] regarding promiscuous mode hi all, i am doing proj in mobile adhoc networks. i need to know some clarifications regarding mobile adhoc networks. 1. we need to make use of promiscuous mode for our proj. (i.e) a node need to overhear the other transmissions that are happening in its transmission range.. is it already implemented in NS2? If so, kindly let me know the inbuilt function that can be used for overhearing. Otherwise, how this overhearing concept can be implemented in NS2? There's no promiscuous mode implementation in ns-2. However, you can easily add such feature in 802.11. In the file mac/mac-802_11.cc, look for the recv_timer() function, look for the Address Filtering section: there you can decide to pass the frame to the upper LL agent, instead of discarding it. 2. how can we determine the 2-hop neighbours of the node and maintain the list of the same?? Two ways: the easy, bad one is to make it via tcl (e.g. at each time step, compute all inter-node distances and comunicate to each node the list of neighbors), the more complex, good one is to do that implementing in C++ some layer-3 mechanism which propagates the information on neighbor nodes using actual packets (many examples of that in literature). This second solution is preferable since it is more realistic (in the first case you have a no-error, no-cost information exchange!). I think you could loo for some existing C++ implementation and start your changes from there...
Re: [ns] SIP patch
Hi
This error means that NS-2 does not know anything at all about the
Application/Traffic/SipUdp class. Indeed, I have looked through the code, there
is no line that registers such a class. Buggy patch :-(
However, as I have understood from the implementation, the Agent/UDP/UDPSIP is
responsible for carrying SIP messages, while Application/Traffic/SipUdp is just
some class that generates traffic. Basically, you can attach any traffic type
you need since the main functionaly is implemented in Agent/UDP/UDPSIP.
So, you can take a test script and use, for instance, CBR traffic type instead
of Application/Traffic/SipUdp. Ideally, it would be nice if some of the
developers clarify this problem.

Hi
I have tried to apply this patch, there are indeed several problems that you
can solve easily and contribute a new patch for ns-2.29.
Failed hunks in common/packet.h:
Basically, everything you need in common/packet.h is PT_SIP (hunk #1m it
succeeded) and name_[PT_SIP] = sip; in class p_info (hunk #2, it has
failed). Remaining hunks are not necessary, they are just some garbage.
Failed hunks in Makefile.in:
Many hunks in Makefile.in has failed, but some of them are also garbage.
Just add a new line to the list of objects to compile
sip/sip_udp.o apps/udp_sip \
Failed hunks in trace/trace.cc:
It seems that the purpose of those modifications! is just to put more
information about each packet into the trace file. Nice, but test scripts
should run without those changes, unless they analyse the trace at the end
of simulation. Just remove hunks that relate to the trace.cc file
So, you can take the original patch, remove all the hunks that relate to
the common/packet.h, Makefile.in, and trace/trace.cc files, then make
manually changes in the common/packet.h and Makefile.in files as I have
explained above, try to compile and run. If something goes wrong, you can
contact me. Unfortunately, I have no time at the moment to do it :-(
Also, you may be interested in the SIP implementation that is in the
attachement. I have no idea whether it is a completely different
implementation or just an older version of SIP you are trying to install in
NS-2.29.
Good luck !

Re: [ns] Help: Setdest Command
one thing you can do is to delete any (object files) .o files from setdest directory and run make again. this will definitly generate the binary for you. Hi, I would like to ask regarding setdest command. In the tutorial it says that: In order to compile the revised setdest.cc do the following: 1. Go to ns directory and run configure (you probably have done that already while building ns). This creates a makefile for setdest. 2.Go to indep-utils/cmu-scen-gen/setdest. Run make , which first creates a stand-alone object file for ~ns/rng.cc (the stand-alone version doesnot use Tclcl libs) and then creates the executable setdest. 3. Run setdest with arguments as shown below: So, I have do the first command as below: [EMAIL PROTECTED] ns]# configure then the error would be: bash: configure: command not found When I run the second command: [EMAIL PROTECTED] setdest]# make then the error would be: make: Nothing to be done for 'all When I run the third command: ./setdest -n 50 -p 0 -s 20.0 -t 100 -x 500 -y 500 scen-50-test then the error would be: bash: ./setdest: No such file or directory File setdest.cc is in setdest folder. Inside the folder there is also Makefile, Makefile.in rng.o file others. I did not sure whether for command 1 2, that is the correct way to do so. I am using ns 2.26. I use command ./ns file_name to run tcl script. Hope anybody can help me. Thank you regards, norlida - Brings words and photos together (easily) with PhotoMail - it's free and works with Yahoo! Mail.
[ns] regarding ns2 debugging
Hi all, I need some clarification regarding debugging in ns2... I have used 'gdb' in the past to debug c/c++ programs.I tried to use it for ns2 debugging also.It works but I am confused as I don't know whether gdb alone can do all the debugging in ns2, as ns2 is built using both c++ and tcl.If tcl in ns2 is used only for configuration purposes, than gdb alone should be sufficient.Otherwise have to use tcl debugger also. Please clarify! And how do I debug simultaneously in c++ and tcl? Thanks!

Its not a bug, your path to the script files needs to be modified, make

[ns] Capture Bug in ns-2
Let's say we have S1 sending to R1 and S2 sending to R2. S1 and S2 are outside of each other's carrier sense (CS) range. R1 and R2 are obviously both within the receive (RX) range of S1 and S2, respectively. R1 is within the CS range for S2 (but outside S2's RX range). R2 is outside S1's CS range. Note the asymmetry of the topology means that R1 will carrier sense S2's transmissions, but R2 will not carrier sense S1's transmissions. 1. S1 starts sending an RTS to R1. 2. Before S1's RTS finishes, S2 starts sending an RTS to R2. In ns-2, this causes the capture function in mac-802_11.cc to be called at node R1. The effect is that R1 will set its NAV for EIFS plus the txtime of S2's RTS. 3. When S1's RTS finishes, R1 cannot send a CTS since its NAV was just set in the capture function. 4. Every time that S1 trys to retransmit an RTS during S2's data transmission, R1 is unable to reply with a CTS. This can cause S1's backoff window to get relativley large. 5. When S2 finishes sending and tries to transmit another packet, there's a relatively decent chance that it will send its RTS and start sending the data packet before S1 can send an RTS (S2's backoff is relatively small and S1's is relatively large). This causes Step 4 to repeat and S1 may reach its RTS retry threshold and consider the link dead. In a correct implementation, I think that R1 should be able to send a CTS in response to S1's first RTS and S1's transmission can proceed in parallel with S2's transmission. It seems this was mentioned over two years ago on the list, but the bug still exists in the most recent CVS code: http://mailman.isi.edu/pipermail/ns-users/2003-December/038043.html -Matt
