[ns] how to detemine channel used by 802.11 nodes
Hi All, I was just wondering as to how we can know which channel is 802.11 node is using. Is it possible to find it from somewhere regarding the channel used information. 802.11b uses three channels so which channel a specific node is using, how can we get to know that ? Please help me at your earliest. I am pressed in time. Thanks in advance. Manish Ph.Dc, Wireless comm. and networking - Do you Yahoo!? Get on board. You're invited to try the new Yahoo! Mail Beta.

[ns] enabling Network/Pcap/Live on Linux
I am working on testing some routing protocols that have
been implemented by my team as Linux kernel modules.
I would like to use NS to test these modules but when
I try to use [new Network/Pcap/Live] I get errors:

Questions:
1. Is Network/Pcap/Live only support on BSD? Some of the google
searches stated as such but were several years old.
2. Or am I missing a tcl support file that is needed?
Bottom line: What do I need to do to figure out how to enable Live
mode and get it to run?

[ns] datarate from tracefile
i) can someone please tell me how to measure the datarate from the trace file. I am using ns2.1b7a, and i have set the mac trace on, and the packet size is 1000bytes, and i set the dataRate at 11Mb in the tcl file. i want to see if the datarate is actually working or not. I searched the archive, theres a post abt time of transmission of data frame, but i didnt get it ... if someone could help me please. ii) To set individual data cbr datarate of nodes to 11Mbps, i set packet size =1000bytes, interval_=.00072 and rate_=11000Kb.. am i doing this right ? thanks in advance, any input would be really appriciated, Roy
[ns] DCCP problem with wired and wireless nodes
Hi, I have ns-2.28 and I have installed Eugen Dedu's DCCP patch for that version from http://lifc.univ-fcomte.fr/~dedu/ns2/. Problem is that DCCP's connection initialisition doesn't work, because the receiving node is in CLOSED-state and it refuces all packets including this DCCP_REQUEST-packet. The sample scenario by Eugen Dedu works fine (dccp-wireless.tcl), but with my wired/wireless -scenario DCCP code fails. My scenario is as follows: Correspondant node <---> Router <---> Base station <---> Mobile node Traffic direction is from Correspondant node to Mobile node. I put some printfs to dccp.cc and I discovered that Mobile node is in CLOSED-state in the beginning of the scenario, but it should be in LISTEN-state. I tried to modify the dccp.cc, but I didn't get that working as DCCP should work. Is it a bug or is there options that I haven't thought? Where in the code are node's options set? Hopefully someone can help me -- | Simo Lintunen| | [EMAIL PROTECTED] |
Re: [ns] OTCL-Linkage
Hello Prashant Batra, actually I thought about a solution with global variables, but I want to use my new class the same way the AODV protocol is used just with some extensions and without affecting AODV. That's why I think it's best to go on looking for a solution accessing objects created in my tcl script. Thank you anyway. jana -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

Re: [ns] Problem with .o files
Hi, When you run ./configure, your makefile gets altered. That's why your line 'disappeard'! And as a result, file.o was not created, hence the 'invalid command' error. (you only need to run ./configure if you're compiling for the very first time) So, once you add the tcp/file.o \line, just run make. If it's successfull, it'll create file.o (you can check this) Then you shouldn't get the error when running your tcl script. Hope this helps!

Re: [ns] OTCL-Linkage
Hi Jana,
Interesting Problem !! But, unfortunately I am also new to NS-2, so I
can't answer your question in the way you expected, but I can propose an
alternate solution, purely on the C++ platform.
If you need just one instance of the ContextAgent object, you can create
a Global variable or a member variable in AODV class, where you can
register your pointer to the newly created ContextAgent Object. Now, in
your AODV code when you need to access the member variables of the
ContextAgent object, you simply dereference this pointer and access the
variables. Obviously, you can acess them, as AODV has been declared as a
Friend Class.
Alternately, if you need more than one instances of the ContextAgent
class, you can create a Global or a member variable in AODV class, of
the type HashTable or something simmilar, in which you can register an
identifier and the pointer to the ContextAgent object, everytime you
create it. Whenever you need to access the variables of the ContextAgent
class, you will also have to pass along this identifier, so as to access
the appropriate object. This identifier could be the node name or
anything you please.
This could be a way out of your situation, even though it will be much
better and smarter, if you are able to find the way of accessing objects
created in your TCL script, in the C++ code !!
Hope this helps.
Regards,
Prashant Batra

Re: [ns] OTCL-Linkage
Hi Jana,
I can't see the solution straight away and without looking at it longer
I can't tell you.
Your solution looks ok but I am concerned about your use of friend. Does
it actually create an AODV agent?
I'd suggest using gdb with breakpoints to work out what is going on.

Re: [ns] installation problems with otcl-1.11
Hi, Well you have to do what the message says. Clearly, your X11 Header Files are missing. You will have to pick up your FC5 CD/DVD, and install the Header Files. If you run the Package Installer or Update Manager, you will have to go into the Development / Library section of packages, find X11 related packages / headers and install them. Once the headers are installed, the installation should (hopefully) run smoothly !! Good Luck !!

Re: [ns] Problem with .o files
Hi, Your observations are expected!! The only thing that's going wrong in your case is that you do './configure' over and over again !! When you run './configure', it regenerates a new Makefile, which overwrites the Makefile that you modified. Thus, your changes vanish. So, after you modify the Makefile, please do not run the 'configure' file again. Just do 'make' and 'make install' Regards, Prashant Batra Aleksandar Smolovic wrote: > Hi all, > > I have file.cc and file.h and I put that in for example ~/tcp/file.cc and > ~/tcp/file.h. > > Now I make neccesary modifications and among other things in OBJ_CC section > on "Makefile" I have put this > . > tcp/file.o \ > .. > > When I do "./configure" and "make" and "make install" I do not have "file.o" > under path where I put file.cc and file.h. > > In futher, I open "Makefile" after congifure,make and make install procedure > and there is no line I put - the line I mentioned above tcp/file.o \ > > How can disapear a coplete line from "Makefile" ? > > Am I missing something here? > > When I try to start ns on prompt I have something like this: > > machine:/mypath/# ns > ns: > [code omitted because of length] > : invalid command name "Agent/TCP/WestwoodNR" > while executing > "Agent/TCP/WestwoodNR set current_bwe_ 0" > machine:/mypath/# ns > > > Thank you. > >
[ns] OTCL-Linkage
Hello P.
actually I need only the values of the bind variables in the AODV agent. The
binding itsself works - I've tested it.
What I want is to use the value of, let's say, rq_context in the function
AODV::sendRequest(). This variable has the value of 0, it gets it in the
simulation script:
set context1 [new Agent/Context]
$ns_ attach-agent $node_(1) $context1
$context1 set rq_cxt_otcl 0
$context1 set rt_cxt_otcl 5
But I don't know how to call on the current instance of my ContextAgent out of
the function sendRequest()to be able to us the value of rq_context???
// call in AODV-function
void
AODV::sendRequest(nsaddr_t dst) {
...
ContextAgentObject = ;
rq->rq_cxt = ContextAgentObject->rq_context; //value of rq_context
should be 0
...
}
