[ns] Display in NAM
Dear All,
I am working on Online Video Streaming, and i have to build a topology using
gt-itm topology generator.
Following is the program, but in output i m not getting any display on
Network animator (NAM).
can anybody suggest me the correction in program?
set ns [new Simulator]
set nf [open out.nam w]
$ns namtrace-all $nf
proc finish {} {
global ns nf
$ns flush-trace
close $nf
exec nam out.nam
exit 0
}

[ns] Changing behaviour of node.
Im kind of new to ns2, i need help in changing the default working of the node. I dont know how to apply the changes to the code. COnsider 3 nodes: A,B and C. C is like a router. A sends packet to B through C and B sends to A via C. In normal operation, when C gets the packets simultaneously, it sends one by one to A and after that to B (not at a time). But i want C to send both the packets simultaneously to A and B. Like this in the receiver end, A will XOR the received packets with its own packet so that it receives its required packet. B also does the same. Can u please tell me how to implement this?...and wat changes are to be made and where?... I would really appreciate your help! -- View this message in context: http://old.nabble.com/Changing-behaviour-of-node.-tp30800274p30800274.html Sent from the ns-users mailing list archive at Nabble.com.

[ns] Adding a new command
Hi,
Since there is no node-down command defined for 802_11 like the one in
802_15_4 I m trying to add one to 802_11. As you may know there is a
command method defined like this in mac-802_11.cc
Mac802_11::command(int argc, const char*const* argv)
When I add my node_down command in that method I get a tcl error.
When I check I saw that each time when there is no such command found
command method of a more general class is called.
For instance when there is no such command in 802_11 then mac command
Mac::command(argc, argv);
is called. If not found again then
BiConnector::command(argc, argv);
command is called from mac class. I tried adding my command also in
Agent.cc and Object.cc commands but id didnt work either. I got
following tcl error.. Can you see what Im missing?
ns: _o1279 node-down11:
(_o1279 cmd line 1)
invoked from within
_o1279 cmd node-down11
invoked from within
catch $self cmd $args ret
invoked from within
if [catch $self cmd $args ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error error when calling class $cls: $args $...
(procedure _o1279 line 2)
(SplitObject unknown line 2)
invoked from within
_o1279 node-down11
Re: [ns] Adding a new command
Hi,
Please try to access the mac command() by writing the following commands in
your tcl script:
setMub_Mac_(0) [$node_(0) set mac_(0)]
$ns_ at 0.0 $Mub_Mac_(0) *myfunction* 1;
Define *myfunction* in the Command of Mac802_11...Once the handler is in
myfunction of Command of Mac801_11, then there you can call the function
node-down...
Hope it helps

Re: [ns] Packets in link's Queue
HI, NS2 implements buffering in link, not in node. This is to model the link with large bandwidth-delay product. For example, consider a link with 100 Mbps link and 1 s propagation delay, and packets whose size is 1 Mbits. Then this link can stores upto 100 packets at any instance.

Re: [ns] Urgent Help Needed with running AODV on NS-2.34
Hi Anoop, As you said you have already generated the traffic file and scenario file from the internal script provided in NS-2 installation than in your tcl script there is no use to mention the below lines, you can simply scrap these lines from your TCL script: # Provide initial location of mobilenodes #$node_(0) set X_ 10.0 #$node_(0) set Y_ 15.0 $node_(0) set Z_ 0.0 #$node_(1) set X_ 20.0 #$node_(1) set Y_ 25.0 #$node_(1) set Z_ 0.0 #$node_(2) set X_ 200.0 #$node_(2) set Y_ 225.0 #$node_(2) set Z_ 0.0 # Generation of movements #$ns at 10.0 $node_(0) setdest 10.0 5.0 3.0 #$ns at 15.0 $node_(1) setdest 45.0 14.0 5.0 #$ns at 110.0 $node_(0) setdest 48.0 5.0 5.0 # Set a TCP connection between node_(0) and node_(1) #set tcp [new Agent/TCP/Newreno] #$tcp set class_ 2 #set sink [new Agent/TCPSink] #$ns attach-agent $node_(0) $tcp #$ns attach-agent $node_(1) $sink #$ns connect $tcp $sink #set ftp [new Application/FTP] #$ftp attach-agent $tcp #$ns at 10.0 $ftp start Because if you see the traffic generation file and scenario file than you will find alll these details are already present in those two file. Also apart from this, the error warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl is just a warning and it wil not affect your simulation and results in any way. Though its a good practice to use the new version of specifying the channel in TCL file and that new method of specifying the channel is provided in wireless-mitf.tcl a already provided TCL file with NS2 installation. Also the tool provided in the below link is not very handy (thats what i felt when i used it) as the tcl file generated by that tool for 50 nodes will be a huge file and if you get any error than it will be little complicated for you to debug it as you are new user. Just for your understanding, refer to the 2 below link which i am providing you. Also after some time i will provide you my simulation for AODV and DSR for 50 nodes along with the awk script to play with the trace files. But before that refer to the below links and try to understand their tcl files and their scripts. http://140.116.72.80/~smallko/ns2/adhoc_routing.htm http://users.crhc.illinois.edu/thkim/ece439/ns2_assignment2.htm Also remember, you might get some error while running the TCL files given in these 2 links which if you observer closely you can rectify by urself or else you can drop me a mail if you face any problem.
