[ns] RE : Scenario File
Hi, You must generate two files. One traffic file and one mobility file and call them in a tcl script that you can find examples in the folder ns-2.x/tcl/ex (for example wireless.tcl). Do like this: 1. go in the folder ../ns-2.x/indep-utils/cmu-scen-gen and type ns cbrgen.tcl -type cbr -nn 50 -seed 1.0 -nc 20 -rate 10.0 traffic-file-name. (20 = source nodes) 2. go in the folder ../ns-2.x/indep-utils/cmu-scen-gen/setdest and type ./setdest -v 1 -n 50 -M 20 -t 800 -x 1000 -y 1000 mobility-file-name. (20 = velocity It is supposed here that the minimum velocity is 0 and the max 20). The mobility model is Random Waypoint. After that use the two files in your script tcl like in the example Wireless.tcl. I hope I didn't make mistake on the parameters of cbrgen and setdest. You can verify them in the programs cbrgen.tcl and setdest.cc in their folder. Molo.

[ns] how to get handles (pointers) to multiple agents from an application
Hi I am working to develop this application that needs to talk to other applications. They all use tcp as their transport agent. When one node can talk to two other nodes, then it has two agents attached to it. Before settingup the ip addresses it has to select the agent (ie. agent_ -sendmsg()) to send its message. The message can go out either link of the node. How can I get the pointer to the agent I want to send the packet. All this is being done in C++. I would really appreciate ur help.

[ns] Attaching problem
Hello, I'm Patrick. Can someone help with TCP problem? I'm trying to run
following tcl code: or {set i 1} {$i=$NetNb1} { incr i } { for {set
j 1} {$j=$NumFlows} { incr j } { set tcpsrc($i,$j) [new
Agent/TCP/Newreno] set tcp_snk($i,$j) [new
Agent/TCPSink/DelAck] $tcpsrc($i,$j) set packetsize_ 1000
$ns attach-agent $N1($i) tcpsrc($i,$j) $ns
attach-agent $Server tcp_snk($i,$j) $ns connect $tcpsrc($i,$j)
$tcp_snk($i,$j) set ftp($i,$j) [$tcpsrc($i,$j) attach-source
FTP] } }a so on, nothing difficult. But instead proper function I get
the error output like this: invalid command name tcpsrc(1,1) while
executing $agent set node_ $self (procedure _o58 line 4) (Node
attach line 4) invoked from within $node attach $agent (procedure
_o3 line 2) (Simulator attach-agent line 2) invoked from within $ns !
attach-agent $N1($i) tcpsrc($i,$j) (for body line 8)
invoked from within for {set i 1} {$i=$NetNb1} { incr i } { for {set
j 1} {$j=$NumFlows} { incr j } { set tcpsrc($i,$j) [new
Agent/TCP/Newreno] # setting tcpsink w... (file
mypareto.tcl line 54) This part of code is from 'NS2 for beginners'
(Chapter 4 - TCP/IP), but it doesn't work. However, this code seems to be all
right to me, I don't understand, why ns don't want to attach agent, and what's
the problem concerned in $agent set node_ $self. When I was trying similar
code as one dimensional array (only $i) on version ns2-29 the error was the
same... so there is probably some error in that part of code, but as I
mentioned, I don't see, and was trying to do little changes to code, but
without positive effect. Any idea? Thank You for any help friends...
[ns] [ns2]address classifier problem
Hi: The ns2 manual says that addressclassifier is the default classifier for unicast routing (page 45) in wired network. A node in wired network is default a unicast routing node. When I am using gdb to debug my program, I find that the truth is not the same as what the manual says. I find that dstHashclassifier is the default classifier. why ? thanks . I want to control the fowarding of each packet a node received, So I modify the addressclassifer class, the manual same it is the entry of a unicast node, and will receive every packet flow over the node, including ones from uplayer or down layer. great thanks yang - 雅虎免费邮箱-3.5G容量，20M附件
[ns] Printing value of Scheduler::instance().clock()
I'm using NS-2 version 2.29 on a Fedora Linux PC. I'm using a MAC
protocol, and I want to find the average delay time. I heard that I need
to do that with changes to the C++ code, rather than a tcl script.
I want to write the enqueue packet time to file1, and dequeue packet time
to file2. Then, with a perl script, subtract the times in file1 from file2
to get the delay times. But I'm not sure where to make the changes to the
C++ code (I tried modifying queue.cc; See below), and I'm having a problem
using Scheduler::instance().clock() when writing the time to a file
because I get arbitrarily large numbers and negative numbers.
Any suggestions would be appreciated.
Thanks,
Mark
