[ns] Queue Monitoring problem - urgent help needed!
Hello to everybody who attends this list,
I am a new ns2 user so may be this question will look simple to many of you:
My objective is to monitor the queue length of the bottleneck link between
router and server which i limited as follows:
$ns queue-limit $n_router $n_server $buffer_size
The buffer size is an integer number (in my case it was 362). Then i defined
the instance of the queue-monitoring object as follows:
set qmon [$ns monitor-queue $n_router $n_server ]
and i zeroed the fields i need to monitor at the start of simulation like
this:
$ns at $sim_trace_start $qmon set pdepartures_ 0 ; \
$qmon set parrivals_ 0 ; \
$qmon set pdrops_ 0 ; \
$qmon set pkts_ 0;
Then i tried to print the intantaneous size of the queue by approaching
fields pkts_, and also reading the feild pdrops_, by printing them into the
file,
in a for-loop defined as follows:
for {set t $sim_trace_start} {$t = $sim_end} {set t [expr $t+$time_slice]}
{
.
...
set log2 set cur_arrivals \[$qmon set parrivals_\] ; \
set cur_departures \[$qmon set pdepartures_\] ; \
set cur_drops \[$qmon set pdrops_\] ; \
set cur_pack \[$qmon set pkts_\] ; \
set cur_queue \[expr
\$cur_arrivals-\$cur_departures-\$cur_drops\] ; \
set cur_bpercentage \[expr \$cur_pack*100.0/\$buffer_size\]
; \
puts $qfile \$t \t \$cur_queue \t \$cur_arrivals \t
\$cur_departures \t \$cur_drops \t \$cur_pack \t \$cur_bpercentage \;
$ns at $t $log2
}
However - the pdrops_ is always 0 and the queue length exceeds the limit!
i.e. the pkts_ is more then the limit i defined (=362) and constantly grows!
Why?? PLease someone help me in this obstacle the script is attached, thank
you for your time everybody,

[ns] How to speed up ns-2 simulations
Hi all, I am facing the problem of speeding up ns-2 simulations. I have my own agent and I do simulation on wireless networks with up to 600 nodes. I don't use any routing agent nor I use traffic generators. Assuming that my agent is internally well optimized, I tried to reduce the number of things that ns-2 does in order to avoid unnecessary computation. The first thing was to I avoid the use of GOD. Second, I disabled all the tracing from my Tcl script. Unfortunately I could not disable the creation of the trace file, i.e., I could not get rid of the following lines: set tracefd [open wireless-out.tr w] $ns_ trace-all $tracefd without getting an error. I would like to know 1) if I can totally disable any internal tracing 2) if there are other things that I can disable to make ns-2 run faster either in the C part of the simulator or though Tcl script. Thank you in advance, Regards Michele Battelli

[ns] memory full due to large simulations
hieee, the problem i'm facing is not directly related to NS-2 but its caused b'coz of it so i'm posting it (coz someone else might hav faced it earlier. i ran about 10 simulations in NS-2 and haved the .tr file with different names. while doing so i didn't realize that the size of files was huge enough for my OS to handle. so after some time it stopped responding. i restarted the computer but linux is not working at all. after doing the initial test and allocating spaces etc ( which it performs at linux startup) it shows a blank screen. i have a dual boot OS, and the other one is windows 2000, and it is working fine. i saw that the space i allocated for linux partitions is almost full only few MBs is left. if someone has any idea how i can get the linux start working again plz do let me knowcoz i hav important data which i can't compromise.

[ns] how to add reputation to a neighbor
Hi, I am new to NS and have no experience with tcl. I am trying to make some changes. It works as follows: 1. For each node, there is a reputation table which associate a reputation value for each of its neighbors. I can add a variable int reputation to the structure neighbor_list_node in node.h and initiate reputation using addNeighbor in node.cc. 2. When a node A forwards a message, its neighbors update their reputation table, increase A's reputation by f. Otherwise, neighbors decrease A's reputation by d. 3. When A's reputation drops below a threshold t, all neighbors delete routes containing A. How can I implement this? I am using DSR as routing protocol. Thanks a lot for any ideas and suggestions!

Re: [ns] wireless scripts
Ravi, the files with an extension .tr are not executable/runable files... they are trace files that log simulation activities... you can use any text editor to read its contents.. plus you can script a bash/awk/etc... to make use of the information within this log (e.g. received/transmitted ratio, delays, No. dropped packets, etc...)

[ns] Doubt in AODV protocol and NRTE error
Hi all, I am simulating AODV protocol on NS2. In the trace file I found a line like D 166.721982758 _4_ RTR NRTE 3267 cbr 532 [0 0 0 0] --- [4:1 6:0 30 0] [16] 0 0 i.e a cbr packet is sent at node 4 is dropped at 166.721982758 due to the error NRTE (DROP_RTR_NO_ROUTE). Actually the packet is generated at 146.9.. and route finding mechanism started at that time only... but, the receiver is not sending reply ( I changed the code for not to send the reply). But, from where this message is generated ? and what happened to the cbr packets 0-15 sent by the same node ? I am not able to understand, when NRTE error will be generated and depending on what it will be generated? Is it in anyway depends on rt_req_timeout field of routing table entry ? How and when this kind of error is generated ? Anyone Please help I am in urgent requirement to know about this ... Thanks Regards Anupama A

Re: [ns] CBR over TCP ?
Sounds good. Thank you! Regards, Kai _ From: alaeddine abdallah [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 28, 2006 7:00 AM To: Mohammad Zubair Ahmad; kaibai; Sasan Cc: ns users Subject: Re: [ns] CBR over TCP ? Thank you all for your remarks, I said in the first mail that simulation with CBR traffic and TCP was working but the problem was that the pacet size of CBR was ignored and the rate at the destination was not constant. In fact, the CBR is in the application layer and the TCP is in the transport layer. So the CBR is sending packets (having the CBR packetSize) in a constant rate, than if TCP cannot send packetsin the same rate(depending on Tcp packetSize, etc) , CBR packets will be waiting and that's why we cannot observe a constant bit rate at the destination. So finally, the CBR traffic seems to be a good application to compare UDP and TCP. isn't it ?

Re: [ns] check simulation results of LEACH on ns-2.27

In general, you would normally need the trace-all trace file in order to understand/analyse your simulation. Anyway, you should be able to get rid of it from the script with no error. One of the way I found to speed up simulation is to avoid ns-2 tracing. In order to retrieve the data I need I have a dynamic structure in the agent that stores the data I need. When the agent is done with its work it simply dumps the values in the structure using a simple cout. Unfortunately, removing the line $ns trace-all $tracefile ends up in a error when the nodes are instanced in the tcl file. I can't figure out why.
