[ns] need RSVP/ns example scripts
Dear Ns users, I need some TCL script examples for the RSVP/ns patch from Marc Greis. Due to some prior (and modified) NS nstallations, I cannot use the standard patch to install RSVP/ns, I would therefore be very grateful if you could send me some tcl example files (in a zip or tar.gz file please (but if it is not possible a copy and paste in the body of an e-mail is ok too ;o) )). many thanks!

[ns] how can i run a wireless simulation?
Hello ns users! I have ns-2.29 on Mandriva 2006. I am trying to run the first wireless script from Marc Greis' tutorial. This is what is written in the tutorial: At the end of the simulation run, trace-output file simple.tr is created. As we have turned on the AgentTrace and RouterTrace we see DSDV routing messages and TCP pkts being received and sent by Router and Agent objects in node _0_ and _1_. As i have seen from the first simulations,i am supposed to see the modeled topology in nam.Is this true about wireless simulations?I understood that the file "simple.tr" is the result of running the script,but how can i see the topology,the packets etc in nam? I want to make a comparison between the existing protocols,but i need some xgraph files in order to compare the performance of the protocols(when i say comparison, i mean from the point of view of the overhead, speed, packet drop...).How can i do that? Thank you in advance! Regards, Alexandra - Yahoo! Messenger with Voice. Make PC-to-Phone Calls to the US (and 30+ countries) for 2¢/min or less.

Re: [ns] gprs help!!!!(urgent)
Hi! Maybe this is because your question is written badly and noone knows which code you are talking about? Posting the same question multiple times only annoys people and doesn't help at all. The GPRS code most people know about is by Richa Jain from India. There is a newer Version by Jeisa Olivia Perez(can't remember correct spelling, but if you look at the mailing list archives approx. 12-14 months ago you'll find the announcement) which some people might know about. I do not think anyone knows "the GPRS code contributed by george" without further specification (where is it from? maybe a link?) which is probably why noone is answering. Also, there are just too many people on this list who always post something along the lines of "I have to turn this in tomorrow, please do my work for me" which is why this kind of posting typically gets ignored. Some advice: *) there were several postings of an article "how to ask good questions" in the past on this list. Search them in the archive and read them. *) read the FAQs, etc. Search for your problem in the archives. *) if you are working with ns, start your work EARLY. Do not wait until 2 days before the deadline. *) do not post something that sounds like "I was lazy, I started late, now the deadline is here and I want you to do my work for me". And especially don't post that same mail over and over when people ignore it. It just annoys the hell out of everybody. A much better example of how to write your mail would have been: 1. asking whether anybody knows / works with the code (exact spec which code you are talking about) 2. asking whether they had the same problem (with exact description) and if they could solve it and how. I know this is probably not the answer you were looking for, greetings, Martina seema kukanur schrieb: > > Hi! > i am sending the request to ns mailling list since > from many days, but ur not responding to me. > i am facing the problem while executing the GPRS > code contributed by george in ns-allinone-2.1b9a > version. > then errors which we r getting are > number of nodes set 10. > wrong routing agent. >please give me the solution. > > > > __ > Yahoo!

[ns] Routing protocol OK
Hello NS-users:
I create another identical AODV ad hoc routing protocol in Ns-2 but I
renamed it as ZIGBEE.
I copy all the files in AODV to a new folder call zigbee and renamed all
AODV files (.cc & .h) to zigbee files (.cc & .h). Then I clone the code and
I have changed all the words where the aodv word appears by the zigbee word
(C++ classes, packet headers, variables, TCL bindings,...). I do all
modifications that are needed to integrate a new module in NS2 (tutorial
http://masimum.dif.um.es/nsrt-howto/html/ and Marc Greis s tutorials are
very helpful).
My first error was:
(zigbee/zigbee.o:(.bss+0x10): multiple definition of `hdr_zigbee::offset_'
zigbee/zigbee.o:(.bss+0x10): first defined here
/usr/lib/gcc-lib/sparc-unknown-linux-gnu/3.3.5-20050130/../../
...)
It happened because in 'makefile' there was two lines with zigbee/zigbee.o.
After this error, I have obtained that 'make' does not give me errors. Then
the next step was to simulate a tcl script. I have taken a script that
works with AODV and I have changed val(rp)=AODV for val(rp)=zigbee ($ns_
node-config -adhocRouting $val(rp) ). But when I run the ns, I obtain the
new error:
/home/ns-allinone-2.29/ns-2.29/tcl/ex/wpan $ ns demo1.tcl

set node_($i) [$ns_ node]
$node_($i) random-motion 0 ;# disable random motion
}"
(file "demo1.tcl" line 110)
Then I go to .../tcl/lib/ns-lib.tcl and I verified that I have been mistaken
in the zigbee word. The correct word is ZIGBEE.
Finally I run the ns script and all run ok. I have a new protocol name
ZIGBEE that it is the same that AODV.
The following step is to modify this protocol so that it does exactly what I
want. But this is other history.
I hope that this message helps more people. Thank you.

Re: [ns] Problem running wireless script
Hi Alexandra, It seems that ns is trying to execute "-topoInstance" as a command while it is actually one of the node configuration parameters. I want you to look carefully how you are loading the node configuration parameters. Most likely the end of the line prior to the "-topoInstance $topo \ " is missing \ (which is to indicate the next line is a part of the command. regards >>Hello everybody! >> I am trying to run the first wireless script, >>simple-wireless.tcl and i get a starnge error,ahich i >>can't solve.Here is the output: >> num_nodes is set 2 >> invalid command name "-topoInstance" >> while executing >> "-topoInstance $topo \ " >> (file "simple-wireless1.tcl" line 97) >> >> Anybody knows how this can be solved?Please, i need a >>quick answer.It's quite urgent,i need this for my >>graduation project. >> Regards, Alexandra __ Do You Yahoo!?

[ns] sending packets from objects within agent
Hi, i have implemented a routing agent for ad-hoc routing, but i have a problem: the agent attached to a node has several 'roles', so the agent has a central subclass of agent, and contains several objects which take care of different behaviours. Now i need to send packets from those objects - how should i transmit the Scheduler used in the central agent ? Or should i just transmit target_ ? (or should i use another way to get those packets sent ?) (i use ns-2.29) Masters of ns ;-) , i hope you can help me ! thanks, Elise _ Free blogging with MSN Spaces http://spaces.msn.com/?mkt=nl-be

Re: [ns] Problem running wireless script
hi Alexandra,
Attached is your tcl script after modifications,it should work for you
nowby the way, I have enabled the new trace as well as nam As
for packet visualization, it is not supported yet,, to see the mobiles
movement you can run your simulation and then type:
nam simple.nam
to find more about new trace file, you can read chapter 16 of ns manual
best regards,

[ns] How to measure energy consumption of wireless nodes
Hi Gurus, I am a newbie in ns2 and I need to evaluate the energy consumption of AODV. My plan is to have the nodes send/receive data for a period of time and measure the energy difference from the beginning to the end. Could anyone instruct me how to do this. In detail: 1) How to set the energy model + initial energy correctly: some of my nodes are mobile, but I only need to measure the energy for routing/sending/receiving data. The energy for node movement is simply ignored. 2) Do I need to enable any options in ns to be able to track the energy. 3) How to read the energy from the beginning and at the end ? Please give me some detailed instructions as I am just a newbie in this field. Thanks a lot for your help. Heo - Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.

[ns] Multipath routing
Hi all, In my project i am in a need of multipath routing. Is is possible to simulate multipath routing in ns-2? If yes how? Pl Reply. Thanx in advance Vijay
Re: [ns] how can i run a wireless simulation?
Hi,
If you want to see wireless topology in nam
your have to do following addition to your scripts
first, you have to use
set namtrace [open wireless.nam w]
$ns_ namtrace-all-wireless $namtrace $val(x) $val(y)
where val(x) n val(y) should be having your grid range. or you can specilfy
it directly here like 800 800
second, just after where you declare initial node positions, you need to add
following code
for {set i 0} {$i < $val(nn)} {incr i} {
$ns_ initial_node_pos $node_($i) 30 ;
}
where val(nn) would be containing number of nodes. node_($i) is node
array and 30 denotes the size of node displayed in nam.
After this much, after simulation run, there 'll be file
wireless.namcreated. you can execute it by typing "nam
wireless.nam"
or you can add a line in your finish procedure
"exec nam wireless.nam &"
Thats it as for as topology is concerned, or node movements but
unfortunately you can't see packet flow of wireless simulation in nam.
For Xgraph files etc... See marc Greis tutorial section VIII. Creating
output files for XGraph.
Best of luck.
