hello all,

friends i m an postgraduate student and want to simulate admission control
algorithm for IEEE 802.11e wireless technology please give suggestion for
this that how can i simulate this scenario. where should i have to make
changes either in .cc file or in tcl script. actually i want to use

[manonmani maligachar]

Hi all,

1.I have to use 802.16 in ns2.34. I followed the link from one of the site,
but is'nt working.
Please help me how to make 802.16 work.

2.I also have plotted a graph between to nodes which shows the lost (packet
dropped). Now how can i see packets dropped + packets sent = total packets.

3.I have simulated the VANET, but  have take RSU as one of the node, I feel
the RSU functionality should be different from the rest of the nodes. I
need some suggestions on this.

Regards
Manonmani

[Filippos Kolovos]

-
The -1 parameter means that the application will send an
arbitrarily large file (the file size will be selected randomly).
Check the NS-2 Manual, page 99, section 10.5.2 "Starting the Agent"
for more details.

Re: [ns] help needed

[anas]

firstly, you will name your file as the same name of the original one, 
ofcours you will save the original with different name, and do make
take your statistics and then go back and rename yours and rename the 
original one to the original name
and do make and take your statistics and so on,

hop it will help you

[ns] Help needed please

[Uche Kingsley]

Hi,

I'm new to ns2 and I really need help.

What I want to achieve using the ns2 is to add tags to each packets with
different priorities (high or low). When the nodes forwards the packets to
the intermediate node, the intermediate node will have a kinda filter
algorithm which will filter the packets and forward the packets with high
priority to the sink. In this case, the data in the high priority packet
will not be lost. Also plotting the graph showing the packets dropped and
throughput achieved. The nodes would be arranged like n0,n1,n2 connected to
n3(intermediated node) and n3 connected to n4(sink). Main aim is to achieve
fairness and conserve energy as well,

Thanks

[ns] Help Needed With NOAH

[Sabbir Ahmed]

Hi

I am using ns-allinone-2.1b9a on RedHat 6.2. I have
installed NOAH (old version) routing protocol
successfully. I need help regarding manual routing
with NOAH. How do I add routes manually ? Can some one
help me with examples ? The example at page
 is
for the updated version of NOAH.

One more question .. some of my scripts is working
properly with NOAH but with some I am getting
segmentation fault (these are working fine with DSDV).
Is this because I haven't set the routes ? 

Finally where is the Dumb Agent in ns-allinone-2.1b9a
... Are those included in ns-allinone-2.1b9a or later
version (I am not using gcc3.2 version of
ns-allinone-2.1b9a) ?

Regards

Sabbir

[ns] Help needed in trace file

[A Anupama]

Hi
  When an entry will be made in a trace file (for control traffic)...
If we use AODV protocol, when an entry for REQUEST will be made either when
the RREQ packet is sheduled to send or when a RREQ is received by a node (or
agent) ?
  How can we know the path followed by a node while sending data packets
? and how can we know the optimum path ?

Re: [ns] Help needed on RSVP !

[Gilles Bertrand]

Hi Deepti,

you may find the following paper useful:
/RSVP/ns: An Implementation of RSVP for the Network Simulator ns-2/ - 
Marc Greis - http://www.sti.uniurb.it/acquaviva/didattica/rsvpns.pdf

The adaptations of this RSVP\ns to recent version of NS (<=2.26) are 
provided on R. Prior's web page:
http://www.ncc.up.pt/~rprior/ns/index-en.html

Alexander Sayenko seems to have updated this tool to the last versions 
of NS (2.27 and 2.28). I have not tested it for the moment 
(http://www.cc.jyu.fi/~sayenko/src/).

[ns] Help needed for ns2HCCA patch

[Ritwik Mitra]

   Hello 

 I am working on a project on 802.11E schedulers. I am trying to implement 
ARROW and SETT-EDD schedulers with some minor modifications, using the ns2HCCA 
patch for NS-2.27.
 
 However, I am facing the following problems:
 
 1. Where (in the code) does a CAP start mechanism take place. There is a 
startCAP(void) function in mac-802_11e.cc file, but it is called twice. Once, 
when we specify start-hcca in the TCL  script and second time when we pass the 
TSPEC parameters in the TCL script.
 Is this function called only when the QAP starts a CAP?
 
 2. How does the patch ensure that the TXOP list that is created is being 
followed fully. Consider the offline TXOP list that is created. Suppose it 
contains the TXOP times for the stations 1,2,5,6. How does the patch ensure 
that first only station 1 will access the channel, and then stations 2, 5, 6 
... and so on. How is this being ensured?
 
 3. How do the stations get access to the channel i.e. how does the channel 
access switch mechanism take place. E.g. Suppose at time t station 1 is 
accessing the channel. After time t+t1 , i want station 2 to access the 
channel. How can i do that? 
  
 I would be really grateful if anyone could explain me the working of the patch 
w.r.t the questions mentioned above. Also, any suggestion as to how to go about 
implementing the ARROW scheduler would be welcome.
 
 Thanks in advance.

[ns] Help needed for "Application/Traffic/Trace"

[piyush sharma]

Hi ns-users,

I am trying to use the 'example-trace' file located in the ns-2.28/tcl/ex/
directory for generating traffic. I am using the following commands in my
tcl script, but the trace file generated after the simulation is blank.

Please help!
Thanks!

set tfile [new Tracefile]
$tfile filename example-trace
set t1 [new Application/Traffic/Trace]
$t1 attach-tracefile $tfile

I have put the file 'example-trace' in the directory from where  I am
running ns.

[ns] help needed to downgrade GCC version

[Martin Dario Pereyra]

  Hi all, I have a problem when installing old gcc version. I use
ns-allinone-2.27 with NRLSensorSim extension (2.27 is the most recent
version for this extension) in Fedora Core 6 with gcc 4.1. I have a patch
for this version of ns to work with gcc 4.1 but for the extensions added
doesn't work.
 So I want to install an alternate gcc compiler on my fedora (gcc 2.95) like
a solution. This two packages:

gcc-core-2.95.tar.gz
gcc-g++-2.95.tar.gz

i do gcc configure:

/home/mpereyra/gcc/gcc-2.95/configure \
--prefix=/opt/gcc295 \
--program-suffix=295 \
--enable-languages=c,c++ \
--enable-shared --enable-threads=posix --disable-cheking \
--with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions

and when i do 'make' this is the error:

/home/mpereyra/gcc/gcc-2.95/gcc/frame.c:55: extra brace group at end of
initializer
/home/mpereyra/gcc/gcc-2.95/gcc/frame.c:55: (near initialization for

("se sale del directorio" means 'leaving directory')

I Think that some paremeters of gcc configure are not ok. What do you think?

Re: [ns] help needed to downgrade GCC version

[Mohammad Zubair Ahmad]

This is a problem with the gcc version. I had a lot of problems recently
when I tried to install the NRL extensions with the ns 2.27 version.
Downgrading gcc is not actually an easy task (as I discovered). Google up
some gcc forums and follow steps provided there. I will look again for the
link I used and let you know if I find it.

Simple solution to the problem though -  Use fedora 2. The whole sensor net
extension and ns installation gets done without problems in 15 mins. Just a
quick hack to your problem .. :)

Install gdb or ddd, make sure you compiled ns with debugging symbols,
start your debugger and let the program crash. Check the backtrace to see
at which point it stopped working, set a breakpoint and start
investigating while you're stepping through the code from that point on.

If you've never worked with gdb/ddd before, it might look a little bit
difficult at first but it's an absolute necessity for any serious
programmer to master it. There are some excellent tutorials out there. As
a starter, I'd recommend these

http://heather.cs.ucdavis.edu/~matloff/UnixAndC/CLanguage/Debug.html
http://www.unknownroad.com/rtfm/gdbtut/gdbtoc.html

for gdb and this one

http://heather.cs.ucdavis.edu/~matloff/Debug/Debug.pdf [PDF slideshow]

for ddd.


Good luck!

[ns] Help needed on Multiple interface support in 802.15.4

[Lupe Krops]

Dear all,

I'm trying to implement multiple interface support for 802.15.4 networks using 
Ramon's Calvo guide 
(http://personales.unican.es/aguerocr/files/ucMultiIfacesSupport.pdf). Their 
work concerns 802.11
networks, so I need to make the appropriate changes to include 802.15.4 
networks. In the document,
among other files, they have edited the recv method in the mac-802_11.cc file. 
I tried to change the
relevant mac 802.15.4 file, however unsuccessfully, as I cannot identify where 
the change should take
place. I will be thankful if someone can guide me on how to make the 
appropriate changes in order to
implement multiple interface support in 802.15.4 networks and also let me 
know if there is the need to 
change files other than the ones listed in the relevant guide.

Thank you in advance.

Best regards,
Lup.

[ns] Help needed for HCCA patch on NS-2.27

[Ritwik Mitra]

Hi!
 
 I downloaded and installed the HCCA patch for NS-2.27 from 
http://info.iet.unipi.it/~cng/ns2hcca/ 
 
 However, I am not able to find out how the stations get the access to the 
channel. Consider the offline TXOP list that is created. Suppose it contains 
the TXOP times for the stations 1,2,5,6. How does the patch ensure that first 
only station 1 will access the channel, and then stations 2, 5, 6 ... and so 
on. 
 
 If anybody can throw some light on this issue, I'll be really grateful.
 Thanks in advance

Re: [ns] Help needed, Problem in installing NS-allinone-2.27 in linux

[Adrian Sai-wah Tam]

Are you using x86_64 architecture (i.e. fairly new AMD cpu)?
Probably the source code is not supposed to be used on this arch.

[ns] help needed in performance comparison of AODV, DSR and DSDV routing protocol

[ankur goyal]

Hi All,

I have written a tcl script and an awk script to evaluate the performance of
AODV, DSR and DSDV protocols in terms of average delay and total number of
packets received and dropped. But i am getting very absurd results when i
run my script to extract the data.

My results are as follow:

for DSR:

  Generated Packets = 46904 PACKETS
  Received Packets = 1227 PACKETS
  Total Dropped Packets = 12443
  e2e delay = 3.911883

for AODV:

  Generated Packets = 12362 PACKETS
  Received Packets = 3221 PACKETS
  Total Dropped Packets = 9105
  e2e delay = 0.007428

I believe that there is something wrong in my script which i am not able to
figure out.

So can anyone provide me a tcl script for AODV, DSR and DSDV protocols such
that all the required data are extracted from trace files in TCL scripts
only rather than using AWK script separately.

Eagerly waiting for a quick reply as i need it urgently.

Thanks & Regards,
Ankur

1) i need to make a cluster with two types of nodes( types in terms of 
priority, 1 is transmitter and other is transceiver) and a sink node 
2)on sink and source nodes i need to configure PNRG (pseudo random number 
generator strategy) and nodes need to share their seed value, node ID etc with 
sink so that sink can schedule transmission schedule for nodes. how to make it 
work on ns-2 ?


 i am attaching my paper please suggest how to start coding for it in ns-2.
