Re: [ns] ns2.26 installation problem

2006-10-18 Thread Samer Bali

Hi,

ns-2.26 will only work with GCC-3.2.3 or lower. Therefore, follow these steps:
  1. Install GCC-3.2.3 (mind the 3.2.x) ( http://gcc.gnu.org/ ). To compile and 
install it is quite 
easy, simply read the INSTALL/index.html file. Then, make sure the GCC 
binary is used for the compilation of the ns-allinone package. For instance, 
set the PATH environment variable to have the directory containing the 
gcc-3.2.3 binary at the beginning.
  2. Download and compile ns-allinone-2.26.
  3. Setup your environment to use ns-2.

good luck
Samer

[ns] TKN 802.11e model and RTS/CTS

2006-10-18 Thread michelenuti

Dear NS-users,

I'd like to know if it is possible to add RTS/CTS to the 
TKN model of 802.11e for NS 2.26.
If it is possible, what do I have to do?

Thank you very much,

[ns] Diffserv: No. of physical queues

2006-10-18 Thread Vindya Amaradasa

Hi,

I want to increase MAX_QUEUES in Diffserv. When I increase the value of the 
constant MAX_QUEUES in dsred.h, it compiles fine but gives me segmentation 
fault at run time. Why would this be?

Is there anything else I have to change?

Thank you very much!

[ns] Floating point exception error

hi all ns list,
when i run tcl scripts i have this error message Floating point exception!
what does it mean  what should i do?
thanks


Re: [ns] Floating point exception error

2006-10-18 Thread Vindya Amaradasa

This error can be caused by 'division by zero'. Have a look through your 
code for any possible divisions by zero (consider worst cases).

Hope it helps!

  For TCL-level debugging you can use tcl-debug. You have to
  download it and install it in addition with ns and also when you
  ./configure
  your ns code you have to put it as a parameter, i.e. (--with-tcl-debug).
 
  For C-level debugging you can install a graphical debugger such as DDD
  (frontend for GNUDB), but at first you have to configure the
 compilation
  of ns to be prepared for debugging. You can do this by giving the
  parameter
  --enable-debug while you are configuring ns.
 
  In total, if you want both TCL-level and C-level debugging you must put
  both
  parameters
  when you execute ./configure and also install separately both
 debuggers
  (tcl-debug and
  ddd).

[ns] R: RSSI measurement

2006-10-18 Thread Marco Fiore

Loreno,

in common/packet-stamp.h you can find the PacketStamp 
structure, which is
included in any ns packet. It stores information on 
the transmitted and received
power. You can access this information 
with, for example,  p-txInfo_.RxPr,
which returns the received power 
of packet p. Note that the original implementation
of ns does not 
include interference: if you want to add this feature, you can install
the patch for wireless support you can find at http://www.reti.polito.

Marco

Re: [ns] RSSI measurement

2006-10-18 Thread Loreno Oliveira

Hi Svilen, thanks for the answer!

I will take a look at the method you said. Regarding your question, yes. I'm
working on a handoff protocol for Bluetooth. An essential point of the
protocol is the constant RSSI measurement between base stations and mobile
devices.

I am working with UCBT, which seems that does not implement RSSI measurement
between nodes. Now I am taking a better look at NS and how UCBT is
integrated to it in order to derive some way of making the RSSI
measurements...

Do you have some experience with modeling of localization experiments?? I
would be great if I could exchange some ideas with someone with some
expertise on this field...

Regards,

Loreno

 Hi,

 I do not know a tcl command about this. But you might want to look at
 WirelessPhy::sendUp, the received power Pr (in watt) is computed there
 regardless of the propagation model in use.

 Do you want to use RSSI for localization experiments in ns-2?

 Greetings,
 Svilen

Re: [ns] R: RSSI measurement

2006-10-18 Thread Loreno Oliveira

Hi Marco, very thanks to your reply!

I will take a look at the structure you said and doing some tests. Based in
what you said, probably this solves my problem. A priori I am only
considering simpler scenarios where I do not need to deal with
interferences. My actual concern is only finding a way of estimating the
distance between two bluetooth devices, and I thought RSSI was the
straingforward solution...

[ns] Need tunctl command for cygwin

2006-10-18 Thread Emin Gencpinar

Hi,

We installed ns-2 emulation (nse) both over Linux and (by cygwin) Windows
machines. NSE uses tunctl command for tun / tap interfaces to manage the
network. We have successfully installed the tunctl command source code for
Linux under sbin directory, but we could not find any tunctl command source
code valid for cygwin. Compilation error for the same source code in cygwin.

Waiting your answers as soon as possible.

Thanks all.
