[ns] patch Wi-Max installation with Cygwin

2006-11-28 Thread Elena Putzolu 

Hi all,
I am trying to install the Patch NIST' S WIMAX Model on Cygwin for Ns-2 .29 
through the commands
-p0 patch-wimax-prerelease-092206 
-p1 patch-wimax-prerelease-092206 
but both do not work. 
can someone help me? 
thanks in advance

[ns] problem with Patch Wimax

2006-11-30 Thread Elena Putzolu 



thanks all,
I have tried the command -p0  patch-wimax-prerelease-092206 
 from the ns-allinone-2.29 directory
while the command  -p1 patch-wimax-prerelease-092206 
from the ns-2.29 directory, but doesn't work.
I have tried the command patch patch-wimax-prerelease-092206  and appears 
can't find file to patch at input line 4
perhaps you should have used the -p pr --strip option?
the text leading up to this was:
diff -Naur ns-2.29-0rg/common/packet.h   ns-2.29/common/pachet.h
---ns-2.29-org/common/packet.h
+++ ns-2.29/common/packet.h
file to patch:


I sincerely do not know how to interpret them because I am not very expert of 
Linux commands .
Bye

finally I have installed Patch NIST' S WIMAX 
then however I have tried the simple.tcl  example  in the  
/usr/Local/Ns-Allinone-2 .29/ Ns-2 .29/ Tcl/Wimax/ Directory, but a the command
ns simple.tcl
I obtain as answer :
command name Mac/802_16
  while executing

[ns] problems with installation Ns-2 .29.3 under Cygwin

2006-12-06 Thread Elena Putzolu 

Hi all,

when I did the ./validate, I obtained: 

These messages are NOT errors and can be ignored:

warning: using backward compatibility mode

This test is not implemented in backward compatibility mode

 


validate overall report: some tests failed:

 ./test-all-smac-multihop ./test-all-simultaneous ./test-all-wireless-tdma

to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME

Notice that some tests in webcache will fail on freebsd when -O is turned on.

This is due to some event reordering, which will disappear when -g is turned on.

 

Cygwin = 1.3.19 detected (1.5.21), all tests should have passed.

Please see http://www.isi.edu/nsnam/ns/ns-problems.html

for potential solutions.

Then with the Echo $PATH command I have had as answer: 

/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/Programmi/ATI
 Technologies/ATI Control Panel:/usr/lib/lapack
I think that my Paths are set wrong , but   I have given in the Ns-Allinone-2 
.29 Directory the order: 

export PATH= 
/usr/local/ns-allinone-2.29/bin:/usr/local/ns-allinone-2.29/tcl8.4.11/unix:/usr/local//ns-allinone-2.29/tk8.4.11/unix

Where am I making a mistake? I thank you so for lo help which you are giving me

[ns] Problem with Pach WiMax installation under Cygwin

2006-12-08 Thread Elena Putzolu 

Hi all,
I run the command
patch -p0  patch-wimax-prerelease-092206 in ns-allinone-2.29 directory. Then, 
after the ./configure, I added in the Makefile  --DDEBUG_WIMAX to the DEFINE 
command (somewhere around line 62).
then I did:
$ make clean
and
$ make
g++ -c -g -Wall -Werror -Wall  -DTCP_DELAY_BIND_ALL -DNO_TK 
-DTCLCL_CLASSINSTVAR \   -I. -I/usr/local/ns-allinone-2.29/tclcl-1.17

./autoconf.h:89: error: expected namespace-name before ';' token
./autoconf.h:89: error: `type error' is not a namespace
make: *** [tools/random.o] Error 1

when I did make install, the result was:

$ make install
for d in /usr/local/man/man1; do \
if [ ! -d $d ]; then \

fi;\
done
/usr/bin/install -c -m 755 ns /usr/local/bin

therefore when I did:
$ ns simple.tcl

while executing
Mac/802_16 set debug_ 0
(file simple.tcl line 45)

what is there that he does not go?

[ns] WiMax Patch installation...help!

2006-12-09 Thread Elena Putzolu 

Hi all,

In the ns-2.29 directory, I did:
make clean; ./configure  -enable-debug; make
the result (after many lines) was:
trace/trace.cc: In member function `virtual void DequeTrace::recv(Packet*, 
Handler*)':
trace/trace.cc:567: warning: int format, nsaddr_t arg (arg 5)

trace/trace.cc:586: warning: int format, nsaddr_t arg (arg 6)
make: *** [trace/trace.o] Error 1

then I edit the Makefile  and add the -DDEBUG_WIMAX switch in the DEFINE entry.
at last I run
ns simple.tcl(example in /tcl/wimax directory) but the result was :
invalid command name Mac/802_16
while executing
Mac/802_16 set debug_ 0
(file simple.tcl line 45)

In the site it is explained that recompiling the whole system, thing is 
necessary he means?

 hi,

 I am going to simulate 802.11a channels in NS2, but i couldn't find out  
 any tutorials about 802.11a in NS2. Could anyone help me some guides or

Hi Toan,
How to set up the wireless bandwidth (such as 802.11 a,b,g) in NS2?
Answer:

In ns2.26 and ns2.27, you can change (basicRate_ and dataRate_ ):

Mac/802_11 set basicRate_ 1Mb
Mac/802_11 set dataRate_  11Mb

in your tcl script.

FHSS (IEEE802.11a)
  Mac/802_11 set SlotTime_  0.50;# 50us
  Mac/802_11 set SIFS_  0.28;# 28us
  Mac/802_11 set PreambleLength_0   ;# no preamble
  Mac/802_11 set PLCPHeaderLength_  128 ;# 128 bits
  Mac/802_11 set PLCPDataRate_  1.0e6   ;# 1Mbps
  Mac/802_11 set dataRate_  1.0e6   ;# 11Mbps
  Mac/802_11 set basicRate_ 1.0e6   ;# 1Mbps

DSSS (IEEE802.11b)
  Mac/802_11 set SlotTime_  0.20;# 20us
  Mac/802_11 set SIFS_  0.10;# 10us
  Mac/802_11 set PreambleLength_144 ;# 144 bit
  Mac/802_11 set PLCPHeaderLength_  48  ;# 48 bits
  Mac/802_11 set PLCPDataRate_  1.0e6   ;# 1Mbps
  Mac/802_11 set dataRate_  11.0e6  ;# 11Mbps
  Mac/802_11 set basicRate_ 1.0e6   ;# 1Mbps

Note:

-if using the short preamble option: you can change the line as:
Mac/802_11 set PreambleLength_ 72

-  # frequency is 2.4 GHz
  Phy/WirelessPhy set freq_ 2.4e+9
  # transmit power
  Phy/WirelessPhy set Pt_ 3.3962527e-2
  # Receive sensitivity.
  Phy/WirelessPhy set RXThresh_ 6.309573e-12
  Phy/WirelessPhy set CSThresh_ 6.309573e-12

Note that the radio range that results from this configuration may or may
not coincide with open field tests. If you want setup a specific range,
use the program ~/indep-utils/propagation/threshold.cc to obtain the
desired RXThresh_ (rx sensitivity) based on the above frequency, transmit
power and your desired range.


802.11g:

#define DSSS_CWMin15
#define DSSS_CWMax1023
#define DSSS_SlotTime0.09
#define DSSS_CCATime 0.03
#define DSSS_RxTxTurnaroundTime0.02
#define DSSS_SIFSTime0.16
#define DSSS_PreambleLength 96
#define DSSS_PLCPHeaderLength40
#define DSSS_PLCPDataRate6.0e6// 6Mbps
#define DSSS_MaxPropagationDelay 0.005// 0.5us

Note: bandwidth is different with achievable throughput.

- In NS ACK are always sent at 1Mbps
- NS use always the long PLCP preamble format sent at 1Mbps
- by default NS uses RTS/CTS handshake
- Packet's size has also an impact in the % of overhead.

All this factor can  bound the achievable throughput

[ns] configuration 2 interfaces (in 2 different channels) with 802.11a and 802.11b

thanks Marcel,
but my demand did not refer to the values that variable statics must 
assume (the values they can modify easy), I need help for  the 
interface  set up in tcl languages.
Which are the commands who allow me to shape in way corrected the static 
tcl variable for every interface and in every channel from defined me 
(chan_a_, chan_b_). And moreover, Where I must put these commands in my 
script in way cha the configuration it is valid?
You can help me in this?
