hope you all will be at quiet ease!
Please do me a favour>
I have problem in installing OWNS (package for Optical wavelength division
multiplexing in ns).
I have done all steps of the instructions given below except 6th instruction.
Please tell me what to do in this.
execution with out this step gives error : path enviroment not set for NS-2
The proceduer i am following is here:

OWns Installation Guide
_________________________________________________________________________
Installation package: owns.tar
This installation guide of OWns is based on ns-allinone-2.1b6,
and has been tested on RedHat Linux 6.x 7.x. Other
ns versions and platforms have not been tested.
Note : The easy installation package which was available earlier has been
discontinued.
Advanced Installation
_________________________________________________________________________
1. Copy the "owns.tar" file to your "ns-allinone-2.1b6/ns-2" directory.
2. Untar "owns.tar" which creates the directory "OWNS/" in your ns-2
directory.
You will find the following directory structure under OWNS
ns-2 - This dir holds the C++ source files.
tcl - This dir holds the tcl files
modified - This dir contains files which are part of the ns distribution
that you need to *modify* individually. The files in this directory have
already been modified.Please do *NOT* replace the original files with
these files. Replacing the files may result in losing the additions
to the newer versions of ns.
3. Install sgb2ns tool for WDM network topology generation tools.
a. Copy the file "OWNS/sgb2comns-wdm.c" to
the directory "ns-allinone-2.1b6/gt-itm/sgb2ns/".
b. Update the "Makefile" in the "gt-itm/sgb2ns" directory accordingly as
follows.
Add the following lines into "Makefile":
COMN_WDM = sgb2comns-wdm.o
sgb2comns-wdm: $(COMN_WDM)
$(CC) $(CFLAGS) -o $(BDIR)/sgb2comns-wdm $(COMN_WDM) $(LIBS)
sgb2comns-wdm.o : $(CH)
Note: A copy of the the modified file "Makefile.sgb2ns" is available in
"OWNS/modified/"
4. Install C++ files
a. New files : These files are already present in the "OWNS/ns-2/" dir.
Please verify that they do exist.
b. Modify "agent.h" and "agent.cc" in "ns-allinone-2.1b6/ns-2.1b6".
You need to manually add the new code of OWns to these two files.
Use the key word "OWNS" to search for the OWns code in the corresponding
files "agent.{cc,h}" in the "OWNS/modified/" directory.
c. New WDM packet header - C++ side changes
Insert the following two lines into "ns-allinone-2.1b6/ns-2.1b6/packet.h"
file.
PT_PING,
PT_WDM, <== new line
name_[PT_PING] = "ping";
name_[PT_WDM] = "wdm"; <== new line
d. Update the makefile "ns-allinone-2.1b6/ns-2.1b6/Makefile.in".
Add the following objects to "OBJ_CC = \":
OWNS/ns-2/classifier-addr-lightpath.o \
OWNS/ns-2/wdm-route.o \
OWNS/ns-2/session-trafgen.o \
OWNS/ns-2/cbr_session_traffic.o \
OWNS/ns-2/expoo_session.o \
OWNS/ns-2/wdm-wassign.o \
OWNS/ns-2/fiber-delay.o \
OWNS/ns-2/session-traf-rcvr.o \
OWNS/ns-2/wdm-agent.o
A copy of the modified "Makefile.in" is available in the "OWNS/modified"
directory.
d. Update the "install" file in ns-allinone-2.1b6 directory.
Add the following line:
......
ln -s $CUR_PATH/gt-itm/bin/sgb2comns sgb2comns
ln -s $CUR_PATH/gt-itm/bin/sgb2comns-wdm sgb2comns-wdm <== New line
ln -s $CUR_PATH/gt-itm/bin/itm itm ......
The modified "install" file is available in the "OWNS/modified" directory.
5. Install tcl files
a. New files : These files are already present in the "OWNS/tcl/" dir.
Please verify that they do exist.
b. Modify "ns-lib.tcl" in "ns-allinone-2.1b6/ns-2.1b6/tcl/lib"
directory.
You need to manually add the new code as follows.
...............................
source ../emulate/ns-emulate.tcl
#
# OWns script
#
source ../../OWNS/tcl/ns-wdm-link.tcl
source ../../OWNS/tcl/ns-wdm-node.tcl
source ../../OWNS/tcl/ns-wdm-route.tcl
source ../../OWNS/tcl/ns-wdm-wassign.tcl
source ../../OWNS/tcl/ns-wdm-source.tcl
source ../../OWNS/tcl/ns-wdm-default.tcl
#
# End of OWns script
#
Simulator instproc init args {
......................
c. New WDM packet header - OTcl side changes
Insert the following line into
"ns-allinone-2.1b6/ns-2.1b6/tcl/lib/ns-packet.tcl" file.
{ Ping off_ping_}
{ WDM off_wdm_} <== new line
6. Rebuild ns using "install", and update environment variables,
"PATH" and "NS-2". For example, in C shell:
setenv PATH "ns-allinone-2.1b6/bin:$PATH"
setenv NS-2 "ns-allinone-2.1b6/ns-2.1.b6"
setenv LD_LIBRARY_PATH "ns-allinone-2.1b6/otcl-1.0a5"
=======================
Known Problems
=======================
1. Bandwidth of link and traffic
DO NOT use the high bandwidth like 1Gb or 1000Mb, please use the
scaled traffic and single wavelength bandwidth, say 1Mb.
2. Number of wavelengths per fiber
Currently, the maximum number of wavelength per fiber is 64.
The current implementation of RWA algorithm needs to be
improved to reduce memory usuage.
