Running NS-2Ns-2 can be run both in windows or Linux platform.
- Use Linux
How to run NS-2 under Windows?
- Using Cygwin (not recommended)
- Using Virtual machine
- Vmware station (not free)
- WM player (free and recommended)
- Virtualbox (free)
download the latest ns2 copy . their are two methods to do that
1. go to terminal and type
wget http://nchc.dl.sourceforge.net/sourceforge/nsnam/ns-allinone-2.34.tar.gz2. u can download it from here
Step 2: Extract
extract the tar file in home directory i.e. /home/username
try this in terminal
tar -xzvf ns-allinone-2.34.tar.gzstep 3 :install
just type following commands
cd ns-allinone-2.34 sudo apt-get install build-essential autoconf automake libxmu-dev ./installStep 4: Set environment variables
$ gedit ~/.bashrcAdd the following lines to the end of the file. Remember replace “/your/path” by the folder where you have stored extracted the ns-2 file
# LD_LIBRARY_PATH OTCL_LIB=/your/path/ns-allinone-2.34/otcl-1.13 NS2_LIB=/your/path/ns-allinone-2.34/lib X11_LIB=/usr/X11R6/lib USR_LOCAL_LIB=/usr/local/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB # TCL_LIBRARY TCL_LIB=/your/path/ns-allinone-2.34/tcl8.4.18/library USR_LIB=/usr/lib export TCL_LIBRARY=$TCL_LIB:$USR_LIB # PATH XGRAPH=/your/path/ns-allinone-2.34/bin:/your/path/ns-allinone-2.34/tcl8.4.18/unix:/your/path/ns-allinone-2.34/tk8.4.18/unix NS=/your/path/ns-allinone-2.34/ns-2.34/ NAM=/your/path/ns-allinone-2.34/nam-1.14/ PATH=$PATH:$XGRAPH:$NS:$NAM
Ensure that it immediately takes effect:
$ source ~/.bashrc
Note: the previous step is important; else you cannot successfully run ns-2.
(Alternatively, you may have to restart your X-windows, that is logout, and then login, or restart your computer.)
Now, the installation has been completed. Try:
$ nsThe “%” symbol appears on the screen. Type “exit” to quit.
Validation (optional)To run the ns validation suite:
$ cd ns-2.34 $ ./validate
Configuring Eclipse to work with NS2
For most users of NS2, it would be easier if they can use a popular IDE to work with the files.
Here are the step by step instructions to set up NS-2.34 with Eclipse 3.5 in Ubuntu Linux.
Setting up Eclipse:
- Download Eclipse SDK
- Extract the SDK to a folder
- Open Eclipse
- Go to Help -> Install New Software. In the Work With bar type this:
- Choose CDT Main Features and CDT Optional Features. Install them.
CDT stands for “C/C++ Development Tooling”
- If you do not have a working internet connection in the system you have installed Eclipse, instead of steps 4 and 5, download the CDT from the above mentioned site. Then move to Install New Software (see step 4) -> Add and add the archive downloaded.
Enabling debugging in NS2
- Edit Makefile:
- Open “…/ns-allinone-2.34/ns-2.34/Makefile.in”and
- Add these lines anywhere near the top of the file:
CCOPT = -g
DEFINE = -DNDEBUG
DEFINE = -DDEBUG
- Navigate to …/ns-allinone-2.34/ns-2.34 and run “./configure”
- Navigate to the NS-2 folder using terminal and type ./install
- Also, follow the instructions are displayed at the end of a successful installation. These instructions are to modify the PATH variable and other environment variables as needed.
- Open Eclipse
- Set the workspace as the ns installation path( /home/username/ns-allinone-2.34 ) by selecting File -> Switch Workspace
- Choose File -> New -> Project -> C++ Project
- Select Project Type as Makefile Project -> Empty C++ Project.
Toolchains: Linux GCC
- Enter Project Name as ns-2.34
- Uncheck “Use default location” then browse to the directory NS-2 source directory ( …/ns-allione-2.34/ns-2.34 )
- Select “Next” and “Finish.
- From the workspace, Selecting the NS-2 Project and choosing Project -> Build All should not give Error.
- Running the project must open the console with the NS-2 prompt, %
- Select Run -> Debug Configurations
- Choose C/C++ Application. Type in any name.
- Under the Main tab, Choose the following:
Project as ns-2.34.
C/C++ Application as ns. (Search Project and Choose this)
- Under the Debugger tab, choose GDB Debugger. Uncheck the “Stop on startup at” option.
- Apply and Debug.
Update from Readers: Changes to be made in Makefile.in file:
Add -g to the line
CCOPT = @V_CCOPT@
CCOPT = @V_CCOPT@ -gAdd
-DNDEBUG -DDEBUGto the end of the following line:
DEFINE = -DTCP_DELAY_BIND_ALL -DNO_TK @V_DEFINE@ @V_DEFINES@ @DEFS@-DNS_DIFFUSION -DSMAC_NO_SYNC -DCPP_NAMESPACE=@CPP_NAMESPACE@-DUSE_SINGLE_ADDRESS_SPACE -Drng_test -DNDEBUG -DDEBUG
Apart from doing "make clean" every time you make changes to the c++ files, you can just delete the *.o files in that folder and just do make only. This will save your development time.
