Accelerate NS-2 scheduler

Download: Scheduler-patch

This is a patch that can speed up the NS-2 scheduler by improving the Calendar Queue data structure in the scheduler. Especially, it can help to speed up many simulations with high speed long distance network. Some simulations that need one day with the original NS2 scheduler can now be finished in an hour.

1. Copy the patch to ns-allinone-2.28/ns-2.28 (or ns-2.29)
2. In the directory of ns-allinone-2.28/ns-2.28 (or ns-2.29) , run: make clean
3. In the directory of ns-allinone-2.28/ns-2.28 (or ns-2.29), run: patch -p1 <>
4. (Optional) delete the patch file by rm ns-scheduler.patch
5. recompile the ns2 by make and make install

Many thanks to the author: David X. Wei

***************************************************************
To install NIST mobility....

II- Version
This source files provided is for ns-2.29.


III- Installation
The mobility package is a complete ns-2.29 directory, not a patch.
Unzip and untar the source file:
tar -zxf ns-nist-mob.tgz
this will extract another compressedf file to unzip and untar:
tar -zxf ns-2.29-nist-mob-022707.tgz (this will uncompress a complete ns-2.29 directory)

Note: we have a generic name (ns-nist-mob.tgz) for download purposes. This file contains a compressed file with the release date to better keep track of the different versions.


IV- Compilation options
After extracting the ns-2.29 directory, you need to recompile the code. To do so, execute "make clean; ./configure ; make" in the ns-2.29 directory.
To debug the wimax code, edit the Makefile and add the -DDEBUG_WIMAX switch in the DEFINE entry.


V- Running examples
Examples of scenarios using homogeneous and heterogeneous handovers are located in the tcl/hsntg directory.
The scripts have been updated to run properly.

Installing INET Framework into OMNET++

Download: Inet Framework
Download: Inetmanet Framework

To install:
You should have a working OMNeT++ installation, version 4.0 or later.
It must be compiled with dynamic NED loading enabled (WITH_NETBUILDER=yes setting).

1. Make sure your OMNeT++ installation works OK (e.g. try running the samples)
and it is in the path (to test, try the command "which nedtool").

2. Change to the INET directory.

3. Type "make" to build the inet executable (debug version). Use "make MODE=release" to build release version.

Problem:
-lpcap is not found

Solution:
yum install libpcap-devel

Problem:
make: warning: Clock skew detected. Your build may be incomplete.

Solution:

   cd directory
# Remove output files
make clean
# Put timestamps on all files equal to current time
find . -exec touch {} \;
# Rebuild all output files
make

Finally, try running the demo simulations. Change into examples/ and type
"./rundemo".

Problem:
Error during startup: Cannot load library '../../../src//libinet.so': ../../../src//libinet.so: cannot open shared object file: No such file or directory.

For INET:
Solution:
SELinux blocks the library from running. Free the library with the command:
chcon -t textrel_shlib_t '/home/user/inet/out/gcc-debug/src/libinet.so'

For INETMANET:
The problem occurs due to "makefile"

1. Copy everything from "Makefile_dll" and replace all of "Makefile"

2. Execute "buildMakefiles" shell file with the command: sh buildMakefiles

3. Finally, compile with the command: make

4. You probably need this as last step:
chcon -t textrel_shlib_t '/home/user/inetmanet/out/gcc-debug/src/libinet.so'

Then you should be able to run the demo in the examples;
./rundemo

Download: Paper on NS-MIRACLE-1.2.2

NS-MIRACLE: Multi-InteRfAce Cross-Layer Extension library for the Network Simulator

NS-MIRACLE is a set of libraries designed to enhance the functionalities provided by the Network Simulator ns2. It provides an efficient and embedded engine for handling cross-layer messages and, at the same time, enables the coexistance of multiple modules within each layer of the protocol stack. For instance, multiple IP, link layers, MACs or physical layers can be specified and used within the same node. The NS-MIRACLE framework facilitates the implementation and the simulation of modern communication systems in ns2; moreover, due to its modularity, the code will be portable, re-usable and extensible.

Installation of NS-MIRACLE:

1. Unpack the nsmiracle package at /home/username and cd into the newly created directory:
Command:
tar xzf nsmiracle-1.2.2.tar.gz
cd nsmiracle-1.2.2

2. In the /nsmiracle-1.2.2, do the following:
Command:
./configure --with-ns-allinone=/home/username/ns-allinone-2.33 --prefix=/home/username --disable-static --with-dei80211mr=/home/username/ns-allinone-2.33/dei80211mr-1.1.4

3. After that, execute as following:
Command:
make
make install

4. Lastly, check that your installed NS-MIRACLE is working by running the example found in /home/username/nsmiracle-1.2.2/samples
Command:
cd samples
ns link_with_errors_cbr.tcl

You should get the result as shown if NS-MIRACLE is installed successfully:

Simulating........................................done!
Packet Error Ratio  :   0.050000
Throughput          :   68360.897567
Tracefile     : /tmp/link_with_errors_cbr.tcl.tr

NOTE:

• remember to adapt all paths to your needs, unless you're using /home/username.
• make sure that the tests run by ./configure have been successful, in particular the tests for ns-allinone
• after running make install, make sure that the path in which library have been installed is in your LD_LIBRARY_PATH environment variable.

After installing Fedora 10 with NS-2 two months back, the solution seems to have been faded from my mind. Totally cannot recall. Now my friend is having this error, yet I have forgotten how to solve it. Should have record all the solution here for reference last time but I have started this blog kinda late. Hope will soon find the solution and definitely will update in here this time!

Solution:

1. Extract tk-8.4.18-tkBind.patch from the downloaded patch.zip.
   
2. Put the file in ns-allinone-2.33 folder and in the same directory patch with the command: patch -p0 <>
3. Finally, compile the ns-2 again with the command: ./install

PS: For my case, I have to be the "root" so that ./install will compile my ns-2 completely.

OR

1. Extract tk-8.4-lastevent.patch from downloaded patch.zip.
2. Put the file in tk8.4.18 folder and in the same directory as the patch and type with the command: patch -p1 < ./tk-8.4-lastevent.patch
3. File to patch: generic/tk.h
   
4. Finally, compile the ns-2 again at ns-allinone-2.33 directory with the command : ./install

I should have blog this earlier about every obstacles and steps that have been taken upon my NS-2 experience. I hope now is still not too late yet. I hope to give this blog updated with every problems that I have faced when installing NS-2, running NS-2 and progressing with my research throughout my postgraduate studies.

Besides having this blog as a note to myself, hopefully the contents of the blog can serve as an aid to others who faced the similar problem as me. I have found blog is the most informative way for me to learn the way to start NS-2 and has helped me to solve some of my problem. Therefore, I have decided to write in my blog too to share with people and gained valuable advice from my reader.

Happy reading! That all for a short opening post. ^ ^
