ns-3 environment setup - python

Python

- Python is a general purpose high level programming language. It support multiple programming paradigm as object-oriented programming.

Python features:

- Fully dynamic type system.

- Automatic memory management as Perl, Ruby, Scheme and Tcl.

ns-3 object aggregation

Problem:

Coupling between models hinders software reuse in different configurations.

-must intrusively edit the base class for this

-or, leads to C++ downcasting

-know as the C++ "weak base class" problem

So, what is base class?

It is a class that had no superclass and usually at base of tree of subclasses.

ns-3 solution: an object aggregation model

-object can be aggregated to other objects at run-time

-a "query interface" is provided to ask whether an particular object is aggregated

-similar in spirit to COM or Bonobo object

but keep in mind that aggregation is different from composition.

What is ns-3?

ns-3 is a discrete-event simulator for internet system. It's intention is to study Internet protocols and large-scale systems in controlled environment. It will be a new simulator to replace ns-2.

3. Under your ~/wimaxrepos directory, type the following

./download -n iamine/ns-3-wimax-release

or

./download.py -n iamine/ns-3-wimax-release

4. You are now ready to build the ns-3 distribution.

itpp @ IT++

1. What is itpp @ IT++?

Please refer http://sourceforge.net/apps/wordpress/itpp/

2. Installation?

For Debian GNU/Linux package as Ubuntu, use the following command

sudo apt-get install libitpp-dev libittp-doc

3. debug configure ns-3-wimax-release

Status:

WiMAX : enabled

LIBXML

1. Download for LIBXML2 at ftp://xmlsoft.org/libxml2/

2. Extract and cd to libxml2.x.x.

3. Use the following commands:

./configure

make

make install

4. ./waf -d debug configure

Check for LIBXML2 : ok

ns-3 terms

5. Topology Helpers

Checking for pkg-config flags for GSL : not found

Checking for pkg-config flags for GSL : not found

1. What is GSL?

It is GNU Scientific Library (GSL).

2. Download GSL package and extract it.

3. Read the READ file then the INSTALL file. Use the following commands

./configure

make

make install

opss... need permission. so type

sudo make install

then, insert the root password. Finish installing GSL.

3. Back to ns-3-wimax folder. Debug configure again.

./waf -d debug configure

result:

Checking for pkg-config flags for GSL : ok

ns-3-wimax installation...

1.Doing installation of ns-3-wimax-release on linux machine. Follow through the tutorial provided.

Some problem when doing regression test (something like regression trace not found I guess). So, re-download the ns-3-wimax-release with ns-3-dev-ref-traces:

./download.py -r ns-3-wimax-release -r ns-3-dev-ref-traces

2.Next, doing regression testing again and tests passed.

3.Just trying run some script hello-simulator and output is produced.
