• Your assignment is copied from internet, handouts or from any other student
(Strict disciplinary action will be taken in this case).

Assignment

Question No. 1 [Marks: 10]

a) You are required to install Omnet++ Simulator by providing detail of all the necessary steps.

b) Omnet++ IDE has many built in examples of simulations.
You are required to open and run any available example of TicToc by providing screen shots of each step (at least two screen shots including opening and running that example).

Note: Installation guide is available in download section on VULMS.
Question No. 2 [Marks: 10]

Simulation is one of the most significant technologies in the world that provides us the facility to get a virtual environment that behaves like a real environment without having expensive hardware and software. For this purpose we have various types of networking tools or simulators.

You are required to make comparison between the Omnet++ and NS3 simulators. Provide at least five points for each of the mentioned simulators.

Note: Your answer should be very concise and concrete. Avoid providing unnecessary detail.

Deadline: Your assignment must be uploaded/submitted on or before 14th November, 2019.

a) You are required to install Omnet++ Simulator by providing detail of all the necessary steps.

Solution
Installing OMNET++:

Download the OMNeT++ source code from
http://omnetpp.org

Make sure you select the Windows-specific archive, named omnetpp-4.6-src-windows.zip
The package is nearly self-contained, in addition to OMNeT++ files.

Copy the OMNeT++ archive to the directory where you want to install it. Choose a directory whose full path does not contain any space; for example, do not put OMNeT++ under Program Files.

Extract the zip file. To do so, right-click the zip file in Windows Explorer, and select Extract All from the menu. You can also use external programs like Winzip or 7zip. Rename the resulting directory to omnetpp-4.6.

When you look into the new omnetpp-4.6 directory, should see directories named doc, images, include, tools, etc., and files named mingwenv.cmd, configure, Makefile, and others.
Configuring and Building OMNeT++:

Start mingwenv.cmd in the omnetpp-4.6 directory by double-clicking it in Windows Explorer. It will bring up a console with the MSYS bash shell, where the path is already set to include the omnetpp-4.6/bin directory.

Then enter the following commands:
$ ./configure
$ make
The build process will create both debug and release binaries.

Verifying the installation:

You should now test all samples and check they run correctly. As an example, the dyna example is started by entering the following commands:
$ cd samples/dyna
$ ./dyna
By default, the samples will run using the graphical Tkenv environment. You should see GUI windows and dialogs.

Starting the IDE:

OMNeT++ comes with an Eclipse-based Simulation IDE. You should be able to start the IDE by typing:
$ omnetpp
To create a new empty project, open File menu, select New then select OMNET++ Project… option.
New OMNET++ Project window is opened
In Project name field give your VU ID for example
Project name:
Click on Next> button
Select Empty project and click on Finish button.
An empty project is now created. Following is the screenshot

Omnet++
Modules:
Simple Module
Compound Module
User Interface:
TKENV (GUI based)
CMDENV
Execution:
Parallel support
Language: NED

NS-2
Modules:
Modules are one inseparable unit. Also supports hierarchical models.
Interface:
GUI-based execution environment.
Language:
It is a dual-language simulator.
C++ and python.
Although it’s difficult but memory efficient.
