Detailed Analysis of OMNeT++ Installation, Protocols, and Security

This report provides a detailed overview of the OMNeT++ network simulation environment. It begins with a step-by-step guide to installing OMNeT++ on a Windows operating system, including the necessary software versions and commands. The report then delves into the core concepts of network protocols, explaining message conversation, division, multiplexing, and the importance of protocol suites. Security aspects are also discussed, focusing on encryption and decryption using AES and RSA algorithms, along with the implementation of WebSockets for secure communication. The report further outlines research questions related to security concerns, fault identification, and the development of secure vehicular social networks. It lists communication, broadcasting, and counter-based protocols, and concludes with a discussion on standards governing communications, emphasizing the layered approach to network protocols and the interaction between application and transport protocols such as HTTP and TCP. The report also describes the use of layers in depicting communication and provides an overview of protocols at the network level, including the structure and organization of messages, and how they interact within a network environment.

OMNET++ EXECUTION

1. Software versions
 OMNET : OMNETPP-4.6.
 JDK : JDK 1.8.
 OS : WINDOWS
2. Installation procedure
Step 1: check your os version help the command is “dxdiag”
Click “ok” button

Double click “mingwenv.cmd” file
Ask security warning so click “run” to proceed
Click “run” to proceed
Step 5: next type 3 commands to install omnetpp into your Network, there are
1) . Setenv
2) ./configure
3) make

3. Setting up the project
Start the OMNeT++ IDE by typing omnetpp in your terminal. Once in the IDE,
choose New -> OMNeT++ Project from the menu.
4. Adding a C++ files
Open a Files by choosing File--Open---- Source Files
5. Simulation program’s Launch
After all the above mentioned steps are completed, the simulation can be
launched with the selection of %omnetpp.ini (either the editor area or the Project
Explorer). Then, press on the button stating, Run.

6. Protocol for Message Conversation
Conveying Messages
Solitary communication is a principle. For example, the music video or the email
message, can be sent over the Network from the source to the destination as one enormous
persistent stream of bits. If the messages were really sent via this way, it implies that no other
device will contain the capacity of sending or receiving the messages on a similar Network,
when this information movement was processing. Such vast floods of information will end up
with huge delays. Then, in case the interconnected Network framework‘s connection failed
during transmission, there are possibilities of losing the total message and this message has to
be fully retransmitted. A superior method includes separating the information into small and
highly sensible pieces for sending over the Network. Such a division of information stream
into little parts is known as division. Sectioning messages contains a couple of essential
advantages. To start with, by sending the individual smaller pieces from the source to the
destination, on the Network a wide range of discussions could be interleaved. The procedure
