  1. 1. onOMNeT++ Submitted By: Rahul Gupta
  2. 2. Outline Introduction What is OMNeT++? Platforms Simulation Models Working with OMNeT++ Applications of OMNeT++ Conclusion
  3. 3. Introduction Discrete event simulator  Hierarchically nested modules  Modules communicate using messages Written in C++  Source code publicly available  Simulation model for Internet, IPv6, Mobility, etc. available Free for academic use  Commercial version of OMNESTTM Pros  Well structured, highly modular, not limited to network protocol simulations
  4. 4. What is OMNeT++? OMNeT++ is a public-source, component-based, modular and open-architecture simulation environment with strong GUI. OMNeT++ provides a component architecture for models. Components (modules) are programmed in C++, then assembled into larger components and models using a high- level language (NED). OMNeT++ is free for academic and non-profit use; commercial users must obtain a license from Omnest Global Inc.
  5. 5. Platforms OMNeT++ runs well on  Linux  most other Unix-like systems  Win32 platforms (NT4.0, Window 2000, XP). Third party software  C++ compiler  Tcl/Tk  Perl  GraphViz  Ghostscript  UnxUtils  LibXML/LibXSLT
  6. 6. Simulation models INET Framework The INET Framework is an open-source communication network simulation package for the OMNeT++ simulation environment. It contains models for several wired and wireless networking protocols. Mobility Framework Supports wireless and mobile simulations within OMNeT++. The core framework implements the support for node mobility, dynamic connection management and a wireless channel model. IPv6Suite IPv6Suite is an OMNeT++ model suite for accurate simulation of IPv6 protocols and networks.
  7. 7. Working With OMNeT++1. An OMNeT++ model is build from components (modules)which communicate by exchanging messages. Modules can benested, that is, several modules can be grouped together to forma compound module. When creating the model, you need to mapyour system into a hierarchy of communicating modules. 2. Define the model structure in the NED language. You can edit NED in a text editor or in the graphical editor of the Eclipse-based OMNeT++ Simulation IDE. 3. The active components of the model (simple modules) have to be programmed in C++, using the simulation kernel and class library. 4. Provide a suitable omnetpp.ini to hold OMNeT++ configuration and parameters to your model. A config file can describe several simulation runs with different parameters. 5. Build the simulation program and run it. Youll link the code with the OMNeT++ simulation kernel and one of the user interfaces OMNeT++ provides. There are command line (batch) and interactive, graphical user interfaces.
  8. 8. ApplicationsOMNeT++ is an object-oriented modular discrete event network simulator. It can be used for: Traffic modeling of telecommunication networks. Protocol modeling. Modeling queuing networks. Modeling multiprocessors and other distributed hardware systems. Validating hardware architectures. Evaluating performance aspects of complex software systems.
  9. 9. Conclusion OMNeT++: Component based simulation system OMNeT++ is a  public-source,  modular and open-architecture simulation environment  with strong GUI support and OMNeT++ 4.1 IDE (Eclipse)
