 Course Overview: Network Simulation with OMNeT++

This course provides a comprehensive introduction to Discrete Event Simulation
(DES) using OMNeT++. OMNeT++ is a modular, component-based C++ simula-
tion library and framework primarily for building network simulators.
Students will learn how to model communication protocols, simulate network behavior, and analyze system performance. The course emphasizes practical implementation,
focusing on realistic, contemporary network scenarios such as:

  • Wireless Sensor Networks (WSNs)
  • Unmanned Aerial Vehicles (UAVs)
  • Vehicular Ad-hoc Networks (VANETs)

 

🎯 Course Objectives

  • Define the fundamental concepts of discrete event simulation (DES) as ap-
    plied to communication networks.
  • Use the NED language effectively to create simple and compound modules
    in OMNeT++.
  • Implement module behaviors using C++ programming, including functions
    such as handleMessage().
  • Configure simulations through the omnetpp.ini file and understand key run-
    time parameters.
  • Simulate wired networks (Ethernet, TCP/IP, UDP) and wireless networks
    (WiFi) using the INET framework.
  • Integrate realistic mobility models (e.g., VANET, UAV) and energy consump-
    tion behavior into network scenarios.
