Using Omnet++ in Simulating Ad-Hoc Network
Download as PPTX, PDF•14 likes•16,078 views
The document describes simulations of an AODV network using OMNeT++ and inetmanet. It will generate ad hoc networks with varying numbers of hosts from 100 to 500. Node 0 will send packets to a fixed node. It will measure the end-to-end delay for the first 700 packets received by the fixed host. The network description file defines the network components and parameters. The initialization file sets up the AODV routing protocol and network configuration. Graphs of total delay, average delay per packet, and average delay per scenario will be generated.

› Download inetmanet https://github.com/aarizaq/inetmanet-2.0
- needed for the Ad-Hoc networks
› Import projects to OmNetpp
– Create "projects" folder under "c:omnetpp"
– Extract the downloaded files to the created folder using winrar
– Import the projects using [File -> Import -> General -> Exist projects into
workspace]
– Build the projects using [Project -> Build all]
– try to run samples projects - under "examples" folder - to be sure that
previous steps are done

![Build OMNeT++ Project (2/2)
› Create new Project
– choose inetmanet as a reference in the new project properties
– be sure that inetmanet project is opened
› Create new empty network description file (.ned)
– in [Design] mode add [network]
– if we're going to use regular device add it to the network
– to create a new device based on existing - to add extra functions - one
add another ned file, in design mode add compound module
› Create an initialization file (.ini)
– use Wizard of Adhoc Mobility wireless network
– edit the parameters

Introduction to OMNeT++ 4.2.2 (1/3) › OMNeT++ is a discrete event simulation environment: – Extensible and Modular, Component-based C++ simulation library and framework, Primarily for building network simulators – Source code publicly available – Free for academic use Based on documentation from www.omnetpp.org 2/20
- 3. Introduction to OMNeT++ 4.2.2 (2/3) › Components – Simulation kernel library – Compiler for the NED topology description language – OMNeT++ IDE based on the Eclipse platform – GUI for simulation execution, links into simulation executable (Tkenv) – Command-line user interface for simulation execution (Cmdenv) – Utilities (makefile creation tool, etc.) – Documentation, sample simulations, etc. Based on documentation from www.omnetpp.org 3/20
