Omnet++ Presentation Transcript

  • 1. Network Simulator using inetmanet for OMNeT++ 4.2.2 AODV as an Ad-Hoc Routing Protocol November 14, 2012 Ahmed A. Nour, Ahmed ElSaher, Ehab ElShafei, Tarek Mohamed Nile University – CIT623 – Security in Wireless Ad-Hoc Networks
  • 2. 2/20 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
  • 3. 3/20 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
  • 4. 4/20 Introduction to OMNeT++ 4.2.2 (3/3) › OMNeT++ does not provide any components specifically for network simulations › various simulation models and frameworks such as INET/INETMANET, MiXiM, or Castalia - developed completely independent of OMNeT++ - provide support for: – computer network simulations – queuing network simulations – system architecture simulations
  • 5. 5/20 Working with OMNeT++: Flow Chart (1/2) 1 • Model is built from components (modules) which communicate by exchanging messages. Modules can be nested. several modules can be grouped together to form a compound module 2 • The model structure in the NED language is defined. Could be edited in a text or graphical editor of the Eclipse-based OMNeT++ Simulation IDE 3 • The active components of the model (simple modules) have to be programmed in C++
  • 6. 6/20 Working with OMNeT++: Flow Chart (2/2) 4 • omnetpp.ini holds OMNeT++ configuration and parameters to a model. A config file can describe several simulation runs with different parameters 5 • The simulation program is built then run. You'll link the code with simulation kernel and one of the user interfaces provided, command line (batch) and interactive, graphical. 6 • Simulation results are written into output vector and scalar files. the Analysis Tool used to visualize them. Result files are text- based, so it could processed with R, Matlab or other tools.
  • 7. 7/20 Build OMNeT++ Project (1/2) › 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
  • 8. 8/20 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
  • 9. 9/20 AODV Network Simulator (1/4) › We will generate an Ad-Hoc Network contains variable number of hosts (100,150,250,350,450,500) host . › In all Scenarios, node number 0 will send packages to the fixed node › We will measure the End-To-End Delay for first 700 packet arrives to the fixed host › The source and destination at the same for all scenarios
  • 10. 10/20 AODV Network Simulator (2/4) › Network Description file (ned) – Add reference to network components › import inet.nodes.inet.AdhocHost; › import inet.networklayer.autorouting.ipv4.IPv4NetworkConfigurator; › import inet.world.radio.ChannelControl; – Network Parameters › int numHosts; // in our presentation will be (100,150,250,350,450,500) › int numFixHosts;//in our presenatation will be 1 › connections allowunconnected: – components Parameters (submodules) › fixhost[numFixHosts]: AdhocHost › host[numHosts]: AdhocHost › channelControl: ChannelControl › configurator: IPv4NetworkConfigurator – interface hosts='*' address='145.236.x.x' netmask='255.255.0.0'
  • 11. 11/20 AODV Network Simulator (3/4) › Initialization file (ini) › [General] › network = test3 › description = "Aodv Simple test“ › **.routingProtocol = "AODVUU“ › *.numFixHosts = 1 › *.numHosts = 3 › **.arp.globalARP = true
