How to Start AOMDV Protocol Projects Using OMNeT++

To start an Ad hoc On-demand Multipath Distance Vector (AOMDV) protocol project in OMNeT++, we adhere to these steps. AOMDV is an augmentation AODV of to offer numerous paths among the source and destination enhancing the route reliability and minimizing network overhead.

Steps to Start AOMDV Protocol Projects in OMNeT++

  1. Understand AOMDV Basics
  • What is AOMDV?
    • AOMDV determines and sustains several loop-free and link-disjoint paths per destination.
    • Multipath routing offers redundancy to enhance the fault tolerance and load balancing.
  • Key Features:
    • Route discovery and maintenance same to AODV however it assist for numerous paths.
    • It minimises the occurrence of route discoveries with the help of alternate paths once the main path flops.
  1. Set Up OMNeT++
  • Download and Install:
    • Download and install the new version of OMNeT++ on the system.
  • Install INET Framework:
    • INET framework offers a base for executing the routing protocols.
    • Download and set INET framework within OMNeT++.
  1. Define Project Objectives
  • What to Simulate?
    • Multipath behavior of AOMDV and their influence over network performance.
    • We need to equate the AOMDV including other routing protocols like AODV, DSR.
  • Metrics to Analyze:
    • Path reliability.
    • End-to-end delay.
    • Routing overhead.
    • Packet delivery ratio.
  1. Create a New OMNeT++ Project
  • Steps:
    1. Go to OMNeT++ IDE.
    2. Make a new project using File > New > OMNeT++ Project.
    3. Name it as AOMDV_Simulation.
  1. Design the Network Topology
  • Network Design:
    • Create a topology including moveable or static nodes.
    • Make use of wireless communication links.
  • Example .ned File:

network AOMDVNetwork

{

submodules:

node[20]: WirelessHost;

connections allowunconnected:

node[*].wlan <–> node[*].wlan;

}

  1. Configure AOMDV Protocol
  • Using INET’s AODV as a Base:
    • INET framework has AODV that can be prolonged to execute the AOMDV.
    •  Clone and change the AODV execution to make a custom module that supports to:
      • Several route tables.
      • Route discovery and maintenance for multipath.
    • Utilise omnetpp.ini, modernise the configuration:

network = AOMDVNetwork

*.node[*].routingProtocol = “AOMDV”

*.node[*].mobilityModel = “inet.mobility.single.RandomWaypointMobility”

  1. Implement AOMDV Logic
  • Route Discovery:
    • We need to alter the route discovery mechanism of AODV to find several paths.
    • Determine and establish numerous disjoint paths with the support of RREQ and RREP messages.
  • Route Maintenance:
    • Mange the link failures by changing to another paths.
    • When every path flop then transmits RERR (Route Error) messages.
  • Path Selection:
    • Execute a path selection mechanism to give precedence paths depends on the parameters such as hop count, latency, or reliability.
  • Neighbor Discovery:
    • For every node sustain a neighbor table.
  1. Add Traffic Models
  • Traffic Generation:
    • Make use of TCP or UDP replicating the data traffic among nodes.
    • Instance of UDP:

*.node[0].app[0].typename = “UdpBasicApp”

*.node[0].app[0].destAddress = “node[15]”

*.node[0].app[0].destPort = 5000

  1. Run Simulations
  • Compile the Project:
    • Compile the project to make sure that execution contains not any errors.
  • Execute the Simulation:
    • Execute the simulation and also monitor how AOMDV determines and sustains several paths.
  • Monitor Metrics:
    • Seize routing parameters such as RREQ count, RREP latency, and routing table updates to utilize logging tools of OMNeT++.
  1. Analyze Results
  • Key Metrics:
    • Packet Delivery Ratio: We need to estimate the rate of effective delivered packets.
    • End-to-End Delay: Measure the average duration attaining its destination for packets.
    • Routing Overhead: Calculate the volume of control packets that are created.
    • Path Utilization: Assess frequency of alternate path utilization.
  • Visualization:
    • Observe the node movement, message exchanges, and path changes to leverage the simulation visualizer of OMNeT++.
  1. Optimize and Experiment
  • Experimentation:
    • Diverse network metrics like node density, mobility speed, and traffic load.
  • Optimization:
    • Adapt AOMDV indicators such as path selection criteria or route timeout intervals for optimization.
  1. Extend the Project
  • QoS Support:
    • Integrate the QoS-aware routing to give precedence of paths depends on the metrics like bandwidth or latency.
  • Energy Efficiency:
    • Launch energy-aware routing to extend the network lifetime for power efficiency.
  • Security:
    • We need to execute the protection mechanisms versus attacks such as route falsification or Blackhole attacks for network security.
