How to Start Reactive Protocol Projects using OMNeT++

To stimulate a Reactive Protocol project using OMNeT++, follow this structured procedure. Reactive routing protocols, like as AODV (Ad hoc On-demand Distance Vector) and DSR (Dynamic Source Routing), operate through determining the routes only when required for creating them ideal for dynamic networks such as MANETs.

Steps to Start Reactive Protocol Projects using OMNeT++

  1. Understand Reactive Protocols
  • Definition:
    • The reactive protocols build a route only after a source node initiates the transmission through a destination.
  • Key Features:
    • On-demand route discovery: Decrease the routing overhead.
    • Route Maintenance: Enable the routes remain test during the transmission.
  • Examples:
    • AODV, DSR, and TORA are generally used the reactive protocols.
  1. Install OMNeT++ and INET Framework
  • OMNeT++ Installation:
    • Download and install OMNeT++.
  • INET Framework:
    • INET models offers the execution of protocols and models for reactive routing.
    • Download the INET framework and setting the OMNeT++.
  1. Define Your Simulation Objectives
  • What to Simulate?
    • The Route discovery and maintenance in the reactive protocol.
    • The Performance below different environment such as mobility, congestion.
  • Metrics to Analyze:
    • End-to-end delay.
    • Packet delivery ratio (PDR).
    • Routing overhead.
  • Scenarios:
    • The Small networks are light congestion.
    • Large networks has includes the high mobility.
  1. Create a New OMNeT++ Project
  • Steps:
    1. Open OMNeT++ IDE.
    2. Create a new project: File > New > OMNeT++ Project.
    3. Name your project such as ReactiveProtocolSimulation.
  1. Set Up Network Topology
  • Define Nodes and Connections:
    • Build a .ned file we state the network:

network ReactiveProtocolNetwork

{

submodules:

node[10]: WirelessHost;

connections allowunconnected:

node[*].wlan <–> node[*].wlan;

}

  • Configure Wireless Nodes:
    • Used the setting of WirelessHost or a modify the node model.
  • Traffic Patterns:
    • Describe the congestion sources and destinations we trigger the route detection.
  1. Implement Reactive Protocol Logic
  • Using INET’s AODV or DSR:
    • INET offers the pre-implemented AODV and DSR models.
    • Ensure the AODV or DSR in the .ini file:

[Config ReactiveProtocol]

network = ReactiveProtocolNetwork

*.node[*].routingProtocol = “AODV”

*.node[*].mobility = “true”

  • Custom Implementation:
    • Encompass the previous INET models or generate the modify modules for other reactive protocols such as TORA or a novel protocol.
    • Implement:
      1. Route Discovery:
        • Transmit the route request (RREQ) communication.
        • Receive the route replies (RREP) we create a route.
      2. Route Maintenance:
        • Track the routes using error messages (RERR) for a maintenance.
      3. Route Deletion:
        • Eliminate the invalid routes when topology modify for route deletion.
  1. Configure Simulation Parameters
  • Mobility Models:
    • Used the INET’s mobility models such as RandomWaypointMobility to replicate the node transfer.
    • Example setting:

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

*.node[*].mobility.speed = uniform(5mps, 10mps)

  • Traffic Configuration:
    • Generate traffic between nodes using UDP or TCP applications:

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

*.node[0].app[0].destAddress = “node[5]”

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

*.node[0].app[0].startTime = uniform(0s, 10s)

  1. Run Simulations
  • Compile and Run:
    • Generate the project in OMNeT++ IDE.
    • Estimate the replication and follow on the node behaviour.
  • Visualize Results:
    • Used the outcomes for OMNeT++’s built-in visualization tools we follow on the RREQ and RREP messages.
  1. Analyze Performance
  • Key Metrics:
    • Latency: Time taken for packets we reach the destination for the latency.
    • Throughput: The throughput is total packets are delivered successfully.
    • Routing Overhead: Create a number of control packets.
  • Tools:
    • Used the OMNeT++’s vector and scalar tools we plot and study the performance metrics.
  1. Optimize and Experiment
  • Modify Parameters:
    • Research through node density for mobility patterns and traffic rates.
  • Introduce Faults:
    • Replicate the connection failures and track on the protocol behaviour during route rediscovery.
  • Optimize Protocols:
    • Execution the improvements such as:
      • It enhances the Energy-aware routing.
      • Select the QoS-aware route.
  1. Compare Reactive Protocols
  • Several protocols replicate such as AODV vs. DSR and associates their performance below the identical scenarios.
  1. Document Your Project
  • Include:
    • It starts the Objectives.
    • Then steps are involving they are network topology and parameters.
    • Next, Observations and results.
    • Finally, Recommendations for protocol improvements.

By following these steps, you can effectively develop and simulate a Reactive Protocol project using OMNeT++. If you need help with implementation or troubleshooting, feel free to ask!

We had successfully executed the Reactive Protocol that was executed using the tool of OMNeT++ that has to create the topology then apply the routing protocol and finally analyse the outcomes. Further guidance on this project will be included in a additional manual.
