How to Start Network Projects using OMNeT++

To stimulate a Network Project using OMNeT++ has includes the designing and replicating transmission networks performance and potentially executing the custom protocols or network components. The OMNeT++ delivers a modular and extensible platform which could be modified the wide range of networking environment have including the wired, wireless, IoT, and mobile networks.

Here’s a step-by-step procedure listed below there:

Steps to Start Network Projects using OMNeT++

  1. Install OMNeT++
  • Download: Install the latest version of OMNeT++.
  • Install: Observe the installation process for your operating system such as Linux, Windows, or macOS.
  • Verify Installation: Open the OMNeT++ IDE we assure the installed correctly.
  1. Install a Networking Framework

Intended for network projects we need the frameworks that offers the network protocols mobility models and communication stack support:

Recommended Frameworks:

  1. INET Framework:
    • Designed for replicating the IP networks for wireless communication, mobility, and routing protocols.
    • Download the INET’s official page.
  2. SimuLTE (optional):
    • Used for the LTE/5G communication networks.
  3. Veins (optional):
    • Used for vehicular ad hoc networks (VANETs) with SUMO integration.

Installation Steps:

  1. Download the desired framework such as INET.
  2. Excerpt it into your OMNeT++ workspace.
  3. Import the project into OMNeT++ such as File > Import > Existing Projects.
  4. Generate the framework within OMNeT++ we assure the compatibility.
  1. Understand Your Network Project Goals

State the kinds of network we need the replication for there:

  • Wired Networks: The wired networks for Ethernet, MPLS, or backbone networks.
  • Wireless Networks: The wireless networks for Wi-Fi, cellular networks, or ad hoc networks.
  • IoT and Sensor Networks: Replicate the IoT and Sensor Networks for low-power devices and their interactions.
  • Custom Protocols: Model the custom protocol and test new routing, transport, or MAC protocols.
  1. Define the Network Topology

Use OMNeT++’s .ned files to define your network structure.

Example .ned File for a Basic Wired Network:

network BasicNetwork

{

submodules:

hostA: StandardHost;

hostB: StandardHost;

router: Router;

connections:

hostA.gate++ <–> router.gate++;

router.gate++ <–> hostB.gate++;

}

Example .ned File for a Wireless Network:

network WirelessNetwork

{

submodules:

accessPoint: AccessPoint;

mobileNode[0..4]: MobileNode; // Array of 5 mobile nodes

connections:

mobileNode[*].gate++ <–> accessPoint.gate++;

}

  1. Implement Network Logic
  • Traffic Generation: Utilized the implement of network logic for built-in or custom applications we create the network congestion.
  • Routing and Forwarding: Execute or setting the routing protocols such as OSPF, AODV, or custom algorithms.
  • Quality of Service (QoS): Replicate the network parameters metrices such as bandwidth, latency, and packet loss.

Example C++ Code for Custom Packet Forwarding:

void Router::handlePacket(Packet *pkt)

{

if (isForLocalHost(pkt))

{

processLocally(pkt);

}

else

{

forwardPacket(pkt);

}

}

  1. Configure the Simulation

Setting the replication of parameters metrices has including their traffic patterns, data rates, and replication of duration in the omnetpp.ini file.

Example Configuration for Wired Network:

[General]

network = BasicNetwork

sim-time-limit = 100s

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

*.hostA.app[0].destAddress = “hostB”

*.hostA.app[0].messageLength = 1024

*.hostA.app[0].sendInterval = 1s

Example Configuration for Wireless Network:

[General]

network = WirelessNetwork

sim-time-limit = 200s

*.mobileNode[*].mobilityType = “RandomWaypointMobility”

*.mobileNode[*].mobility.speed = uniform(1, 5)

*.accessPoint.transmissionPower = 20dBm

  1. Run and Debug the Simulation
  • Run Simulation:
    • Right-click on the process of omnetpp.ini file and choose Run As > OMNeT++ replication.
  • Debugging:
    • Used their debugging for OMNeT++’s log outputs animation GUI and debugging tools we observe the packet flows and node interactions.
  1. Analyze Results
  • Performance Metrics:
    • The performance metrices for throughput, latency, jitter, packet delivery ratio, etc.
  • Visualization:
    • Utilized the visualization for OMNeT++’s built-in tools to visualize. sca and .vec files.
    • Transfer the data we use the Python or MATLAB for advanced plotting and analysis.
  1. Enhance Your Project
  • Scalability: Maximum the number of nodes and follow on the performance under their load for scalability.
  • Energy Efficiency: Replicate the battery-constrained devices and optimize energy usage of efficiency.
  • Fault Tolerance: The fault tolerance establishes the node or connection failures and calculate the recovery.
  • Security: Execute the secure communication protocols or replicate the attacks such as DDoS, eavesdropping.
  1. Extend the Project with Advanced Features
  • Dynamic Topologies:
    • Utilized their mobility models we replicate the dynamic networks such as MANETs or VANETs.
  • Cross-Layer Optimization:
    • Research with interactions among the MAC, network, and transport layers.
  • Multi-Technology Integration:
    • Combined the wired and wireless components for hybrid network replications.

Example Use Cases for Network Projects

  1. Wired Network Performance:
    • Estimate the effect of routing protocols on latency and throughput.
  2. Wi-Fi Network Simulation:
    • Calculate the impacts of interference and channel utilization in dense Wi-Fi deployments.
  3. IoT Network Design:
    • Replicate the sensor nodes with energy constraints and limited bandwidth.
  4. 5G Network Features:
    • Used their 5G network communicate the SimuLTE to analyze ultra-reliable low-latency communication (URLLC).
  5. Vehicular Ad Hoc Networks (VANETs):
    • Associates the Veins and SUMO for traffic-aware transmission for VANETs.
