How to Start Mesh Protocols Projects using OMNeT++

To stimulate a Mesh Protocol project using OMNeT++ typically has includes the replicating for wireless mesh networks in which nodes perform as the both clients and routers. A popular protocol for mesh networks is HWMP (Hybrid Wireless Mesh Protocol), part of the IEEE 802.11s standard. Here’s how to set up a project for the implementation:

Steps to Start Mesh Protocols Projects using OMNeT++

1. Understand Mesh Protocols

• What are Mesh Protocols?
  • Protocols are ensuring the multi-hop communication in wireless networks.
  • Every node can be the relay congestion for generating a resilient and dynamic network.
• Examples:
  • HWMP (Hybrid Wireless Mesh Protocol): Associates for the proactive and reactive routing.
  • OLSR (Optimized Link State Routing): It is a proactive routing protocol.
  • BATMAN (Better Approach to Mobile Ad hoc Networking): A distributed protocol for the wireless mesh networks.

2. Set Up OMNeT++

• Install OMNeT++:
  • Download OMNeT++ and set it up.
  • Validate the installation by sample replication.
• Install INET Framework:
  • Download INET from the INET GitHub repository.
  • We compile and integrate the INET through OMNeT++.

3. Create a New Project

• Open OMNeT++ IDE.
• Create a New OMNeT++ Project:
  • Go to File > New > OMNeT++ Project.
  • Name the project such as MeshProtocolProject.
• Link the project to the INET framework:
  • Right-click the project, select Properties > Project References, and check INET.

4. Design the Mesh Network

• Create a .ned file to define the mesh network topology:

network MeshNetwork {

submodules:

meshNode1: WirelessHost {

@display(“p=100,100”);

}

meshNode2: WirelessHost {

@display(“p=200,200”);

}

meshNode3: WirelessHost {

@display(“p=300,300”);

}

meshNode4: WirelessHost {

@display(“p=200,300”);

}

connections allowunconnected:

meshNode1.wlanRadio++ <–> meshNode2.wlanRadio++;

meshNode2.wlanRadio++ <–> meshNode3.wlanRadio++;

meshNode3.wlanRadio++ <–> meshNode4.wlanRadio++;

}

}

5. Configure the Mesh Protocol

• Ensure the HWMP or another mesh protocol in the INET framework:
  • Edit the omnetpp.ini file:

[General]

network = MeshNetwork

sim-time-limit = 100s

*.meshNode*.wlan.macType = “Ie80211Mesh”

*.meshNode*.wlan.routingTable = “Hwmp” # Use HWMP for mesh routing

*.meshNode*.mobility.mobilityType = “StationaryMobility” # Use mobility if needed

• For mobility:

*.meshNode*.mobility.mobilityType = “RandomWaypointMobility”

*.meshNode*.mobility.speed = uniform(1mps, 10mps)

6. Simulate and Observe

• Run the Simulation:
  • Establish the replication of we track on how the mesh nodes discover and handles the routes.
  • Follow on the route discovery (proactive/reactive), message delivery, and resilience to node failures.
• Debugging:
  • Ensure the logging for routing and communication activities:

*.meshNode*.verbose = true

7. Analyze Performance

• Metrics to Evaluate:
  • End-to-end delay.
  • Packet delivery ratio (PDR).
  • Throughput.
  • Routing overhead.
• Used the OMNeT++’s analysis tools or export data for advanced analysis in Python or MATLAB.

8. Extend the Project

• Add Features:
  • QoS-aware routing.
  • Energy-efficient mesh routing.
  • Secure routing for resilience against attacks.
• Test Scenarios:
  • The node mobility and dynamic topology changes are the validate environment.
  • Replicate the failures and we validate the network resilience.
  • Improve the congestion design we replicate the real-world of applications such as video streaming or IoT data.

9. Document and Present

• Document the replication configuration, objectives, and outcomes.
• Build a visual for sample topology graphs, performance charts we showcase the protocol performance.
