How to Start Proactive Protocols Projects using OMNeT++

To stimulate a project, we replicate the proactive routing protocols using OMNeT++ has includes the planning and executing or extending a protocol which handles the up-to-date routing tables, even when no congestion for exists. Sample of proactive protocols has involves the OSPF (Open Shortest Path First), DSDV (Destination-Sequenced Distance-Vector Routing), and Babel. Here’s a structured guide:

Steps to Start Proactive Protocols Projects using OMNeT++

  1. Understand Proactive Protocols
  • Definition: The proactive protocols are continuously computing routes for all available destinations and handling the routing tables.
  • Examples:
    • OSPF: Link-state protocol used their Dijkstra’s technique.
    • DSDV: Distance-vector protocol through periodic updates.
    • Babel: Distance-vector protocol supporting IPv4 and IPv6.
  • Advantages:
    • The Low latency for route discovery.
  • Challenges:
    • High control overhead in large networks.
  1. Set Up OMNeT++ Environment
  • Install OMNeT++: Download and install OMNeT++.
  • Install INET Framework: INET has involves the execution for proactive protocols such as OSPF. Create and integrate it:

git clone https://github.com/inet-framework/inet.git

cd inet

make

  1. Explore Existing Proactive Implementations
  • INET: Checked the INET’s routing modules for previous the proactive protocols such as OSPF.
  • Extensions: If necessary, the protocol is not possible, used a similar protocol such as OSPF a template we build your execution.
  1. Plan the Project
  • Define Objectives:
    • Replicate a proactive protocol such as OSPF or DSDV.
    • Study the performance below the various network environment.
  • Metrics to Analyze:
    • Routing overhead.
    • Convergence time.
    • Packet delivery ratio.
    • End-to-end delay.
  • Network Topology:
    • Simple: A small grid or mesh network for initial validation is a simple.
    • Complex: Scalable networks we validate the performance and efficiency.
  1. Design the Simulation
  • Topology:
    • Used a network of routers or nodes in a .ned file.
    • Sample:

network ProactiveNetwork

{

submodules:

router1: Router;

router2: Router;

router3: Router;

connections:

router1.ethg++ <–> router2.ethg++;

router2.ethg++ <–> router3.ethg++;

}

  • Traffic:
    • Build traffic using UDP or TCP applications we replicate the data flow.
    • Improve the background congestion we follow the protocol behaviour below load.
  1. Implement or Configure the Protocol
  • OSPF (INET):
    • Setting the OSPF in the .ini file:

*.router[*].ospf.routerId = “192.168.1.1”

*.router[*].ospf.areaId = “0.0.0.0”

*.router[*].ospf.interfaces[*].helloInterval = 10s

*.router[*].ospf.interfaces[*].deadInterval = 40s

  • Custom Protocol Implementation:
    • Routing Table: Execute a routing table structure we store all destinations.
    • Periodic Updates:
      • For link-state: Modify the Link-State Advertisements (LSAs).
      • For distance-vector: Alter the periodic bring up-to-date with hop counts.
    • Algorithm:
      • Used the Dijkstra’s algorithm for link-state protocols.
      • Use the Bellman-Ford for distance-vector protocols.
  1. Simulate and Test
  • Scenarios:
    • Static topology: Assure the routes are correctly computed and distributed.
    • Dynamic topology: Validate the connection failures and recoveries.
  • Validation:
    • Test the routing tables at every node.
    • Checked the packets are routed correctly according to the protocol.
  • Performance Metrics:
    • Calculated the convergence time later a topology modification.
    • Assign the routing overhead due we control the communication.
  1. Analyze Results
  • Used the outcomes the OMNeT++’s built-in tools or export logs for analysis in external tools such as Python, MATLAB.
  • Metrics:
    • Control overhead.
    • End-to-end delay.
    • Packet delivery ratio.
    • Convergence time.
  1. Extend the Project
  • QoS Enhancements:
    • Enhance the support for differentiated services such as prioritizing certain traffic.
  • Energy Efficiency:
    • Replicate the proactive protocols in energy-constrained networks such as IoT.
  • Security:
    • Execute the mechanisms we ensure the routing updates such as cryptographic authentication.

Example: Simulating OSPF in INET

  1. Create the Topology:
    • Descirbe a network of routers in a NED file.
    • Example:

network OSPFNetwork

{

submodules:

router1: Router;

router2: Router;

router3: Router;

connections:

router1.ethg++ <–> router2.ethg++;

router2.ethg++ <–> router3.ethg++;

}

  1. Configure the Protocol:
    • Ensure the OSPF in the .ini file.

*.router[*].ospf.enabled = true

*.router[*].ospf.routerId = “192.168.1.1”

*.router[*].ospf.areaId = “0.0.0.0”

  1. Document and Report
  • Protocol Description: Describe on how the protocol works.
  • Simulation Setup: State the topology for configuration and traffic.
  • Results: Present the parameter metrics such as delay, overhead, and delivery ratio.
  • Conclusion: Emphasize the insights for possible improvements.
