How to Start Route Access Protocol Projects using OMNeT++

To stimulate a Route Access Protocol (RAP) project using OMNeT++ has been including the multiple techniques, involves the configure the OMNeT++ environment, model for network topology, choosing or estimate the route access protocol, process the replication, and study the outcomes. Route access protocols typically concentrate on maintaining the permits to routes in the networking environment, and their execution could differ in depending on the context, like as in vehicular networks, ad hoc networks, or further traditional IP-based networks.

Below is a step-by-step guide to getting started with Route Access Protocol (RAP) projects in OMNeT++.

Steps to Start Route Access Protocol Projects using OMNeT++

  1. Install OMNeT++ and INET Framework

OMNeT++ is a discrete event replication of environment for modelling transmission the networks, and INET is complete a framework which extends the OMNeT++ through a wide range of networking protocols.

Installation Steps:

  • Download OMNeT++: Download and install OMNeT++ from the OMNeT++ website.
  • Download INET Framework: We can download and create the INET framework, that is vital for many network replications:

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

Follow the INET documentation to integrate it with OMNeT++.

  1. Create a New OMNeT++ Project

Once OMNeT++ and INET are installed:

  • Open the OMNeT++ IDE.
  • Go to File > New > OMNeT++ Project we build a new project.
  • Give your project a name for sample “RouteAccessProtocol”.
  • Improve the INET framework to your project such as if not already done during the project creation.
  1. Design the Network Topology (NED File)

In OMNeT++, we describe the network topology using NED files. This file states the modules such as routers, hosts, or vehicles on how they are interconnected.

Intended for a Route Access Protocol, we might have a basic topology in which the several routers or hosts communicate, and a routing protocol is responsible for handling the permits to several network routes.

Example NED File for a basic routing setup:

network RouteAccessNetwork

{

submodules:

router1: Router {

@display(“p=100,100”);

}

router2: Router {

@display(“p=200,100”);

}

router3: Router {

@display(“p=300,100”);

}

host1: Host {

@display(“p=100,200”);

}

host2: Host {

@display(“p=300,200”);

}

connections:

host1.eth[0] <–> router1.eth[0];

router1.eth[1] <–> router2.eth[0];

router2.eth[1] <–> router3.eth[0];

host2.eth[0] <–> router3.eth[1];

}

  • In this sample, three routers and two hosts are connected in a linear topology. The routers will process the Route Access Protocol that handling the route selection and access.
  1. Select or Implement a Route Access Protocol

Depending on the network environment, we can either choose an existing route access protocol or execute your own.

  • Standard Routing Protocols (like RIP, OSPF, or EIGRP): If we need to use a well-known as routing protocol we handle the route access, we can setting the one of these protocols using INET.
  • Custom Route Access Protocol: If we necessary to replicate a alter Route Access Protocol, you will require an execution for it. OMNeT++ assign you to build a modify protocols through applying the essential modules and message handling.

Example of Configuring OSPF in omnetpp.ini:

[General]

network = RouteAccessNetwork

sim-time-limit = 100s

**.router1.routingTableClass = “OSPF”

**.router2.routingTableClass = “OSPF”

**.router3.routingTableClass = “OSPF”

If you’re developing a custom Route Access Protocol:

  • Describe the new module for the protocol.
  • Execute the message kinds for routing table management and route selection logic.
  • Used the message handlers to bring up-to-date the routing tables and handle the access control for several routes.
  1. Implement the Route Access Protocol (RAP)

If we are developing a modify the RAP, we will require the execution of C++ in OMNeT++. Here’s how you can technique for this:

Create a Custom Protocol Module:

  1. Define the Module:
    • In the NED file, describe a module for your RAP.
    • For sample, we might describe a module such as RouteAccessProtocol or RouteAccessRouter.
  2. Implement the Logic:
    • Build a new class such as RouteAccessProtocol.
    • Execute the protocol logic, has including they are:
      • Route Discovery: The protocol should permit the discovering available routes in the network.
      • Route Access Management: Execute the logic for assigning or denying access to particular routes based on sure criteria such as bandwidth, link cost, traffic load.
      • Routing Table: The protocol should have handled a routing table for every node that covers the routes possible for transmitting the packets.

Example structure of a custom routing protocol module (simplified):

class RouteAccessProtocol : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

virtual void processRoutingUpdate(cMessage *msg);

virtual void handleRouteAccessRequest(cMessage *msg);

};

  • Routing Updates: Run the bring up-to-date from neighbouring nodes to keep follow on the network topology.
  • Route Access Request: Maintain a message for requesting the access to a specific route such as a node asking for permission to use a route.

Example of Message Definition:

class RouteAccessRequest : public cMessage

{

public:

int requestedRoute;

bool accessGranted;

};

  • When a node transmits a RouteAccessRequest, the receiving node will process it, checked the route accessibility, and choose whether to grant or deny access.
  1. Configure Routing Parameters in omnetpp.ini

Next executing the routing protocol, setting it in the omnetpp.ini file. This involves the specifying that routers use your alter Route Access Protocol and describing many relevant parameters.

Example:

[General]

network = RouteAccessNetwork

sim-time-limit = 100s

 

**.router1.routingProtocol = “RouteAccessProtocol”

**.router2.routingProtocol = “RouteAccessProtocol”

**.router3.routingProtocol = “RouteAccessProtocol”

  1. Add Mobility and Traffic (Optional)

If you are replicating a mobile network such as for VANETs, we can improve the mobility and traffic. You can use the SUMO integration for realistic vehicle movement such as if replicating vehicular networks or set up a mobility for mobile nodes in another network environment.

For traffic generation, we can describe the Application Layer protocols such as FTP, HTTP, or Constant Bit Rate (CBR) congestion in your setting file.

  1. Run the Simulation

Next configure the network for routing protocol and mobility, we can start the replication:

  • Click Run in OMNeT++.
  • OMNeT++ will estimate the replication, and we can show the network activity, packet flows, and routing table modification.
  1. Analyze Results

OMNeT++ offers the complete replication of outcomes, like as scalar results, vector results, and animation of packet flows.

  • Use OMNeT++’s result analysis tools we study the performance metrics like as:
    • Packet Delivery Ratio (PDR)
    • Route Access Efficiency such as how effectively the protocol manages route access.
    • Network Throughput
    • Routing Convergence Time

Example to output results in omnetpp.ini:

[General]

output-scalar-file = “route_access_results.sca”

output-vector-file = “route_access_results.vec”

  1. Extend and Experiment
  • Test with Different Network Sizes: Scale the network through improving the further nodes to validate the protocol’s scalability.
  • Test with Different Topologies: Research through several network topologies such as star, mesh we show on how your route access protocol performs.
  • Compare with Other Routing Protocols: If your protocol is a variant of a previous protocol, compared its performance through the standard protocols such as RIP, OSPF, or AODV.

Resources:

  • OMNeT++ Documentation: OMNeT++ Docs
  • INET Framework Documentation: INET Docs
  • Custom Protocols in OMNeT++: OMNeT++ Custom Modules

By following these steps, you can create a Route Access Protocol (RAP) simulation in OMNeT++, whether you’re using an existing protocol like OSPF or developing a custom protocol from scratch.
