How to start GPSR protocol projects using OMNeT++

To create a GPSR (Greedy Perimeter Stateless Routing) protocol project using OMNeT++, observe this structured step. GPSR is a geographic routing protocol for wireless networks for frequently used in MANETs (Mobile Ad-Hoc Networks) or WSNs (Wireless Sensor Networks). It uses an associate the greedy transmitting and perimeter routing when greedy transmitting fails.

Steps to start GPSR protocol projects using OMNeT++

  1. Understand GPSR Basics
  • What is GPSR?
    • The GPSR used a node positions for packet transmitting.
    • It has two modes:
      1. Greedy Forwarding: Transmit the packets for the neighbour to near the destination.
      2. Perimeter Forwarding: Used then greedy transmitting fails such as dead-end situation.
  • Key Features:
    • The Stateless for relying the neighbour tables.
    • It efficient for the dynamic networks.
  • Applications:
    • Applications has involved the Vehicular ad hoc networks (VANETs), WSNs, and MANETs.
  1. Install OMNeT++
  • Download and Install:
    • Install the latest version of OMNeT++.
  • Install INET Framework:
    • INET offers the foundation for wireless communication protocols and mobility models.
    • Download and configure the INET framework in OMNeT++.
  1. Define Project Objectives
  • What to Simulate?
    • Performance of GPSR in several network environments.
    • Associates the GPSR through other routing protocols such as AODV, DSR.
  • Metrics to Analyze:
    • End-to-end delay.
    • Packet delivery ratio.
    • Routing overhead.
  1. Create a New OMNeT++ Project
  • Steps:
    1. Open OMNeT++ IDE.
    2. Create a new project: File > New > OMNeT++ Project.
    3. Name the project such as GPSR_Simulation.
  1. Design the Network Topology
  • Network Design:
    • Involves the mobile nodes through position-awareness abilities.
    • Describe the nodes as wireless devices.
  • Example .ned File:

network GPSRNetwork

{

submodules:

node[20]: WirelessHost;

connections allowunconnected:

node[*].wlan <–> node[*].wlan;

}

  1. Configure GPSR Protocol
  • Enable GPSR:
    • The GPSR can be executed the INET or alter they modules.
    • If using INET, modify the configuration in omnetpp.ini:

[General]

network = GPSRNetwork

*.node[*].hasGPSR = true

*.node[*].gpsr.usePerimeterRouting = true

  • Custom Implementation:
    • Encompass the INET modules we involve the GPSR-specific logic:
      • Neighbour discovery.
      • Greedy forwarding.
      • Perimeter routing using planar graph traversal.
  1. Implement Mobility and Traffic Models
  • Mobility Models:
    • Use mobility to simulate dynamic environments:

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

*.node[*].mobility.speed = uniform(5mps, 15mps)

  • Traffic Patterns:
    • Configure traffic between nodes using UDP or TCP applications:

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

*.node[0].app[0].destAddress = “node[10]”

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

  1. Implement GPSR Logic
  • Neighbour Discovery:
    • Every node has handled the table of its immediate neighbours’ terms on periodic beaconing.
  • Greedy Forwarding:
    • The packets are forwarded to the neighbour near to the destination.
  • Perimeter Routing:
    • Used the planar graphs such as Gabriel Graph or Relative Neighbourhood Graph we traverse around voids then greedy transmitting the fails.
  • Failover Handling:
    • Execute the logic and we maintain the unreachable destinations or disconnections.
  1. Run Simulations
  • Compile and Execute:
    • Generate the project we assure there are no errors.
    • Process the replication of follow the packet flows and GPSR behaviour.
  • Monitor Metrics:
    • Used the follow on OMNeT++’s tools we seizure the scalar and vector results.
  1. Analyze Results
  • Performance Metrics:
    • Packet Delivery Ratio: Percentage of packets successfully delivered in the PDR.
    • End-to-End Delay: The Time taken for packets we reach the destination.
    • Routing Overhead: Number of control packets transmit the routing overhead.
  • Visualization:
    • Used the visualize for OMNeT++’s in the graphical tools we show the node movements and packet transmitting paths.
  1. Experiment and Optimize
  • Experiment:
    • Differ the network density of mobility and traffic load.
    • Establish the obstacles or dead zones to test perimeter routing.
  • Optimize GPSR:
    • Improve the neighbour discovery.
    • Enhance the QoS support for delay-sensitive applications.
  1. Extend the Project
  • Energy Efficiency:
    • Increase the power-aware routing to GPSR.
  • Security:
    • Execute the calculation of we avoid the GPSR vulnerabilities such as spoofing or misrouting.
  • Comparison:
    • Compared the GPSR through protocols such as AODV or DSR below the similar conditions.
