To simulate Greedy Perimeter Stateless Routing (GPSR) protocol projects using OMNeT++, we can discover on how GPSR performs as a geographic routing protocol, using node positions for routing decisions. GPSR is usually utilized in mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs), where it selects paths according to proximity to the destination.
Here’s how to set up and simulate GPSR projects using OMNeT++:
Steps to Simulate GPSR Protocol Projects in OMNeT++
- Set up OMNeT++ and INET Framework
- Install OMNeT++: Make sure that we have the latest version installed.
- Install INET Framework: INET deliver basic support for wireless networking that can be expanded to execute GPSR by customizing routing modules to create forwarding decisions according to node positions.
- Configure Network Nodes for GPSR
- Wireless Nodes: Configure nodes as mobile wireless devices that will forward packets according to their geographic location relative to the destination.
- GPS Positioning: Permits the position data for each node. We can utilize the INET mobility modules to allocate coordinates and update positions by way of nodes move.
- Traffic Sources: Set up nodes to create traffic (e.g., UDP or TCP flows) to validate GPSR’s routing efficiency in dynamic topologies.
- Implement GPSR Mechanisms
- Greedy Forwarding: In GPSR, packets are forwarded to the neighbour closest to the destination. Set up nodes to estimate distances and choose the next hop according to this criterion.
- Perimeter Mode: When greedy forwarding fails that is no neighbor is closer to the destination, GPSR switches to perimeter mode using the right-hand rule to route around obstacles or network voids.
- Position Information: Make sure each node knows the positions of its neighbours that can be completed using periodic beacon messages to distribute location updates.
- Define Network Topology and Mobility Models
- Random Node Placement: Place nodes randomly within a chosen area to generate a wireless mesh network. This configures permits GPSR to illustrate its efficiency in non-uniform node distributions.
- Mobility Models: Utilize the Random Waypoint Mobility model or other mobility patterns to replicate node movement, monitoring how GPSR adjust to changes in node positions.
- Variable Node Density: Test with different node densities to measure GPSR’s performance in both sparse and dense networks.
- Simulate GPSR Protocol Operations
- Greedy Mode: Monitor on how packets are forwarded in greedy mode when a neighbour closer to the destination is obtainable.
- Switch to Perimeter Mode: Establish network voids or sparse areas in which greedy forwarding fails, imposing GPSR to utilize perimeter mode.
- Packet Delivery and Recovery: Monitor packet delivery success, specifically in cases in which GPSR must recover from routing around obstacles or re-entering greedy mode after perimeter traversal.
- Monitor and Collect Simulation Data
- Packet Delivery Ratio: Assess the percentage of successfully delivered packets to measure GPSR’s reliability in diverse network conditions.
- Hop Count and Path Efficiency: Record the number of hops per packet and relate the GPSR path to the enhance path to evaluate efficiency.
- Mode Switch Frequency: Monitor on how usually nodes switch among greedy and perimeter modes, reflecting GPSR’s adaptability to network topology changes.
- Analyse and Visualize Simulation Results
- Route Path Visualization: Utilize OMNeT++ visualization tools to display the paths taken by GPSR packets, important points in which the protocol switches from greedy to perimeter mode.
- Mobility Impact on Routing: envision node movement and how it impacts GPSR’s ability to sustain efficient routes to the destination.
- Perimeter Traversal Analysis: plot graphs illustrate the examples of perimeter traversal, supports to detect common obstacles or areas where GPSR’s greedy mode fails.
- Generate Reports and Graphs
- Packet Delivery Ratio Analysis: plot graphs illustrate the success rate of packet delivery via different mobility levels and network densities.
- Path Length vs. Optimal Path: Generate the average path length taken by GPSR compare to the shortest path, demonstrates GPSR’s routing efficiency in numerous conditions.
- Control Overhead: Evaluate the control message overhead such as beacons essential for position updates and relate it to the overall data traffic to measure GPSR’s scalability.
- Advanced Scenarios and Customization (Optional)
- Energy Consumption: If replicate energy-constrained nodes, monitor energy usage because of routing activities, especially in perimeter mode.
- Obstacles and Void Management: Establish obstacles or areas with low connectivity to challenge GPSR’s perimeter mode, discerning its performance in preventing routing loops and dead-ends.
- Performance Comparison with Other Protocols: Relate GPSR’s performance against other geographic or reactive protocols such as AODV or DSR to highlight its benefits and trade-offs.
