To simulate Destination-Sequenced Distance Vector (DSDV) protocol projects using OPNET (Riverbed Modeler) we need to comprise to configure a network along with DSDV-enabled nodes, set up routing tables, and monitor the behavior of this proactive routing protocol within mobile ad hoc networks (MANETs). DSDV protocol is depends on the Bellman-Ford algorithm in which each node sustains a routing table including the shortest paths to every other node that periodically updated.

Below is a step-by-step instruction for replicating DSDV in OPNET:
Steps to Simulate DSDV Protocol Projects in OPNET
- Define the Project Objectives and Scope
- Identify the purpose of the DSDV simulation: General targets contain examining routing table updates, monitoring protocol performance under node mobility, learning convergence time, and then likening DSDV with other MANET protocols.
- Set performance metrics: Significant parameters for DSDV comprise convergence time, end-to-end delay, routing overhead, packet delivery ratio, and resource consumption.
- Create the Network Topology
- Design a mobile ad hoc network (MANET): Make a network of mobile nodes like laptops, smartphones, which interact without fixed infrastructure using OPNET’s graphical interface.
- Define node movement patterns: Configure mobility models such as Random Waypoint Model to replicate the nodes progressing around within a particular area. This replicates the dynamic topology normal of MANETs.
- Enable and Configure DSDV on Mobile Nodes
- Enable DSDV routing protocol:
- Choose every single mobile node and set up their routing protocol to DSDV.
- Configure DSDV parameters:
- Place the update interval for routing tables that commands how often nodes propagate its tables to neighbors. DSDV normally utilizes periodic updates like every 15-30 seconds.
- Configure sequence numbers: DSDV utilizes sequence numbers to prevent the stale routes and routing loops. Sequence numbers maximize with each new route update, which supporting nodes differentiate among newer and older routing data.
- Route advertisement settings: Modify metrics for entire and incremental updates. Full updates contain transmitting the whole routing table, even though incremental updates only include recently altered entries to minimize the overhead.
- Simulate Application Traffic
- Generate application-specific traffic: Make realistic data flows like voice, video, file transfer over the network utilizing OPNET’s traffic generators.
- Define traffic patterns: For the data flows, we can configure source and destination nodes that making certain that the traffic crosses numerous nodes, which enabling DSDV to handle the routes dynamically.
- Monitor Routing Table Updates and Protocol Behavior
- Track routing updates:
- Allow logging on each node to monitor routing table updates and the frequency of table advertisements.
- Observe how DSDV handles the routes that noticing the changes within route parameters such as hop count and sequence numbers as nodes transfer.
- Analyze protocol overhead:
- Monitor the overhead generated by periodic routing table transmits and sequence number modernizes, particularly in situations with high mobility.
- Simulate Network Events and Changes
- Node Mobility:
- Transfer nodes around the network making a dynamic topology and then monitor how DSDV manages route updates in response to modifications.
- Node Failures:
- Replicate node or link failures by switching off certain nodes or links to monitor how fastly DSDV redirects traffic and modernizes the routing tables.
- Network Scalability:
- Maximize the amount of nodes within the network to experiment the scalability of DSDV and the impact of larger routing tables on convergence time and overhead.
- Collect and Analyze Performance Metrics
- Convergence Time: Calculate how long it acquires for every node modernizing its routes and after a topology change attain a constant view of the network.
- Packet Delivery Ratio: Compute the ratio of effectively delivered packets to the total transmitted packets to estimate the protocol’s reliability.
- End-to-End Delay: Monitor the time it takes for packets to move from the source to the destination that deliberating the effect of route changes.
- Routing Overhead: Examine the additional bandwidth utilized by routing updates to estimate the effectiveness of DSDV within sustaining route data.
- Optimize DSDV Parameters (Optional)
- Adjust Update Intervals: Test with shorter or longer update intervals observing how they impact the convergence time, network stability, and routing overhead.
- Explore Full vs. Incremental Updates: Estimate the trade-offs among entire and incremental updates to balance network overhead and reaction to topology changes.
- Increase Node Mobility and Density: Experiment with extra rapid movement or maximized node density to examine the performance of DSDV under high mobility and traffic.
- Generate Reports and Document Findings
- Visualization: Make graphs and charts that displaying convergence time, packet delivery ratios, delay, and routing overhead with the help of OPNET’s data analysis tools.
- Summarize Observations: Record the strengths and restrictions of DSDV under several conditions that noticing areas in which protocol optimizations might enhance the performance.
