To simulate the Dynamic MANET On-demand (DYMO) protocol using OPNET, we need to contain configuring a mobile ad hoc network (MANET) in which nodes determine routes on-demand instead of sustaining entire routing tables continuously. DYMO is an expansion of AODV and is created to enhance the routing efficiency by only launching routes when required. Here’s a general approach on how to simulate DYMO in OPNET:
Steps to Simulate DYMO Protocol Projects in OPNET
- Initialize the Project and Define Network Topology
- Create a New Project: Initially, we make a new project within OPNET and choosing a MANET set up to signify a network of mobile nodes.
- Define the Simulation Area: Configure the simulation area to match the situation like urban area or open field. DYMO executes successfully in dynamic, mobile environments, thus the area would permit for node movement.
- Add and Configure Mobile Nodes
- Place Mobile Nodes: Insert the mobile nodes through the simulation area to make a multi-hop network. The amount of nodes would be adequate to experiment the DYMO’s routing abilities and responsiveness to modifications.
- Assign Mobility Models: Allocate the mobility model to every node like Random Waypoint or Manhattan Grid, based on the situation. Configure parameters such as speed and pause time to replicate the realistic node movement.
- Enable DYMO Protocol on Nodes
- Install DYMO Protocol: If DYMO is obtainable in the OPNET library then set up every node to utilize DYMO like its routing protocol. DYMO launches routes on-demand via route request (RREQ) and route reply (RREP) messages.
- Configure DYMO Parameters:
- Route Timeout: Configure the route lifetime or timeout for DYMO routes, to describe how long a route stays valid after it is launched.
- Hello Interval (Optional): Even though DYMO does not need periodic hello messages, we can felicitate them to enhance the route accuracy within highly dynamic networks.
- Route Maintenance: Facilitate route maintenance mechanisms so as to DYMO can identify the broken links and start route repair when required.
- Define Traffic Models
- Application Traffic: Configure traffic flows, which replicate the data transfer, using normal applications such as VoIP, FTP, or Video Streaming.
- Traffic Patterns: Indicate source and destination sets to make a combination of short- and long-distance interaction. Examining both kinds of flows will support to estimate the capability of DYMO to launch routes over diverse distances.
- Simulation Parameters and Scenarios
- Set Simulation Duration: Configure an adequate simulation time to monitor the DYMO’s route discovery, route maintenance, and packet delivery performance.
- Create Multiple Scenarios:
- High Mobility vs. Low Mobility: Change node speeds to experiment the efficiency of DYMO in both stable and highly dynamic networks.
- Network Density: Modify the number of nodes to observe how DYMO scrambles in dense and sparse networks.
- Fault Tolerance: Mimic arbitrary link or node failures to monitor how DYMO adjusts and re-establishes routes once existing paths break.
- Define Performance Metrics and Data Collection
- Key Metrics for DYMO:
- Packet Delivery Ratio: Estimates the percentage of well delivered packets, which showing DYMO’s routing reliability.
- End-to-End Delay: Monitors the duration for packets to move from source to destination that deliberating DYMO’s routing efficiency.
- Routing Overhead: Estimates the control packets are made by DYMO for route discovery and maintenance.
- Route Discovery Time: Monitors the time DYMO takes to determine a route to the destination after launching a route request.
- Route Repair Time: Observes the time it takes DYMO to re-establish routes after identifying a broken link.
- Data Collection Setup: Record these metrics, that concentrating on packet delivery, delay, routing overhead, and route stability to estimate the performance of DYMO using OPNET’s data collection tools.
- Run the Simulation and Analyze Results
- Execute the Simulation: Execute the simulation and then monitor DYMO’s performance, which especially how it manages on-demand route discovery and maintenance within dynamic conditions.
- Analyze Results: Make plots for packet delivery ratio, end-to-end delay, and routing overhead utilizing OPNET’s analysis tools. Analyse effectiveness of DYMO in route discovery and stability that particularly in response to network modifications.
