To simulate the Ad-hoc On-demand Multipath Distance Vector (AOMDV) protocol within OPNET, we require configuring a mobile ad hoc network (MANET) in which nodes can determine several paths among a source and destination. AOMDV is an expansion of the AODV protocol, which determines and sustains numerous routes that offering better fault tolerance within dynamic networks. phdprime.com is the worlds premier research guidance company in providing tailored assistance for scholars , share with us all your project details we will give you immediate guidance and simulation results. Here’s a series of steps on how to replicate AOMDV in OPNET:
Steps to Simulate AOMDV Protocol Projects in OPNET
- Initialize the Project and Network Environment
- Create a New Project: We can open OPNET and create a new project that choosing a MANET set up to denote a network of mobile nodes.
- Define the Network Topology: Configure the simulation area such as an open field, urban layout in which nodes can travel freely. This environment will perform as the ad hoc network space.
- Add and Configure Mobile Nodes
- Place Mobile Nodes: Insert mobile nodes such as vehicles, drones, handheld devices to signify devices within the MANET. The amount of nodes would be adequate to experiment the route redundancy and AOMDV’s multipath capabilities.
- Configure Node Mobility: Allocate a mobility model like Random Waypoint or Manhattan Grid, based on the situation. Configure speed and pause time for realistic movement, since AOMDV depends on the mobility to experiment route reliability.
- Enable AOMDV Protocol on Nodes
- Install AOMDV Protocol: If AOMDV is obtainable in the OPNET library then set up every node to utilize the AOMDV by way of its routing protocol. AOMDV, such as AODV, uses route requests (RREQs) and route replies (RREPs) however sustains several routes for redundancy.
- Configure AOMDV Parameters:
- Route Request Frequency: For RREQ messages, modify the frequency and timeout interval.
- Route Expiry and Maintenance: Configure parameters for route expiration and maintenance to make sure that routes are refreshed for the reason that network topology modifications.
- Max Paths: Describe the maximum amount of multipath routes every node can save for an offered destination. It manages how several alternative paths AOMDV can sustain.
- Define Traffic Models
- Application Traffic: Make data traffic flows among nodes to replicate the real-world interaction. Instances contain FTP, HTTP, VoIP, or Video Streaming.
- Traffic Patterns: Describe numerous source-destination sets to experiment the capability of AOMDV to sustain many routes. Configure traffic patterns, which utilize long-distance routes through multiple hops that will create multipath routing beneficial.
- Simulation Parameters and Scenario Configuration
- Set Simulation Duration: Configure an adequate simulation time to monitor the behaviour of AOMDV under diverse conditions and to permit the time for route maintenance and multipath discovery.
- Create Multiple Scenarios: To estimate the efficiency of AOMDV, experiment diver situations:
- High Mobility vs. Low Mobility: Modify node speeds to see AOMDV’s route adaptation with changing mobility levels.
- Different Network Densities: Maximize the amount of nodes to experiment AOMDV’s scalability and multipath efficiency within dense networks.
- Node Failures and Link Breakages: Launch arbitrary node failures or link interruptions to estimate the AOMDV’s fault tolerance.
- Define Performance Metrics and Data Collection
- Key Metrics for AOMDV:
- Packet Delivery Ratio: Assess the percentage of packets effectively delivered to its destinations that showing route reliability.
- End-to-End Delay: Monitor latency from source to destination, which particularly with AOMDV’s multipath aspect.
- Routing Overhead: Observe the control messages like RREQs, RREPs, and route maintenance packets to estimate the network load.
- Route Discovery Time: Calculate the duration to determine numerous routes to a destination.
- Path Availability: Observe the availability of alternative paths that indicates how successfully AOMDV sustains multipath redundancy.
- Data Collection Setup: Set up OPNET to record these parameters along with a concentration on packet delivery, delay, routing overhead, and multipath effectiveness.
- Run the Simulation and Analyze Results
- Execute the Simulation: Execute the simulation, which monitoring AOMDV’s route discovery and maintenance processes that particularly how it determines and sustains numerous paths.
- Analyze Results: Make plots for the accumulated parameters like packet delivery ratio, end-to-end delay, and routing overhead. Examine AOMDV’s multipath usage and estimate their efficiency in sustaining reliable interaction.
Through this manual, we understood the project’s concepts and simulation methods for Ad-hoc On-demand Multipath Distance Vector (AOMDV) protocol, simulated and analysed in OPNET tool. Further insights will be added later.
