To Simulate Temporally-Ordered Routing Algorithm (TORA) projects in OPNET Modeler has contains to configure a network that supports reactive, on-demand routing for mobile ad hoc networks (MANETs). TORA is model to maintain frequent network topology variations and is specifically effective in increase their dynamic environments, in which it rapid creates and maintains routes in a distributed manner. Here’s a step-by-step procedure to replicate a TORA in OPNET:
Steps to Simulate Temporary Ordered Routing Projects using OPNET
- Set Up the OPNET Project
- Open OPNET Modeler we generate a new project specifically for TORA routing.
- State the project workspace it contains the replication parameters metrices such as replication duration and core parameter metrics such as route setup time, route maintenance, and packet delivery ratio.
- Design a Mobile Ad Hoc Network (MANET) Topology
- TORA is mainly utilized in mobile environments, as a result model a topology through mobile nodes that can communicate wirelessly.
- Builds s nodes in an arbitrary or grid layout inside a stated geographic range. Utilized a wireless connection to connect this node and assuring which in every other’s communication range.
- Setting a node with mobility models such as random waypoint or random direction to follow the TORA’s route adaptability as nodes transfer.
- Enable TORA Routing Protocol
- TORA performs by building a route only after needed and maintaining the routes so they’re required and in every mobile node’s properties ensure the TORA routing protocol for such as it is involved in your version of OPNET.
- Setting a TORA-specific parameter, such as:
- Route Maintenance Interval: These decides on how well often TORA bring up-to-date routes to adapt their topology changes.
- Link Reversal Mechanism: TORA utilized a connection reversal as a primary mechanism to creates and handles the routes in a loop-free manner. Enable these active for continuing stability through dynamic changes.
- If TORA is not natively accessible in OPNET version, we can require to builds a usage of routing process utilized the Process Model editor to simulate the TORA’s reactive and link-reversal mechanisms.
- Configure Link Characteristics
- Describe every link’s connection like as bandwidth, delay, and transmission range, for consistency wireless communication.
- Configure a various connection quality to validate TORA’s capability to handle and reroute traffic dynamically.
- Define Application Traffic
- Setting an application traffic to builds a data flows that TORA will route:
- In Application Config and Profile Config, explain application traffic kinds such as HTTP, FTP, VoIP to replicate their real data flow in the network.
- TORA to create a route and handles their connectivity as nodes transfer and assign their outlines to source and destination nodes to generate a continuous or recurrent data flows for forcing.
- Enable Metrics Collection for TORA Analysis
- Ensure the parameter metrics gathering for TORA-specific performance indicators, such as:
- Route Discovery Time: Calculate the duration TORA takes to create a routes on-demand.
- Route Maintenance and Failure Response: Follow on how TORA responds to connection breaks and re-introduce their connectivity utilized a connection reversal.
- Packet Delivery Ratio: The ratio of effectively delivered packets to the amount of transfer that has demonstrate the effectiveness of TORA’s routing.
- End-to-End Delay: Calculate their packet delay with routes to measure the effectiveness of TORA’s paths.
- Run the Simulation
- Initially the replication of track on how well TORA creates, handles, and tears down routes as needed.
- Follow on TORA’s link-reversal mechanism in activities when network topology changes for especially after nodes transfer out of every other’s area.
- Analyse Results
- Later the replication for done to utilized an OPNET’s investigation tools to estimate TORA’s performance:
- Route Setup Time and Discovery Efficiency: Calculate on how well quickly TORA creates a route later an initial route request for particularly in environments with frequent topology variations.
- Route Maintenance: Analyse their TORA’s ability to handle the routes of in spite of frequent connection failures and topology variations through following the frequency of route adjustments and reversals.
- Packet Delivery Ratio: Measure their packet delivery ratio to estimate TORA’s consistency in delivering packets to destinations.
- Latency and Route Stability: Follow on end-to-end delay and the stability of creates on routes and concentrating on how well stable TORA’s routes are over duration.
