To simulate Dynamic Source Routing (DSR) projects in OPNET, we can follow given steps. DSR is an on-demand routing protocol frequently utilized within mobile ad-hoc networks (MANETs) and DSR is recognised to actively determine routes for using source routing.
Steps to Simulate DSR Routing Projects in OPNET
- Set Up OPNET Environment
- To make a new project in OPNET Modeler. Configure the project and network name, select an appropriate scale, and describe the workspace attributes depends on the network environment we require to analyse.
- Design Network Topology
- DSR is normally utilized within MANET environments, thus configure a topology including mobile nodes like Mobile Nodes or Wireless LAN Workstations in OPNET.
- Locate the nodes based on a certain pattern or arbitrarily if the simulation contains constraints such as a grid or clustered distribution.
- Enable DSR as the Routing Protocol
- Choose every node, launch their IP layer set up then configure DSR like the routing protocol.
- In the IP Routing Parameters section and then from the list of routing protocols to choose DSR.
- Set up DSR-specific metrics like Route Discovery Timeout and Route Cache Size, if necessary. The default settings are commonly appropriate however adapting these can support to enhance the performance of DSR for certain network.
- Define Node Mobility
- DSR is created managing node mobility, thus configure mobility models experimenting the performance of DSR in dynamic conditions.
- Choose a mobility model such as Random Waypoint or Random Walk under the Mobility tab within the node’s characteristics. Set up speed, pause time, and other parameters describing movement patterns.
- Create Traffic Flows
- Describe source-destination pairs replicating data flow among nodes. For example:
- In Application Configuration, make a new application to choose a traffic type such as CBR (Constant Bit Rate) or Video Streaming.
- Configure certain source and destination nodes within the Profile Configuration managing in which the traffic flows.
- Configure Simulation Parameters
- Configure the simulation runtime, to describe a suitable length to seize every crucial routing dynamics.
- Accumulate information on performance parameters that concentrating on the DSR’s features, like:
- End-to-End Delay
- Packet Delivery Ratio
- Route Discovery Time
- Route Maintenance Events
- Route Cache Performance
- Run the Simulation
- Execute the replication monitoring how DSR manages route discovery and maintenance within a dynamic network.
- How packets are routed to utilize source routing, including full path discovered at the source and contained within packet headers indicated by OPNET.
- Analyze Results
- Compute the DSR’s performance utilizing OPNET’s analysis tools:
- Route Discovery Frequency: Indicates how frequently routes are determined when nodes travel.
- Packet Delivery Ratio: Deliberates the success rate of packets that are attaining its destination.
- End-to-End Delay: Estimates the latency through diverse routes.
- Route Cache Effectiveness: Assess the cached routes’ effectiveness in preventing repeated route discovery.
- Experiment with Different Scenarios
- Adapt node density, mobility patterns, and traffic load estimating the scalability and performance of DSR in different situations.
- We can experiment diverse values of DSR parameters such as cache timeout or maximum route length monitoring how they impact the network performance.
