To simulate a flooding routing project within OPNET Modeler that need to contain setting up the network utilizing a flooding-based routing strategy in which each node sends incoming packets to every of their neighbors apart from which it obtained the packet. This method is simple however it can lead to network congestion, creating it appropriate for learning network reliability and performance in situations such as broadcast or highly redundant networks. We follow the below steps to configure a flooding routing simulation in OPNET:
Steps to Simulate Flooding Routing Projects in OPNET
- Set Up the OPNET Project
- To make a new project particularly for flooding routing in OPNET Modeler.
- Configure the workspace and then describe the simulation metrics like replication duration and parameters to seize according to the flooding behavior we require to examine.
- Design the Network Topology
- Make a network topology including several interconnected nodes such as routers, switches, clients, and servers.
- Associate nodes along with numerous links making a mesh or highly connected network structure that permits to monitor the flooding’s influence like packets propagate via the network.
- Contain source and destination nodes such as clients and servers to make and obtain traffic.
- Enable Flooding Routing Behavior
- As flooding is not a traditional routing protocol, we may require to manually set up every node to execute a flooding behavior:
- Inactivate any traditional routing protocols such as OSPF, RIP.
- Make a flooding mechanism utilizing custom routing scripts or OPNET’s Process Model editor:
- Describe a process in which each node sends incoming packets to its every neighbor apart from which it obtained the packet.
- For packets, execute a Time-to-Live (TTL) or hop limit to avoid the endless looping in the network.
- Contain a mechanism if we require to prevent the excessive redundancy to drop duplicate packets.
- Configure Link Characteristics and Network Metrics
- Describe the link metrics like bandwidth, delay, and error rates replicating realistic network conditions.
- If we need to learn the flooding influence on network performance then set up links along with changing capacities to monitor how flooding impacts of low-bandwidth or high-latency links.
- Add Application Traffic (Optional)
- Set up traffic among certain client and server nodes learning how flooding delivers packets in the network.
- Go to Application Config and Profile Config:
- Configure traffic patterns like file transfers or message exchanges, use the flooding method to make data, which will be sent.
- Link these profiles to client and server nodes to replicate the realistic interaction situations.
- Set Up Background Traffic for Congestion Analysis
- Replicate the network congestion, insert background traffic at certain links that permitting to monitor how flooding impacts the network performance in load.
- It will support to know how flooding communicates with other traffic types and their impact on network congestion.
- Configure Simulation Parameters for Flooding Metrics
- For parameters like packet delay, throughput, link utilization, and packet duplication to allow collection of metrics.
- For packet forwarding events and network-wide traffic analysis, permit logging to seize how packets distributes via the network in flooding.
- Run the Simulation
- Execute the replication then monitor the flooding routing’s performance like packets propagate via the network.
- Observe traffic through every node monitoring how flooding routing to makes redundancy, utilizes bandwidth, and spreads packets.
- Analyze Results
- Calculate the flooding-specific parameters utilizing OPNET’s analysis tools, after the simulation accomplishes:
- Packet Duplication Rate: Estimate the percentage of duplicate packets that are made by flooding and its influence over the network.
- Network Congestion: Verify link utilization to monitor the congestion on heavily utilized links and analyse how flooding impacts overall network bandwidth.
- Latency and Packet Delay: Examine the latency of packets to move via the network, particularly under high-traffic areas.
- Packet Delivery Ratio: Compute the ratio of packets effectively attaining its destination against packets are dropped or lost by reason of TTL expiry.
- Power Consumption (optional): If we are functioning on energy-constrained networks, such as sensor networks then examine the energy cost of flooding.
We followed the clear and structured method for replicating and analysing the Flooding Routing Projects utilizing OPNET. We are ready to deliver further, in-depth insights if necessary.
