To simulate the Clusterhead Gateway Switch Routing (CGSR) protocol within OPNET, it has contains to make a mobile ad hoc network (MANET) in which nodes are arranged into clusters, every cluster with a designated clusterhead, which handles routing in and among the clusters. CGSR is a hierarchical protocol that intends it depends on the clusterheads to enable interaction that supporting to handle the network scalability and efficiency. Given below is a step-by-step guide to replicating CGSR in OPNET:
Steps to Simulate CGSR Protocol Projects in OPNET
- Initialize the Project and Network Topology
- Create a New Project: Initially, we make a new project within OPNET and choosing a MANET environment to denote a network of mobile nodes, which will be clustered.
- Define the Simulation Area: Configure a simulation area that appropriate for the network like an urban or rural layout, and find the range within which nodes can interact.
- Add and Configure Mobile Nodes
- Place Mobile Nodes: Insert numerous mobile nodes to function like devices in the MANET. The amount of nodes would be adequate to make several clusters.
- Assign Mobility Models: Replicate the realistic movement using mobility models such as Random Waypoint or Manhattan Grid. Set up speed and mobility metrics according to the intended environment such as slower speeds for pedestrian scenarios or higher speeds for vehicular situations.
- Enable CGSR Protocol on Nodes
- Configure CGSR Protocol: If CGSR is obtainable in the OPNET library then facilitate it on every node. In CGSR, nodes are arranged into clusters, along with a clusterhead responsible for routing and interaction management in the cluster.
- Clusterhead Selection and Assignment:
- CGSR utilizes a clusterhead selection process depends on the node IDs or another described metric. Set up the selection mechanism to allocate clusterheads between the nodes.
- Clusterheads will handle the intra-cluster routing and interaction with nearby clusterheads to enable inter-cluster routing.
- Gateway Node Configuration: Gateways are nodes which bridge interaction among clusters. Set up gateways if obtainable in the configuration then permitting them to send data through clusters.
- Define Traffic Models
- Application Traffic: Describe the traffic patterns among nodes to replicate the real-world interaction. Normal applications comprise of VoIP, File Transfer Protocol (FTP), or Video Streaming.
- Traffic Patterns: Configure diverse traffic flows between nodes in the similar cluster and over diverse clusters. This set up will support to estimate the performance of CGSR in handling the intra-cluster and inter-cluster communication.
- Simulation Parameters and Scenarios
- Simulation Duration: Configure the simulation time to permit for numerous updates within clusterhead selection and interaction stability.
- Create Multiple Scenarios: Experiment CGSR performance under multiple conditions:
- Alter node mobility and speed to estimate the capability of CGSR to handle the clusters in dynamic conditions.
- Modify node density to observe how CGSR executes with additional clusters and higher communication demands.
- Launch random node failures to monitor the CGSR’s resilience in sustaining cluster communication.
- Performance Metrics and Data Collection
- Key Metrics for CGSR:
- Packet Delivery Ratio: Evaluate the ratio of well delivered packets to total packets transmitted, which computing how CGSR handles the routing efficiency.
- End-to-End Delay: Monitor latency for data packets that offering insights into CGSR’s efficiency in handling interaction through clusters.
- Routing Overhead: For clusterhead selection and maintenance, CGSR makes control packets. Assess routing overhead to know the CGSR’s network load.
- Clusterhead and Gateway Load: Observe the load on clusterheads and gateway nodes to monitor how successfully CGSR delivers the routing responsibilities.
- Cluster Stability: Measure the frequency of cluster reconfigurations by reason of the node mobility or clusterhead changes.
- Data Collection Setup: Record these metrics that concentrating on packet delivery, routing overhead, and delay metrics utilizing OPNET’s data collection tools.
- Run the Simulation and Analyze Results
- Execute the Simulation: Execute the simulation that focused to how CGSR manages the routing within a clustered network and adjusts to modifications in topology.
- Analyze Results: Analyze the metrics gathered using OPNET’s analysis tools. Examine the cluster stability, packet delivery ratio, and routing overhead to know the efficiency of CGSR and scalability.
