How to Simulate 5G Network Slicing Projects Using OPNET

To simulate 5G network slicing using OPNET that usually contains to create virtualized, separated network slices, which support diverse kinds of service requests, like improved Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and Massive Machine Type Communications (mMTC). Following is a step-by-step instruction to get started with 5G network slicing in OPNET:

Steps to Simulate 5G Network Slicing Projects in OPNET

1. Define the Network Slices

• Identify Slice Requirements: Find out the kind of slices we require replicating such as eMBB for high data rates, URLLC for low latency, mMTC for IoT.
• Assign Resources: Assign the network resources such as bandwidth, calculate power, and priority levels to each slice according to their requests.

2. Set Up Core Network and RAN (Radio Access Network)

• Core Network Setup: Set up the 5G core along with virtualized functions like the Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF). We can execute these like isolate modules within OPNET that simulating the 5G core functionalities.
• RAN Setup: Design the RAN with base stations or gNodeBs, which denoting distinct frequency bands or sets up for each slice. In OPNET, we can set up these nodes to denote the diverse performance parameters depend on its service type.

3. Implement Network Slicing Management

• Network Slice Management Function (NSMF): Configure a module within OPNET, which handles slice resources and distributes them based on the slice demands. We could replicate it by modifying the scheduling and priority within the OPNET process models.
• Slice Provisioning and Orchestration: Train the OPNET models to actively assign the resources according to the demand. Utilize parameters within OPNET’s simulation configuration to mechanize this process.

4. Configure Traffic Models for Each Slice

• Define Traffic Types: Make diverse traffic profiles within OPNET, like video streaming (eMBB), real-time control data (URLLC), and sensor data (mMTC).
• Apply Traffic to Slices: Apply every single traffic type to their respective network slice. Set up the packet arrival rate, packet size, and priority reflectinf the unique features of each slice’s traffic.

5. Run the Simulation

• Parameter Configuration: Configure the simulation parameters that contain duration, traffic intensity, and mobility patterns, to experiment the network slicing under numerous load conditions.
• Collect Metrics: Monitor key performance metrics such as latency, throughput, reliability, and resource utilization for every slice.

6. Analyze Results

• Performance Evaluation: Estimate the performance of each slice according to the predefined KPIs. For instance, make certain that URLLC slice converge latency requirements, and eMBB slice attains high throughput.
• Resource Allocation Efficiency: Examine how well resources were assigned to meets the each slice’s demands.

In this presentation encompasses an in-depth look at the sequential methodology for simulate the 5G Network Slicing projects and analyse its outcomes in OPNET with the option to delve deeper into specifies if required.
