How to Start 5G Network Slicing Projects Using NS3

To start the network slicing using NS3 which is a 5G’s core aspect to permit diverse virtual networks to be made at the similar physical infrastructure providing to distinct use cases such as IoT, enhanced mobile broadband, and ultra-reliable low-latency interactions. We follow below given steps to start a 5G network slicing project using NS3:

Steps to Start 5G Network Slicing Projects in NS3

Step 1: Set Up NS3 Environment

  1. Download and Install NS3:
    • From the official site, we download the new version of NS3.
    • Install needed dependencies and based on the operating system, we configure NS3.
  2. Install Network Slicing Modules (Optional):
    • Some custom modules have network slicing within NS3. Try to find open-source 5G modules or extensions if available for NS3.

Step 2: Familiarize Yourself with NS3 Basics

  1. Learn Basic NS3 Simulation Techniques:
    • We have much knowledge about describe the nodes, devices, applications, and channels in NS3.
  2. Explore 4G LTE and EPC Modules:
    • NS3 offers an LTE module including an EPC (Evolved Packet Core) network. To know, it will support to create and replicate the 5G networks as it distributes same concepts of EPC.

Step 3: Define Network Slicing Requirements

  1. Identify the Slices:
    • Depends on the service type, we describe diverse slices. For instance, eMBB (enhanced Mobile Broadband), URLLC (Ultra-Reliable Low-Latency Communications), or mMTC (massive Machine-Type Communications).
  2. Allocate Resources per Slice:
    • Every single slice must contain their bandwidth, latency, and reliability requirements. Find out the resource allocation strategies depends on these needs.

Step 4: Create Virtualized Networks for Each Slice

  1. Set Up Virtual Network Environments:
    • Make separate logical networks or set up virtual networks by means of allocating diverse IP subnets, applications, and quality-of-service (QoS) policies for each slice in NS3.
  2. Configure QoS for Slices:
    • Configure diverse traffic priorities and resource allocations for each slice utilizing NS-3’s QoS capabilities. For example, low-latency, high-reliability settings for URLLC, and higher bandwidth for eMBB.

Step 5: Implement Network Slicing

  1. Custom Slicing Policy Enforcement:
    • Handle the resource allocation according to the slicing policies to utilize NS3’s scheduling algorithms or make a custom scheduler. For instance, create a scheduler to assign the resources actively based on the real-time demands among slices.
  2. Use EPC Network to Connect Slices to Core Network:
    • Incorporate data path of each slice via the EPC (for LTE/5G core network integration) and then replicate the interconnections including diverse backhaul and core network sets up.

Step 6: Performance Evaluation

  1. Run Simulations and Collect Data:
    • Execute different traffic situations to measure depends on their certain needs how each slice executes.
  2. Analyze Results:
    • Assess throughput, latency, and reliability for each slice. We can examine the resource allocation efficiency, slice isolation, and overall network performance.

Step 7: Optimization and Future Expansion

  1. Optimize Slicing Policies:
    • Change the slicing algorithms or policies, according to simulation outcomes to enhance the performance.
  2. Experiment with New Use Cases:
    • Discover new 5G use cases or more slices by modifying NS3 sets up and resource allocation policies.
