      • Network offloading and resource sharing: Offload tasks to neighbouring nodes or edge servers to minimize the load at mobile devices.

Step 3: Set Up the Network Topology and Mobile Nodes

  1. Define Mobile Nodes:
    • In NS3, make nodes to signify the mobile devices such as smartphones, tablets.
    • Depends on the aim of project, set these nodes to utilize the Wi-Fi or LTE. For example, for local mobile networks utilise the Wi-Fi module or use LTE module for broader cellular connectivity.
  2. Set Up Access Points or Base Stations:
    • If utilizing Wi-Fi then make Wi-Fi access points associating the mobile nodes.
    • Configure LTE base stations (eNodeBs) to avoid connectivity to mobile nodes for cellular projects.
    • Set access points or base stations signifying the realistic coverage area.
  3. Configure the Network Topology:
    • Select a topology like a cellular network (with cells and handover zones) or an ad-hoc network (for peer-to-peer mobile communication).

Step 4: Configure Mobility Models

  1. Choose an Appropriate Mobility Model:
    • For replicating mobile nodes, NS3 offers numerous mobility models:
      • ConstantVelocityMobilityModel: For nodes to travel on a constant speed within a provided direction.
      • RandomWaypointMobilityModel: For random and free movement in which nodes travel to arbitrary destinations with pauses in among.
      • GaussMarkovMobilityModel: For more realistic movement including gradual modifications within speed and direction.
  2. Set Mobility Parameters:
    • Modify metrics such as speed, pause times, and movement boundaries to mat the situation of the project.
    • For instance, configure low speeds and restricted mobility in a pedestrian scenario. Configure higher speeds and predefined paths for a vehicular situation.

Step 5: Implement Network Applications and Data Transfer

  1. Configure Application Traffic:
    • Replicate diverse kinds of traffic to utilize NS3’s application layer:
      • UDP for low-latency, lightweight data transfer such as real-time video or IoT data.
      • For reliable data transfer, TCP is helpful for file sharing or data synchronization.
  2. Set Traffic Patterns:
    • According to the application requirements, we describe patterns:
      • Constant Bitrate (CBR) for streaming applications.
      • Burst Traffic for event-driven applications in which data is transmitted within bursts.

Step 6: Implement Key Mobile Computing Features

  1. Mobility and Handover Management:
    • NS3 have handover capabilities for cellular networks (LTE). Set metrics to observe how nodes sustain the connectivity whereas traveling among the base stations.
    • Experiment handover situations to estimate the latency and throughput like nodes transition among the access points or base stations.
  2. Resource Optimization:
    • For efficient use of resources, execute mechanisms. For example:
      • Adaptive Bandwidth Management: Alter bandwidth allocation actively depends on the node demand.
      • Energy-Saving Techniques: Launch sleeps cycles or power-saving modes replicating the battery management within mobile devices.
  3. Data Offloading and Edge Computing (Optional):
    • Replicate offloading tasks to neighbouring nodes, access points, or edge servers, minimizing load on mobile devices and to reduce latency.
    • Test with multi-access edge computing (MEC) in which nodes offload data executing to edge servers nearer to the mobile network.

Step 7: Define and Run Simulation Scenarios

  1. Create Different Scenarios:
    • Estimate the mobile computing configuration, to describe situations:
      • Static vs. Mobile Nodes: We equate the performance including stationary nodes and mobile nodes.
      • High-Density Setup: Replicate a dense network of nodes and then experiment for congestion and resource contention.
      • Dynamic Mobility and Handover: Analyse the situations in which nodes travel continuously and change among the access points or base stations.
  2. Define Application and Network Parameters:
    • Describe metrics like data rate, packet size, and interval for application traffic to equalize real-world applications.
    • Modify network metrics like link bandwidth and delay, to equalize the required environment such as urban area vs. open field.

Step 8: Collect and Analyze Performance Metrics

  1. Gather Simulation Data:
    • Gather simulation information to utilizing NS3’s tracing and logging tools:
      • Latency: The duration for data to move among the devices or to the server.
      • Throughput: The rate of effective data that can be sent.
      • Handover Delay: The delay experienced once switching among the access points or base stations.
      • Energy Consumption: If energy efficiency is a project objective, we estimate the energy used by nodes.
  2. Evaluate Network Performance:
