To start a drone-based Vehicular Ad Hoc Network (VANET) project using NS3 which enables to discover how drones can support vehicles by means of avoiding network coverage, data relaying, and prolonged connectivity. In VANETs, drones can work for diverse intentions like transmitting data, to improve interaction range, and offering support within emergencies. Following is a step-by-step method to configuring a drone-based VANET project using NS3.

Steps to Start Drone Based VANET Projects in NS3

Step 1: Set Up NS3 Environment

  1. Download and Install NS3:
    • From the official NS3 website, we download NS3 and install it including all essential dependencies.
    • Verify that NS3 is operating by executing an example programs such as wifi-simple-adhoc.cc.
  2. Enable Wi-Fi, Mobility, and Internet Modules:
    • For wireless communication, make sure that the Wi-Fi module is available, the Mobility module for vehicle and drone movement, and the Internet module for IP-based interaction among the nodes.
  3. Optional: Install SUMO for Realistic Vehicle Mobility:
    • SUMO (Simulation of Urban MObility) can be replicated the realistic vehicular mobility patterns and incorporate with NS3. SUMO offers realistic movement situations that are advantageous for VANET projects.

Step 2: Understand Key Components of Drone-based VANETs

  1. Vehicular Nodes:
    • Vehicles furnished with abilities of wireless interaction make the ground-based VANET. They interact with each other and along with drones overhead.
  2. Drone Nodes:
    • Drones (Unmanned Aerial Vehicles or UAVs) offer aerial support by means of prolonging coverage, to perform like relay nodes, or to gather data from remote areas.
  3. Communication Protocols:
    • VANETs generally utilize IEEE 802.11p (Dedicated Short-Range Communication, DSRC) or standard Wi-Fi protocols (IEEE 802.11a/b/g) for vehicle-to-vehicle (V2V) and vehicle-to-drone (V2D) interaction.
  4. Mobility Models:
    • Even though drones utilize the waypoint-based or grid-based models replicating flight patterns, vehicles frequently adhere to road-based or SUMO-generated mobility models.

Step 3: Define Project Objectives and Metrics

  1. Set Key Project Goals:
    • For drone-based VANET projects, crucial project objective contain:
      • Connectivity Enhancement: Prolong the network coverage and sustain connectivity to utilize drones in sparsely populated areas.
      • Data Relaying: Allow drones transmitting data among the detached vehicles.
      • Emergency Communication: It supports interaction for emergency messages within areas utilizing drones in which ground networks are obstructed or unavailable.
      • Latency Reduction: Employ drones to minimize the end-to-end delay by way of offering more interaction paths.
  2. Choose Relevant Metrics:
    • Key related parameters like latency, throughput, packet delivery ratio, drone coverage efficiency, and connectivity duration.

Step 4: Set Up Network Topology

  1. Define Vehicular and Drone Nodes:
    • Signify vehicles on the ground and drones in the air utilizing NS3 nodes. For enhanced connectivity, vehicles interact with each other and along with drones.
  2. Configure Wi-Fi Communication:
    • We can utilise WaveNetDevice for IEEE 802.11p (commonly used in VANETs) or for standard Wi-Fi interaction among the vehicles and drones to use WifiNetDevice.
    • Set Wi-Fi metrics like channel frequency, data rate, and transmission power to configure a reliable wireless interaction network.
  3. Set Up Mobility Models:
    • Vehicles: For basic movement, we utilize the NS3 Mobility module or incorporate with SUMO using realistic road-based movement patterns.
    • Drones: Utilize waypoint-based mobility models, such as WaypointMobilityModel, or for drone flight paths, custom mobility models like grid or patrol routes across the vehicular network.

Step 5: Configure IP Addressing and Routing

  1. Assign IP Addresses:
    • Designate IP addresses to every node to make sure those unique addresses for each vehicle and drone using Ipv4AddressHelper.
  2. Enable Ad Hoc Routing Protocols:
    • For ad hoc networks, we select a routing protocol suitable likeAODV (Ad hoc On-demand Distance Vector), DSDV (Destination-Sequenced Distance-Vector), or OLSR (Optimized Link State Routing).
    • These protocols allow active routing and multi-hop interaction among the vehicles and drones, to permit the network adjusting to modifying topologies.

Step 6: Implement Drone-based Communication and Data Relaying

  1. Designate Drones as Relay Nodes:
    • Assign drones to perform like relay nodes that supporting to bridge interaction among the disconnected vehicles.
    • Drones can obtain, save and send, data packets, to make sure that vehicles without a direct line of interaction can even swap the information.
  2. Simulate Data Collection and Dissemination by Drones:
    • Set drones, from several vehicles gathering information and it to a centralized server or another vehicle.
    • Drones can be collected incident information and relay it to emergency services in emergency situations.
  3. Implement Data Offloading Mechanisms:
    • Offload data from congested or heavily loaded vehicles, to give precedence critical data like safety or emergency messages across routine information utilising drones.

Step 7: Configure VANET Traffic and Applications

  1. Set Up VANET Traffic Patterns:
    • In the VANET, replicate diverse kinds of traffic to utilize NS3 applications:
      • Safety Messages: Set up broadcast messages for road safety data.
      • Data Relaying: Replicate the video or sensor data relaying using UDP or TCP flows.
      • Emergency Messages: Mimic high-priority messages to experiment the ability of drones to rapidly transmit critical data.
  2. Adjust Data Rates and Packet Sizes:
    • Configure diverse data rates, packet sizes, and intervals to replicate distinct network conditions like urban (high density) or rural (low density).
  3. Prioritize Data Relaying by Drones:
    • Execute the rules within the drones’ relaying function to give precedence to emergency or high-priority messages across regular data, to make sure periodically delivery.

Step 8: Run Simulation Scenarios

  1. Define Testing Scenarios:
    • Baseline Scenario: Execute the VANET without drones, monitoring standard connectivity, latency, and throughput parameters.
    • Drone-assisted Scenario: We insert drones to offer more connectivity and to minimize latency. Then, equate outcomes to the baseline situations.
    • Emergency Scenario: Estimate how drones support data transmitting and replicate an emergency including unexpected rise within high-priority traffic.
    • Sparse Network Scenario: Experiment the VANET including low vehicle density, measuring how successfully drones sustain the connectivity in remote areas.
  2. Test Different Densities and Drone Coverage:
    • Test with diverse vehicle and drone densities, monitoring how the existence of drones impacts the performance of network.

Step 9: Collect and Analyze Performance Metrics

    • Gather simulation information such as latency, throughput, packet delivery ratio, connectivity duration, and hop count utilizing NS3’s tracing and logging tools.
    • For in-depth packet-level data, allow ASCII and PCAP tracing that is helpful for examining the data relaying performance and connectivity.
  2. Evaluate Drone-assisted VANET Performance:
    • Equate performance parameters among the drone-assisted and non-drone scenarios to measure how drones enhance the network performance.
    • We study the parameters such as connectivity enhancement, minimized latency, and maximized packet delivery rates.
  3. Analyze Data Relaying and Offloading Effectiveness:
    • Now, we assess how efficiently drones transmit the information among vehicles that particularly within situations along with sparse or high-speed vehicle movement.

Step 10: Optimize and Experiment with Advanced Drone-based VANET Features

  1. Optimize Drone Flight Paths:
    • Experiment diverse flight patterns like circular, grid to increase the coverage and connectivity whereas reducing energy usage.
