How to Implement Network Path planning AUV in OMNeT++

To implement the network path planning for Autonomous Underwater Vehicles (AUVs) in OMNeT++, we have to emulate the movement of AUVs in an underwater environment in which they need to navigate via waypoints or to a target destination as they taken into account for factors like obstacles, energy constraints and communication limitations. Follow the provided steps to implement it in OMNeT:

Steps to Implement Network Path Planning for AUVs in OMNeT++

  1. Set Up OMNeT++ Environment:
    • Make sure to install both the OMNeT++ and INET framework.
    • For underwater communication and AUV-specific mobility models, we may need to expand or design new modules.
  2. Design the AUV Network Architecture:
    • Describe a network topology that has AUVs and potentially other underwater nodes (e.g., sensors, buoys).
    • Identify communication links that simulate underwater communication characteristics like acoustic communication, which has restricted bandwidth and high latency.
  3. Implement AUV Mobility and Path Planning:
    • Generate or extend mobility models to simulate the movement of AUVs. These models should consider underwater constraints like limited manoeuvrability and energy consumption.
    • Deploy path planning algorithms, includes A* or Dijkstra’s algorithm, to compute optimal paths from the AUV’s current position to the target destination, considering obstacles and energy constraints.
  4. Configure Communication Between AUVs:
    • Execute communication protocols that permit AUVs to transmit information regarding their positions, path plans, or environmental data.
    • Consider multi-hop communication if AUVs need to relay messages over other nodes to reach their destination.
  5. Simulate and Monitor AUV Movement:
    • Run simulations to monitor how AUVs navigate their environment, evade obstacles, and reach their target destinations.
    • Observe the success of the path planning algorithm in terms of energy efficiency, distance traveled, and the ability to avoid obstacles.
  6. Analyze and Visualize Results:
    • Use OMNeT++’s visualization tools to find the AUVs’ paths and evalute their performance.
    • Assess metrics like the efficiency of the path planning, communication latency, and overall mission success rate.

Example Configuration

Here’s an example configuration for an AUV network with path planning in OMNeT++:

network = AUVPathPlanningNetwork

sim-time-limit = 300s

[Config AUVPathPlanningNetwork]

*.numAUVs = 3

*.auv[0].type = “AUVNode”

*.auv[1].type = “AUVNode”

*.auv[2].type = “AUVNode”

*.auv[0].mobility.type = “AUVMobility”

*.auv[0].mobility.startPositionX = 100m

*.auv[0].mobility.startPositionY = 200m

*.auv[0].mobility.startPositionZ = -50m

*.auv[0].mobility.targetPositionX = 500m

*.auv[0].mobility.targetPositionY = 800m

*.auv[0].mobility.targetPositionZ = -50m

*.auv[1].mobility.type = “AUVMobility”

*.auv[1].mobility.startPositionX = 150m

*.auv[1].mobility.startPositionY = 250m

*.auv[1].mobility.startPositionZ = -50m

*.auv[1].mobility.targetPositionX = 550m

*.auv[1].mobility.targetPositionY = 850m

*.auv[1].mobility.targetPositionZ = -50m

*.auv[2].mobility.type = “AUVMobility”

*.auv[2].mobility.startPositionX = 200m

*.auv[2].mobility.startPositionY = 300m

*.auv[2].mobility.startPositionZ = -50m

*.auv[2].mobility.targetPositionX = 600m

*.auv[2].mobility.targetPositionY = 900m

*.auv[2].mobility.targetPositionZ = -50m

# Implement path planning algorithm

*.auv[*].pathPlanningAlgorithm = “AStarAlgorithm”

# Define communication parameters

*.auv[*].transceiver.type = “AcousticModem”

*.auv[*].transceiver.range = 1000m

*.auv[*].transceiver.dataRate = 1kbps

# Monitor AUV movements and path planning decisions

*.auv[*].monitorMovement = true

*.auv[*].monitorPathPlanning = true

Example Scenarios

  1. Scenario 1: Basic Path Planning with Obstacles
    Execute a scenario where AUVs need to navigate around static hindrances to reach their destinations. Use the A* algorithm to discover the shortest path and see how effectively the AUVs evade hurdles.
  2. Scenario 2: Energy-Constrained Path Planning
    Mimic a scenario where AUVs have limited energy resources, and the path planning algorithm needs to track the most energy-efficient route. Evaluate how the algorithm balances the trade-off amongst distance travelled and energy consumption.
  3. Scenario 3: Multi-AUV Coordination
    Implement a scenario where multiple AUVs need to coordinate their movements to accomplish a common goal like mapping an area or searching for an object. Observe how well the AUVs communicate and collaborate, and how the path planning algorithm adapts to differs in the environment.

Considerations:

  • Underwater Communication: Execute realistic underwater communication models, considering the limitations of acoustic modems like low bandwidth, high latency, and signal attenuation.
  • Dynamic Obstacles: Consider scenarios with dynamic obstacles like other AUVs or underwater currents that require real-time modifications to the prearranged path.
  • Environmental Factors: Integrate environmental factors like water currents, which can influence AUV mobility and path planning.
