How to Implement 3D MANET Massive Users in OMNeT++

To implement the 3D Mobile Ad Hoc Network (MANET) Massive users in OMNeT++, we have to simulate a large number of mobile nodes in 3D space. It is used to learn network performance in situation like drone swarms, urban environments with multiple levels, or large-scale IoT deployments. In this following, we deliver the step-by-step details to execute this in OMNeT++:

Steps to Implement 3D MANET with Massive Users in OMNeT++

  1. Install OMNeT++ and INET Framework:
    • Make certain that OMNeT++ and the INET framework are installed. INET offers essential models for wireless communication, mobility, and routing in MANETs.
  2. Define the Network Topology:
    • Generate a network topology using a .ned file, postulating a large number of mobile nodes. These nodes will travel in a three-dimensional space and communicate with one another wirelessly.
  3. Implement 3D Mobility Models:
    • In INET, use or customize existing mobility models to simulate the 3D movement of nodes. Models like RandomWaypointMobility or GaussMarkovMobility can be extended to operate in three dimensions.
  4. Configure the Routing Protocol:
    • Pick and set up a routing protocol suitable for MANETs, such as AODV (Ad hoc On-Demand Distance Vector) or DSR (Dynamic Source Routing). These protocols will handle the dynamic routing of packets amongst mobile nodes.
  5. Simulate Massive Users:
    • Create a large number of nodes (e.g., hundreds or thousands) in the network, making certain that the simulation scales to manage this volume of users. This may need tuning OMNeT++’s performance parameters.
  6. Configure the Simulation Environment:
    • Use the .ini file to configure parameters like the number of nodes, simulation time, mobility speed, and network area dimensions. The set up should reflect a 3D environment.
  7. Run the Simulation and Analyze Results:
    • Implement the simulation and evaluate the performance of the MANET in 3D space. Key metrics like packet delivery ratio, end-to-end delay, network throughput, and how well the routing protocol scales with the number of users.

Example: Implementing a 3D MANET with Massive Users

  1. Define the Network Topology in a .ned File

// MANET3DNetwork.ned

package networkstructure;

import inet.node.inet.WirelessHost;

import inet.mobility.single.RandomWaypointMobility;

network MANET3DNetwork

{

parameters:

int numNodes = default(100);  // Number of nodes in the network

submodules:

node[numNodes]: WirelessHost {

@display(“p=100,100”);

mobility.typename = “inet.mobility.single.RandomWaypointMobility”;

}

}

  1. Implement 3D Mobility for Nodes

Extend the RandomWaypointMobility to peform in a 3D space by setting up the Z-axis.

mobility RandomWaypointMobility

{

@display(“i=block/mobility”);

initialX = uniform(0m, 1000m);

initialY = uniform(0m, 1000m);

initialZ = uniform(0m, 500m);  // Z-axis for 3D mobility

speed = uniform(1mps, 20mps);  // Speed of nodes

updateInterval = 0.1s;

}

  1. Configure the Routing Protocol

Configure a MANET routing protocol like AODV in the .ini file.

network = networkstructure.MANET3DNetwork

sim-time-limit = 300s

# Node and network settings

*.node[*].wlan.mac.maxQueueSize = 1000

*.node[*].wlan.phy.transmitter.power = 2mW

*.node[*].mobility.bounds = “1000m 1000m 500m”  # 3D space dimensions

# Routing protocol configuration

*.node[*].hasGlobalARP = false

*.node[*].routingProtocol = “AODV”

  1. Explanation of the Example
  • Network Topology (MANET3DNetwork.ned):
    • The network contains a large number of mobile nodes (numNodes), each using the WirelessHost module.
    • Nodes are configured with a 3D mobility model (RandomWaypointMobility) that permits them to move in a 3D space.
  • 3D Mobility Configuration:
    • The mobility model is extended to contain the Z-axis, enabling movement in three dimensions. Nodes move inside a stated 3D space (1000m x 1000m x 500m).
  • Routing Protocol (AODV):
    • The AODV routing protocol is configured to handle the dynamic routing of packets in the MANET. The .ini file settings set up AODV and other network parameters.

Running the Simulation

  • Compile the project in OMNeT++ IDE and run the simulation.
  • Use OMNeT++’s tools to assess how the MANET performs in a 3D environment with a large number of nodes. Concentrate on metrics such as packet delivery ratio, delay, and routing overhead.

Extending the Example

  • Different Mobility Models: Execute and compare various mobility models (e.g., GaussMarkovMobility, LinearMobility) to see how they impact network performance in 3D.
  • Scalability Testing: Examine the scalability of the network and the performance of the routing protocol by raising the number of nodes.
  • Realistic 3D Environments: Simulate more complex 3D environments like urban areas with difficulties or indoor environments with multiple floors.
  • QoS-aware Routing: Incorporate QoS metrics into the routing protocol to make certain that high-priority traffic is routed with lower delay and packet loss.
  • Interference and Fading: Model wireless channel intrusion and declining to simulate more realistic communication conditions in a dense 3D MANET.

Through this set up, we covered the basic simulation, installation, configuring 3D mobility and routing protocol to accomplish the 3D MANET with Massive Users using INET and OMNeT++. For further requirements, we will offer them over another simulation.
