How to Implement Network cluster transmission in OMNeT++

To implement the network cluster transmission within OMNeT++ has comprises mimicking a network where nodes are prepared into clusters, and data is transmitted within and among these clusters. This method is frequently used in wireless sensor networks (WSNs) or IoT systems to enhance energy consumption, improve data aggregation, and expand communication efficiency.

Given below is a process to execute the network cluster transmission in OMNeT++.

Steps to Implement Network Cluster Transmission in OMNeT++

  1. Set Up OMNeT++ Environment:
    • Make sure OMNeT++ and the INET framework are installed and configured properly.
    • If working on a wireless sensor network or IoT application, consider using or expanding frameworks such as MiXiM or Castalia, which are tailored for such scenarios.
  2. Design the Network Architecture:
    • State a network topology where nodes are grouped into clusters.
    • Allocate one node in each cluster as the cluster head (CH), responsible for handling intra-cluster communication and transferring aggregated data to other clusters or a base station.
  3. Implement Clustering Algorithm:
    • Execute or customize an existing clustering algorithm, like LEACH (Low-Energy Adaptive Clustering Hierarchy), to dynamically create clusters and choose cluster heads.
    • The algorithm would consider factors such as node energy levels, distance to the base station, or communication load when creating clusters and choosing CHs.
  4. Configure Intra-Cluster and Inter-Cluster Communication:
    • Set up intra-cluster communication, where member nodes transfer data to their corresponding cluster heads.
    • Form inter-cluster communication, where cluster heads transfer combined data to a base station or another cluster heads.
  5. Simulate and Monitor Cluster Transmission:
    • Run simulations to monitor how data is transmitted in clusters and how cluster heads aggregate and send data.
    • Observe the performance of the clustering algorithm and the effectiveness of data transmission in terms of latency, throughput, and energy consumption.
  6. Analyse and Visualize Results:
    • Use OMNeT++’s visualization tools to monitor the clustering process and data transmission paths.
    • Examine metrics like complete network performance, stability, energy efficiency, and cluster formation stability.

Example Configuration

Given below is an instance configuration for executing cluster transmission in OMNeT++:

[General]

network = ClusterTransmissionNetwork

sim-time-limit = 500s

[Config ClusterTransmissionNetwork]

*.numNodes = 20

*.numClusters = 4

# Assign nodes to clusters

*.node[*].clusterId = -1  # Initially unassigned

*.node[0].clusterId = 0

*.node[1].clusterId = 0

*.node[2].clusterId = 1

*.node[3].clusterId = 1

*.node[4].clusterId = 2

*.node[5].clusterId = 2

*.node[6].clusterId = 3

*.node[7].clusterId = 3

# Repeat for all nodes

# Define the cluster heads (e.g., node[0], node[2], node[4], and node[6])

*.node[0].isClusterHead = true

*.node[2].isClusterHead = true

*.node[4].isClusterHead = true

*.node[6].isClusterHead = true

# Define the mobility model (if applicable)

*.node[*].mobility.type = “StaticMobility”

# Configure communication parameters

*.node[*].transceiver.type = “IdealWirelessNic”

*.node[*].transceiver.range = 100m

*.node[*].transceiver.dataRate = 250kbps

# Implement clustering and transmission algorithm

*.node[*].clusteringAlgorithm = “LEACH”

*.node[*].transmissionProtocol = “ClusterTransmission”

# Monitor clustering and transmission performance

*.node[*].monitorClustering = true

*.node[*].monitorTransmission = true

Example Scenarios

  1. Scenario 1: Energy-Efficient Data Transmission
    Execute a scenario where nodes periodically transfer data to their cluster head, which then aggregates and forwards the data to the base station. Examine the energy consumption of nodes, specifically the cluster heads, and monitor how well the clustering algorithm balances the load.
  2. Scenario 2: Dynamic Cluster Formation
    Mimic a scenario where nodes periodically re-calculate and create clusters based on their energy levels or other norms. Observe how the clustering algorithm adapts to variations in node energy levels and the impact on network longevity and stability.
  3. Scenario 3: Multi-Hop Inter-Cluster Communication
    Execute a multi-hop communication scenario where data from detached clusters is relayed through middle cluster heads to reach the base station. Calculate the impact on energy consumption, packet delivery ratio, and latency.

Considerations:

  • Cluster Head Rotation: Execute mechanisms to periodically rotate cluster heads between nodes in a cluster to evenly deliver the energy consumption and prevent early depletion of particular nodes.
  • Scalability: Examine the clustering algorithm and transmission protocol in larger networks to make sure they scale efficiently with an increasing number of nodes and clusters.
  • Fault Tolerance: Analyse adding fault tolerance mechanisms where the network can recuperate and re-form clusters if a cluster head fails or becomes inaccessible.

In this setup, we had offered the detailed informations, basic process with instances are helps to implement and analyse the network cluster transmission in the tool OMNeT++ using INET framework.
