OMNeT++ Source Code

In this OMNET++ source code section we are going to discuss about the clustering process in networks.

Cluster:

  • In General,clustering is known as grouping of nodes in a network.
  • Clustering Process works in a way where two systems in a network behave like a single system.

We Provide solutions for all types of protocol in a network for OMNeT++ simulation. Get best projects for simulation based on OMNeT++ with source code for all types of Protocol.

OMNeT++ Ad Hoc Network Simulation Projects

Clustering protocols:

  • LEACH.
  • Pegasis.
  • TEEN.
  • APTEEN.
  • LEACH-C.
  • WEP.
  • TDEEC.
  • TL-LEACH.
  • EEHC.
  • HEARP.

 

Reasons for introducing cluster:

  • Optimal route selection.
  • Fault tolerance.
  • Energy efficiency.
  • Load balancing.
  • Avoid network partitioning .
  • Parallel processing.
