OMNeT++ Source Code

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.

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.
