Clustering

Grouping of similar objects or sensors in our context

• Distance or proximity
• Logical organizing

Topology control approach

• Load balancing, network scalability

Types of clustering

• Static: local topology control

   

• Dynamic: changing network parameters

   

• Single hop and multi hop

   

• Homogeneous and heterogeneous

Advantages of Clustering

Transmit aggregated data to the data sink

• reducing number of nodes taking part in transmission

Useful energy consumption

Scalability for large number of nodes

Reduces communication overhead for both single and multi hop
