Energy is termed as the Cluster Head
Energy efficient clustering routing protocols (EECRP) has received much concentration in wireless sensor network. In these protocols, the low powered compact sensing nodes are separated into minor groups such as clusters. One among the nodes in a cluster network is elected with more responsibilities of data transmission than compared to other nodes. This unique node is termed as the Cluster Head (CH), and the other nodes in the cluster are referred to as cluster members. Cluster members transfer their information to the cluster head.
Then, the CH performs the concept of data aggregation to collect the data from the cluster child and then forwards that data to the Base station (BS).
