understand hierarchical approach in wsn

The proposed routing protocol for Wireless Sensor Network is hierarchical and cluster based. The protocol supports mobility in the Sensor Nodes as well as in the Sink. The entire protocol is described in terms of two phases namely Setup Phase and D

The cluster head is selected by the random number generated by nodes in the hierarchical routing protocol which is implementing Low Energy Adaptive Clustering Hierarchy (LEACH). As a result, the cluster head may be chosen randomly and be
