One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency.
Clustering is a method to make the consumed energy efficient. LEA

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

In wireless sensor networks, the power resource of
each sensor node is limited. Minimizing energy dissipation and
maximizing network lifetime are important issues in the design
of routing protocols for sensor networks. In this paper, Cluster

LEACH [1] is an autonomous adaptive clustering protocol that distributes the
energy load evenly among the sensors in the network using randomization. The
nodes organize themselves into local clusters, with one node acting as the local
base stat
