Abstract

wireless sensor network enables the regular
monitoring of military ,civil and other application. This paper
proposes a new improved cluster algorithm of LEACH protocol
which is intended to balance the energy consumption of the
entire network and extend the lifetime of the network . In this
paper we propose a leach protocol that works on network layer
in OSI model. Leach protocol stands for Low-Energy Adaptive
Clustering Hierarchy , a clustering-based protocol that utilizes
randomized rotation of local cluster base stations (clusterheads)
to evenly distribute the energy load among the sensors in
the network . LEACH is able to distribute energy dissipation
evenly throughout the sensors, doubling the useful system
lifetime for the networks we simulated.. It proides a better
results than conventional protocols.
