ABSTRACT
The Wireless sensor networks (WSN) consisting of a large number of sensors that are effective for gathering data
in a variety of environments, as the sensor operate on battery which is of limited power. To support high
scalability and better data aggregation in fixed base station communication, sensor nodes are often grouped into
disjoint, non overlapping subsets called clusters. Clusters create hierarchical WSN which incorporate efficient
utilization of limited resources of sensor nodes. These clusters are formed by specialized cells. Each cluster is
managed by a special node called cluster head and advanced node. An algorithm for better cluster head selection
based on the node energy and the distance from base station to the cluster head for the efficient transmission and
to reduce energy consumption by the sensor nodes is proposed in this paper. And the same algorithm is compared
with the LEACH algorithm in terms of energy consumption.
