Energy Efficient Technique for Cluster Head Selection and Data gathering in Wireless Sensor Network

Wireless sensor Networks are widely deployed for wide
range of applications for gathering information about the
desired application. However the limited battery power
of the sensor nodes requires efficient gathering of
information so the Network performance and lifetime is
increased. LEACH [13] is one the famous cluster-based
structure, which has been widely proposed in wireless
sensor Networks. In this paper, we propose a clusterhead
formation algorithm that increases the performance
of the Network. Our protocol has the following
characteristics. All nodes after the first round send
energy level and distance information from the base
station (BS) to the cluster-head. Cluster head send the
energy level and distance information of each node to
base station (BS).Base station selects the cluster-head
dynamically on the basis of energy level and distance.
To overcome these two parameters our algorithm will
show better performance and increase the lifetime of the
network.
