An energy-efficient cluster head selection of LEACH protocol for wireless sensor networks

Abstract

As of the technological growth, Wireless Sensor Networks (WSNs) becomes an emerging research area. Sensors are combined as group called clusters to collect the data from where it is deployed. Clusters are maintained by Cluster Head (CH) and it maintains the transmission process which needs high energy. LEACH Protocol is considered for this work and in which the CHs are elected based on threshold function. The proposed methodology enhances the threshold function of LEACH with distance and count of neighbor nodes metrics develops better energy efficient function. Power Amplification for the elected CH chosen high power in order to increase the performance of the network. The number of alive nodes and residual energy of a node based on distance metrics are checked with the existing model. The simulation result shows the proposed scheme achieves high impact than the existing methodologies for WSNs.
