Energy efficient cluster head selection to enhance network connectivity for wireless sensor network

Abstract

Wireless sensor based communication system is an ever growing sector in the industry of communication. Wireless infrastructure is a network that enables correspondence between various devices associated through a infrastructure protocol. In WSN enhancing the life span of network depends on the energy dissipation of the sensor devices. Reducing the energy dissipation of sensor devices will improve the lifetime and device failure which help in better connectivity and coverage of sensor network. There has been various approach that has been developed to improve energy efficiency of sensor network among that clustering is a significant technique that help in improving the network lifetime by reducing the energy consumption but the issues with existing methodology is the energy inefficiency in selecting the cluster head which result in loss of connectivity which reducing the life time of network. To overcome this here the author proposes a design for cluster head selection based on connectivity of node. The experimental result shows that the proposed PS-LEAH perform better than existing LEACH in term of network lifetime, number of active device.
