Certain investigations on energy efficient cluster based multilevel hierarchical routing scheme in wireless sensor networks

Abstract

Wireless Sensor Network WSN is one of the well known emerging technologies of the 21st century WSN raise the interactions between humans and environment to a new level In recent years WSN has attracted a lot of attention from researchers in both academic and industrial communities WSN consist of tiny, energy efficient sensor nodes communicating via wireless channels performing distributed sensing and collaborative tasks for a various monitoring applications include monitoring of temperature humidity vibrations seismic events pollution detection etc newlineThe need and emergence of WSN in versatile applications have driven the research community over the years and made WSN phenomenon a reality These networks are characterized by a limited amount of energy supply at the sensor nodes and hence the energy optimization in sensor nodes becomes a vital design challenge for WSN Clustering technique effectively reduces the energy consumption of sensor nodes and has been widely adopted for data gathering and routing in WSNs A variety of clustering protocols have been proposed to address the energy efficiency problems in different network scenarios newline newline
