Performance analysis of an energy optimization scheme for cluster based heterogeneous sensor networks

Abstract

A Wireless Sensor Network WSN consists of a large number of newlinesensor nodes deployed over a geographical area for monitoring physical newlinephenomena like temperature humidity vibrations seismic events and so on newlineThe critical issue in WSNs is represented by the limited availability of energy newlinewithin the network and hence optimizing energy consumption is very newlineimportant Most existing work on sensor networks consider homogeneous newlinesensor networks where all sensor nodes are assumed to have the same newlinecapability in terms of communication computation memory storage energy newlinesupply reliability and other aspects Heterogeneous Sensor Network HSN newlineconsists of two physically different types of sensor nodes and can newlinesignificantly improve sensor network performance in terms of energy newlineconsumption newline newline
