Certain investigations on the energy and reliability constraints of heterogeneous wireless sensor networks

Abstract

The Wireless Sensor Networks WSNsare extensively used in newlinemany applications like precision agriculture environment monitoring habitat newlinemonitoring battlefield surveillance disaster rescue operations etc The WSN newlinenodes solely depend on battery for power and they are deployed mostly in newlineopen and harsh environmental conditions and are expected to work newlineunattended for a long duration newlineProlonging the lifespan of the network and improving the reliability newlineof the reported results are therefore most important to the success of the newlineenergy constrained and reliability craved WSNs This dissertation work newlinestrives to address both these objectives successfully It assumes a newlineheterogeneous clustered network architecture and two types of traffic models newlineviz Periodic and Eventdriven newline newline
