Certain investigations on energy optimization algorithms for clustered heterogeneous sensor networks with mobile sink

Abstract

Wireless Sensor Networks WSNs are densely deployed energy constrained battery operated newlineAd hoc networks The number of nodes present in the network is higher than ad hoc networks also it is data centric and not address centric Each and every node present in the network is battery operated The nodes are deployed either deterministically or randomly Energy optimization is a very important requirement in Wireless Sensor Networks because of their limited battery power The applications of Wireless Sensor Networks range from environmental monitoring to civilian one Usually sensor nodes are static and nowadays the applications are extended to dynamic environments Hence sensor nodes may be a movable one where nodes are attached to moving objects people or animal The main motive of this research is to increase the lifetime of the Wireless Sensor Networks with reduced energy consumption Energy consumption and scalability are critical issues in performance degradation of Wireless Sensor Networks Clustering technique is mainly used to reduce energy consumption The heterogeneity of devices in Wireless Sensor Network has to be taken into account for increasing the network performance and lifetime newline
