Energy efficient localization for isolated wireless sensor networks

Abstract

Wireless Sensor Network WSN is made up of the interconnection newlineof sensor nodes Sensor nodes sense the environment and send the report to newlinethe Control Station CS for further actions In hostile environment newlineUnmanned Aerial Vehicle UAV is used to deploy the sensor nodes as newlineexplained by Ou Ssu 2008 After deployment battery of sensor nodes newlinecannot be recharged or replaced with manual intervention as stated by newlineJantarasorn Prommak 2012 The power failure isolates the sensor nodes newlinefrom the WSN and produces serious consequences Hence the energy newlineconservation in hostile environment based WSN applications is very newlineimportant newline newline
