Energy-Efficient Target tracking Algorithms in Wireless Sensor Networks: An Overview

Wireless sensor networks find its application in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. Energy efficiency is one of the important research issues in WSNs, since it determines the lifetime of the sensor network deployed for the intended applications. Target tracking is one of the killer applications of wireless sensor networks and energy-efficient target tracking algorithms are used for accurate tracking. In this paper, the focus is mainly driven over the survey of the energy-efficient target tracking routing algorithms for Wireless Sensor Network.
