Importance of localization for tracking mobile target in wireless sensor network

Localization is very important factor in the wireless sensor network while tracking a mobile target. In this paper introduction of various localization techniques are given. Location of node is important, to know the target node location in the surveillance area. Also the energy saving algorithm which is Low Energy Adaptive Cluster Hierarchy algorithm is used in this paper. Various concern parameters considered in this paper are Packet Drop, Packet Delivery ratio and Throughput. Packet Drop during communication is sensitive area in wireless sensor network and elimination of packet drop is one of the important parameter considered here. Because of that packet delivery ratio is eventually high. Throughput is high during this operation of target tracking.
