Target Tracking Using WSN For Effective Energy Utilization

Abstract
Wireless Sensor Network (WSN) contains a no of sensor nodes which collect information process them and send the information to the sink for further processing.WSN can be operated in harsh places where human presence is risky. Wireless network lifetime is dependent on batteries of sensor nodes and replacing and recharging batteries is impossible Target tracking is the most significant application of wireless sensor network (WSN).Due to various issues in wireless sensor network such as limited batteries, high mobility of node, sensor node failure, unpredictable environment target tracking become challenging task. Therefore, new algorithm is proposed called brink detection with help of face tracking. It helps to track the target in timely fashion and recover from special cases. Keywords- Wireless Sensor Network, Face tracking, Path finding ,path tolerance ,Network Lifetime.
