摘要：Wireless Sensor Networks (WSNs) are increasingly being envisioned for collecting data, such as physical or e nvironmental properties, from a geographical region of interest . WSNs are composed of a large number of low - cost sensor nodes, which are powered by portable power sources. The existing system presented Probability - based Prediction and Sleep Scheduli ng prot ocol (PPSS) to improve energy efficiency of proactive wake up. It does not provide optimality constraints and abrupt direction changes. The proposed system presented Optimal Sleep Schedule and Directional Target Prediction scheme (OSS - DTP) to improve track ing performance of sensor network in abrupt directional changing targets. It supports multiple target tracking sensor networks. It achieves better energy efficiency in handling multiple targets. T o manage tracking subareas it reduces number of proactively awakened nodes. Simulati ons were conducted on different sensor nodes to measure the performance in terms of Target speed, energy saving ratio and target detection delay.
