An Energy Efficient Prediction-Based Technique for Tracking Moving Objects in WSNs

Wireless Sensor Networks applications are attracting more and more research, especially in energy saving techniques which is the focal point of most researchers in this area. One of the most interesting applications of Wireless Sensor Networks is the Object Tracking Sensor Networks (OTSNs) which are used mainly to track certain objects in a monitored area and to report their location to the application´s users. This application is a major energy consumer among other Wireless Sensor Networks applications. In this paper, we propose the Prediction-based Tracking technique using Sequential Patterns (PTSP), which is designed to achieve significant reductions in the energy dissipated by the OTSNs, while maintaining acceptable missing rate levels. PTSP is tested against basic tracking techniques to determine the appropriateness of PTSP in various circumstances.
