Adaptive Target Tracking in Sensor Networks

چکیده
Recent advances in processor, memory and radio technology have enabled cheap nodes capable of sensing, communication and processing. Networks of distributed microsensors are rapidly emerging as a feasible solution to a wide range of data gathering applications. However, the key impediments to successful deployment of microsensor nodes are their energy and longevity constraints. We propose a quality aware information collection protocol in sensor networks for tracking applications. The protocol explores trade-off between energy and application quality to significantly reduce energy consumption in the sensor network thereby enhancing the lifetimes of sensor nodes. Simulation results over elementary movement patterns in a tracking application scenario strengthen the merits of our adaptive information collection framework.
