| Summary: | 碩士 === 國立交通大學 === 資訊科學系所 === 92 === Sensor network technique enhances our ability to monitor and observe the physical world. Many recently researches for sensor network focus on routing, nodes cooperation and energy consumption. In addition to these topics, localization service is an important function in sensor network system. In this thesis, we will present a multiple power-levels localization algorithm for wireless sensor network. We also discuss the boundary of our algorithm and evaluate the performance in different environment. The simulation results show that our algorithm can reach much better accuracy than traditional single power-level methods. In critical situations such as reference node failure, unstable radio transmission range and beacon collision, our algorithm performs well. We believe that this algorithm is suitable for sensor network.
