碩士 === 大同大學 === 資訊工程學系(所) === 98 === In recent years, the wireless sensor network technology used in health care is well developed and mature. Therefore, people can use the characteristics of wireless sensor network to locate the position when monitored patient’s physiological is showing warning message. The advantage of this system is that patient can be found without any delay. It also can solve the problem about lack of person who takes care of child. In this thesis, we study the methods and the problems that may cause deviation on ZigBee position locator and propose a method to improve the accurate of position location. The result shows that on average there will have over 25% improvement as compare to Circle Intersection Points (CIP) algorithm and Circle Intersection Lines (CIL) algorithm.
