    Abstract: 近年來,無線通訊系統中的無線感測網路 (Wireless Sensor Networks)快速興起,己經成為目前學術單位及業界積極參與的一個重要領域。它最主要的潛在用途包括環境監測、智慧型居家保全及交通運輸管理或監測…等。 利用無線感測網路來進行特定的裝置來進行追蹤或定位,一直是在無線感測網路中非常重要的研究主題及應用。由於無線感測網路的本身的特性可以應用於各種不同的環境,不必受限於室內、室外或天氣的因素所造成的問題。但其缺點由於無線感測網路是由無線通訊系統所延伸出來的因此無法能夠有精確的定位。為了希望能夠減少這部份的誤差,我們利用其他的定位技術來協助修正,使定位精確度能夠提高。 本系統是以無線感測網路為主加上紅外線輔助,所產生的高度精準度的定位系統,特別適合用於行動型裝置,為了能夠達到高精準的定位及移動時的誤差修正,此系統是直接在行動裝置上面進行定位計算及誤差修正,同時間將計算的結果透過無線感測網路回傳至後端伺服器。 Wireless Sensor Network fast rise sharply recently, and become an important field that academia, and industrial participate in zealously. It has potential to environment monitor, smart home security system, and traffic manages…etc. In Wireless Sensor Network, the mobile device positioning and tracking are very importation research topic and application. No matter in indoor, outdoor or harsh climate environment, the Wireless Sensor Network still can work very well, but it is not very accurately because that is a wireless communication technology, for this reason we could get more accurate information and error correction by other technologies like infrared system. We proposed accuracy positioning system for mobile device, and it is combine Wireless Sensor Network, and infrared technology. The positioning procedure and error correction are operating on mobile device, and reply positioning information to server by Wireless Sensor Network.
