摘要

由於無線網路技術的大量發展，以及微電子元件的進步、通訊技術的進步，使得無線感測器網路(Wireless sensor network)也發展起來。而無線感測器網路中所使用的感測器節點(sensor node)同時具有感測、計算和無線通訊的能力。因此，無線感測器網路的應用也相當地廣泛。
近年來，在無線感測器網路中，定位的議題已經是主要的研究之一，針對定位的議題，本論文提出一個在無線感測器網路中利用移動的參考點之定位機制，此機制主要是利用移動的參考點，再加上全球定位系統(GPS)的輔助，讓未知座標的感測器節點算出自己的座標之後，再透過鄰近的感測器節點將自己的座標資訊傳回基地台(Base station)。透過此一定位機制能算出感測器節點的座標位置，進而讓無線感測器網路可用於追蹤或是有效率傳送資料的應用。

Since the mass development of the wireless network, the advancement in wireless communications and micro-electronics element promote the development of wireless sensor networks (WSNs). The sensor nodes of WSNs have the following abilities such as: sensing, computation, and wireless communication capabilities. Hence, WSNs can be used for various application domains.
Recently, the localization issue in the WSNs has become an important research topic. In this thesis, we propose a location mechanism with mobile reference nodes and Global Positioning System (GPS) to help sensor nodes to calculate the coordinate location information. And then sensor nodes deliver the coordinate location to base station through neighboring sensor nodes.
By using this mechanism, we can calculate the coordinate location of the target sensor nodes. And then we can apply this mechanism to track or transfer data packets in the WSNs efficiently.
