摘要

在無線感測網路中，目標追蹤是一重要應用。因此，目標追蹤成為熱門討論與研究的議題。在目標追蹤的過程中節能效益是很重要的議題，因此根據無線感測網路的各種限制，我們提出一個目標追蹤的機制，它能輕易達成低成本且高精確度之即時監測。在本研究裡，主要是利用目標移動特性與歷史資訊，來選擇合適的監測節點，確保能將目標物完全覆蓋住，同時這些監測節點也將負責目標定位與追蹤的工作，並讓能源分配的更有效益，達成追蹤品質與節能之間的平衡。模擬結果顯示我們所提出的方法具有即時監測、精確定位與節省能源之優點。

Target tracking is one of an important application in wireless sensor networks, hence, target tracking has become a widely studied subject. This study proposed a target tracking method which can perform low-cost and highly precise real-time monitoring according to various restrictions of wireless sensor networks. In this study, the moving characteristics and historical information of the target were used for selecting appropriate secondary nodes, and these secondary nodes were in charge of target positioning and tracking, so as to use the energy more efficiently and reach a balance between tracking quality and energy saving. The simulation result showed that the proposed method has the advantages of real-time monitoring, precise positioning, and energy saving.
