    Abstract: 無線感測器網路（Wireless Sensor Network , WSNs）是由匯集點(Sink)及許多感測器節點所組成的網路，具有可大範圍監視環境及進行無線通訊的特性，其中使用的感測器節點成本低且體積小且具備感測事物、資料處理及無線通訊的能力。感測器節點的優點也相對的帶來了些許限制，其中對無線感測器網路效能影響最直接的莫過於在電量上的限制，在移動目標物追蹤機制上如何盡可能地減少電量的消耗以達到持續性的追蹤目標物，是一項極為重要的課題。
    本篇論文提出一個應用於網格式無線感測器網路之有效的移動目標物追蹤機制(An Efficient Mechanism for Mobile Target Tracking in Grid-based Wireless Sensor Networks)，利用網格式架構網路的優點，判斷目標物可能進入的網格進而讓這些網格內的感測器節點來感測目標物，其餘的感測器節點則進入睡眠模式，有效地降低無線感測器網路追蹤目標物時所消耗的電量，同時提高整體網路的存活時間。
    Wireless Sensor Networks (WSNs) is composed of sinks and multiple sensor nodes, which can monitor large-scale environment and do wireless-communication. All the sensor nodes not only have several advantages, such as low-cost and compact -size, but also can do data sensing and data processing, even wireless communication. Relatively, to sensor nodes, the greatest challenge among those is the constraints on energy. The most critical issue is how to minimize the energy consumption for keeping .target tracking to devise the mobile target tracking mechanism in WSNs.
    Therefore, we propose a solution on the basis of the advantages of Grid-based network (An Efficient Mechanism for Mobile Target Tracking in Grid-based Wireless Sensor Networks), which could determine where the target might be in the grids, and then those sensor nodes do track the target; others turn into sleep mode, this mechanism could efficiently reduce the energy consumption, and even prolongs the whole network lifetime.
