近年來隨著全球工業化的不斷演進與擴張，加上大量船隻頻繁往來各地水域，使得水污染(例如：原油或透明化學原料外洩、有害藻類增生等)的情形日益嚴重。這些污染源若無法有效監控與清除，不但會危害水中生態，甚至影響整個地區的經濟效益。有鑑於此，本碩士論文將提出一套基於佈建在水面之無線感測網路(Water-surface Wireless Sensor Network, 簡稱WWSN)之水污染偵測與追蹤系統，簡稱AquaView。此系統以架構叢集式網路為基礎，讓水面上大量的感測節點不需維護額外的地理資訊(例如：鄰點座標、全域或區域性的網路拓墣等)，便能迅速得知自身何處，並於感測範圍內，有效地偵測及追蹤逐漸擴散的污染源遍及之輪廓。經由Qualnet模擬軟體實驗結果證明，AquaView展現優異地監控效能與穩定性。

Spilled invisible pollutions, such as oil or biochemical materials, damage not only the ocean environment but also the regional economics. To prevent such damages from expanding, a wireless sensor network deployed over the ocean, referred to as Water-surface Wireless Sensor Network (WWSN) in this study, is a suitable candidate for timely monitoring of such wide range and continuous moving objects. In WWSN, this study develops an aquatic-pollution detection and tracking scheme, designated as AquaView, based on an autonomous self-localization cluster mechanism. The proposed scheme enables each normal sensor node to automatically discover its location without maintaining the addition information (i.e., the locations of neighboring nodes, a global or a subset of network topology, and so forth) and to efficiently detect and track the boundary of the current moveable pollution in its sensing field. The numerical results obtained using a Qualnet simulator confirm the effectiveness and robustness of the proposed approach.
