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.
