Accordingly, this study develops an aquatic-pollution detection and tracking scheme, designated as AquaView, based on a Wireless Sensor Network deployed over an offshore region (i.e., a Waterborne Wireless Sensor Network (WWSN)) to track the moving boundary of a pollution spill such that cleanup operation can be effectively monitored and controlled.
The concepts of segment insertion and subdivision (moving boundary within the segment) are adopted in this model to track the phase change point along the flow channel.
A front tracking and heat conserving solution is presented for a moving boundary problem.
