UNFOLD: UNiform Fast On-Line Boundary Detection for Dynamic 3D Wireless Sensor Networks
A wireless sensor network becomes dynamic if it is monitoring a time-variant event (e.g., expansion of oil spill in ocean). In such applications, on-line boundary detection is a crucial function, as it allows them to track the event variation in a timely fashion. However, the problem becomes very challenging as it demands a highly efficient algorithm to cope with the dynamics introduced by the evolving event. Moreover, as many physical events occupy volumes rather than surfaces (e.g., oil spill again), the algorithm has to work for 3D cases. To this end, the authors propose UNiform Fast On-Line boundary Detection (UNFOLD) to tackle the challenge.
