As over 70 percent of the earth's surface is covered by water, it is desirable to deploy underwater sensor networks to support oceanic research. Under Water Sensor Networks (UWSNs) use acoustic waves and are characterized by long and variable propagation delays, intermittent connectivity, limited bandwidth and low bit rates. Energy savings have always been(More)
Marine pollution by oil spills is a devastating environmental hazard, requiring a low-cost efficient system for continuous and real-time thickness measurement and localization of floating oil. Knowing that none of the previous detection methods has managed to fully meet these requirements, it is necessary to devise a new technique to guide and speed-up the(More)
Energy savings have always been the primary concern in sensor network protocols; however there are applications where latency and throughput are prioritized over energy efficiency and are so significant that the application would not satisfy its requirements without them. Although existing duty-cycle MAC protocols such as S-MAC, T-MAC and Z-MAC are power(More)
