Reliable geocasting for underwater acoustic sensor networks

Abstract

UnderWater Acoustic Sensor Networks (UW-ASNs) [1] are envisioned to enable applications for oceanographic data collection, environmental monitoring, navigation, and tactical surveillance. Geocasting, which is the transmission of packet(s) to nodes located in a certain geographic region, is becoming a crucial communication primitive for these applications. In UW-ASNs, geocasting may be required to assign tasks to underwater vehicles or to query sensor nodes in a certain region.
