摘要：Ocean bottom sensor nodes can be used for oceanoraphic data collection, pollution monitoring, offshoreexlo-ration and tactical surveillance applications. Moreover, Un-manned or Autonomous Underwater Vehicles (UUVs,AUVs), equipped with sensors, will find application in exploration of natural undersea resources and gathering ofscientific data in collaborative monitoring missions. Underwater acoustic network- ing is the enabling technology forthese applications. Underwater Networks consist of a variable number of sensors and vehicles that are deployed toperform collaborative monitoring tasks over a given area. In this paper, several fundamental key aspects of underwateracoustic communications are investigated. Different architectures for two-dimensional and three-dimensionalunderwater sensor networks are discussed, and the underwater channel is char-acterized. The main challenges for thedevelopment of efficient networking solutions posed by the underwater environment are detailed at all layers of theprotocol stack. Furthermore, open research issues are discussed and possible solution approaches are outlined.
