Game Theory-Based Cooperation for Underwater Acoustic Sensor Networks: Taxonomy, Review, Research Challenges and Directions

“…The field of underwater acoustic networks has attracted a lot of attention in the research community, recently. Many applications such as environmental and pollution monitoring [ 2 , 19 , 20 ], oceanographic data collection [ 2 ], distributed surveillance [ 17 ], oceanic sampling [ 21 ], offshore exploration [ 2 , 20 ], disaster prevention [ 2 ], mine reconnaissance [ 2 ] among others are developed. However, there are many challenging issues that contribute to the UASNs performance degradation that include high energy consumption, loss of connectivity, security, routing and cooperation [ 20 , 22 , 23 ].…”

“…The importance of underwater applications is attracting the attention of researchers which in turn has led to the rapid growth of research within various areas in Underwater Acoustic Sensor Networks (UASNs) [ 1 ]. UASNs comprise sensor nodes capable of sensing, processing and communicating the sensed data to the appropriate destination which are deployed underwater for an effort in backing vast range of applications in collaborative monitoring tasks [ 2 , 3 ]. Recently, many researchers are focusing on how to develop different underwater applications to support the lives of living organisms underwater and even those that are living on the sea floor by the use of collaborative, cooperative and frequent monitoring of underwater environments [ 4 ].…”

“… Nodes are prone to failures due to corrosion and fouling. Fading and multipath problems make the acoustic channel impaired severely [ 2 , 3 ]. …”

Review on research challenges and strategies in underwater sensor networks

“…In an energyconstrained underwater system it is significant to discover techniques to increase the life expectancy and to minimize the delay of the network. [28,52]. …”
