Exploring and monitoring the underwater world using underwater sensors is drawing a lot of attention these days.In this field cooperation between acoustic sensor nodes has been a critical problem due to the challenging features such as acoustic channel failure,long propagation delay of acoustic signal,limited bandwidth and loss of connectivity.There are several proposed methods to improve cooperation between the nodes by incorporating information/game theory in the node’s cooperation.However,there is a need to classify the existing works and demonstrate their performance in addressing the cooperation issue.In this paper,a review to investigate various factors affecting cooperation in underwater acoustic sensor networks was conducted.Various cooperation techniques used for underwater acoustic sensor networks from different perspectives were studied with concentration on communication reliability,energy consumption and security,and a taxonomy for underwater cooperation was presented.Moreover,how the game theory could be applied to make the nodes cooperate with each was reviewed furtherly.Different cooperative game methods,where their performance on different metrics was compared and analyzed furtherly.Finally,open issues and future research direction in underwater acoustic sensor networks were highlighted.
