  Underwater communication networks are increasingly popularized by various
important maritime applications. However, this also leads to an increased
threat landscape. This letter presents the first study that considers jamming
attacks by random jammers present in the surroundings of legitimate
transceivers in underwater acoustic communication systems. We investigate the
impact of jamming attacks on various performance parameters of the legitimate
underwater acoustic communication link. In particular, we investigate the
legitimate link using stochastic geometry for important performance parameters,
namely coverage probability, average rate, and energy efficiency of the link
between two legitimate nodes, i.e., underwater and surface nodes. We then
derive and present tractable expressions for these performance parameters.
Finally, we performed a Monte Carlo simulation to validate our analysis. We
plot the performance metrics against the transmit power, and jamming power for
different intensities of the jammers in shallow, mid, and deep water scenarios.
Results reveal that on average, jamming in deep water has a relatively high
impact on the performance of legitimate link than in shallow water.
