Jamming the Underwater: a Game-Theoretic Analysis of Energy-Depleting Jamming Attacks
2019
Underwater sensor networks can be employed in both military and environmental remote coastal monitoring applications, such as enemy targeting and identification, and tsunami prevention. Jamming can be a serious issue in these networks, typically composed by battery-powered nodes, as an attacker can not only disrupt packet delivery, but also reduce the lifetime of energy-constrained nodes. In this work, we consider a malicious jammer with the dual objective of preventing communication and depleting the battery of a targeted underwater sensor node. The jammed node may use packet-level coding as a countermeasure against the attack, so as to increase its chances of correctly delivering its information to the legitimate receiver. We model this scenario as a multistage game, derive the optimal long-term strategies for both sides, and evaluate how the position of the jammer affects the communication of the legitimate network.
