A resilient pressure routing scheme for underwater acoustic networks

Underwater Acoustic Networks (UANs) are a transformative technology that is helping expand military, commercial and scientific applications in deep sea environments. The nature of network deployment in these deep sea environments has spurred a new paradigm in network routing known as pressure routing. Pressure routing is based on geographic routing but only uses limited location information, namely depth information, to route data from the sea floor to the surface. Recent work has shown that existing pressure routing protocols are vulnerable to malicious intrusions. In this paper we propose a resilient pressure routing protocol that seeks to reduce the effectiveness of malicious attackers, such as spoofing attacks. We evaluate our proposed protocol in a simulation environment and show that it reduces the effectiveness of spoofing attacks and maintains routing performance with minimal trade-off.
