Channel simulation for underwater acoustic communication network
Proceedings of the Seventh ACM International Conference on Underwater Networks and Systems - WUWNet '12, 2012Significant advancements in underwater acoustic communication have been achieved in recent decades. In the dynamic ocean environment, various physical processes can significantly affect the communication channel. The time-varying underwater channel has both deterministic and stochastic features. Due to the dynamic environment and the complex properties

Cooperative multihop communication for underwater acoustic networks
Proceedings of the 1st ACM international workshop on Underwater networks - WUWNet '06, 2006In this work, multi-hop cooperative schemes for underwater sensor networks are studied and shown to be highly energy efficient. Also, the signal model for a multipath channel is derived taking into account the interference from other nodes. It is shown that while the effects of uncompensated intersymbol interference (ISI) can be quite detrimental, the ...

Optimizing Adaptive Communications in Underwater Acoustic Networks
OCEANS 2019 MTS/IEEE SEATTLE, 2019We consider an Underwater Acoustic Network (UAN) where each node is equipped with a suite of signals and so there is the flexibility to aim for different bit rates at each transmission slot. A Cross-Entropy (CE) centralized algorithm is explored to optimize the combination of modulation scheme and transmission power level in the presence of unreliable ...

Secure communication for underwater acoustic sensor networks
IEEE Communications Magazine, 2015UASNs are widely used in many applications, and many studies have been conducted. However, most current research projects have not taken network security into consideration, despite the fact that a UASN is typically vulnerable to malicious attacks due to the unique characteristics of an underwater acoustic communication channel (e.g., low communication
