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 ...

Connecting with oceans using underwater acoustic networks
XRDS: Crossroads, The ACM Magazine for Students, 2014Oceans cover a majority of our planet and are currently lacking in regards to exploration and technological innovations. One technology that can help enable more aquatic applications is underwater acoustic networks (UANs). This article discusses the current status of UANs, the new applications that can be provided, and the challenges faced by this ...

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

Distortion analysis of underwater acoustic sensor networks
2015 7th International Conference on New Technologies, Mobility and Security (NTMS), 2015The paper studies the distortion performance of multihop underwater acoustic sensor networks. The network is composed of bottom mounted sensors and the sensor to sensor links experience Ricean fading. The distortion is evaluated for the case when there is interference from other sensors in the network.
