The interest in monitoring applications using underwater sensor networks has been growing in recent years. The severe communication restrictions imposed by underwater channels make that efficient monitoring be a challenging task. Though a lot of research has been conducted on underwater sensor networks, there are only few concrete applications to a real-world case study. In this work, hence, we...

In this work, we evaluate the performance of a bidirectional teleportation protocol on an IBM Q Experience quantum processor six or more qubits. Moreover, analyze viability in implementation mentioned configuration composed by two submerged nuclear submarines opposite sides ocean and satellite that generates distributes entangled pairs, transmits optical bits disambiguation to those buoys locat...

The potential benefits of massive multiple-input multiple-output (MIMO) make it possible to achieve high-quality underwater acoustic (UWA) communications. Nevertheless, due the wideband nature UWA channels, existing MIMO techniques for radio frequency cannot be directly applied This paper investigates a system in shallow-water environment, deploying large array apertures at both transmitter and...

Laser sensing has been applied in various underwater applications, ranging from underwater detection to laser underwater communications. However, there are several great challenges when profiling underwater turbulence effects. Underwater detection is greatly affected by the turbulence effect, where the acquired image suffers excessive noise, blurring, and deformation. In this paper, we propose ...

The success of multicarrier modulation in the form of orthogonal-frequency-division-modulation (OFDM) in radio channels illuminates a clear path one could take towards high-rate underwater acoustic communications. However, earlier work on the application of OFDM in underwater has only had limited success. We aim to make OFDM work in underwater and build a practical multicarrier modem prototype....

The objective of this paper is to present a downsized prototype of an Autonomous Underwater Vehicle (AUV) designed with the idea of dealing with cooperative tasks involving multiple agents. The entire system has been designed for marine and underwater environmental surveillance and protection. The agents provide an interesting point in the surveillance of shallow coastal waters and shallow wate...

This article presents an empirical model for the noise of the acoustic underwater channel in shallow water from the analysis of field data measurements. A probability density function for the noise amplitude distribution is proposed and the associated likelihood functions are derived. As a result, an expression to the probability of symbol error for binary signaling is presented for the channel...
