This paper focuses on underwater acoustic (UA) communications and proposes a
decentralized spectrum sharing method for noncooperative orthogonal frequency-division …

In this paper, we present the design and implementation of a software defined orthogonal
frequency division multiplexing (OFDM)-based underwater acoustic (UWA) communication …

Sharing the available resources within the underwater acoustic spectrum by a huge number
of users will definitely end up with the problem of resource allocation. This problem is due to …

In this paper, we provide self-configuration and adaptation capabilities to UWSN thanks to Q-
learning. UWSN deployed for the long term over large areas for environmental monitoring …

Decentralized resource sharing for multiple noncooperative underwater acoustic (UWA)
communication links is investigated. Point-to-point links, considered as rational players, are …

Noncooperative underwater acoustic (UWA) communication systems are prone to interfere
with each other since the limited resource offered by the channel is not regulated by any …

The contribution of this paper is twofold. First we evaluate the performance of adaptive
power allocations for multiuser communications in underwater acoustic channels. The study …

This paper aims at studying underwater acoustic OFDM communication systems interfering
with each others in the same channel. We propose a decentralized spectrum sharing …

L'onde acoustique est utilisée par de nombreux systèmes et organismes marins pour
communiquer, naviguer ou inférer de l'information sur l'environnement. Le développement …

La capacité à communiquer efficacement sous l'eau sans liaison filaire revêt un intérêt
majeur pour de nombreuses applications liées à la sûreté, l'analyse, l'exploration ou …
