Implementation of a Wireless Underwater Video Link
Autonomous underwater vehicles (AUVs) are increasingly being considered for remotely supervised missions, primarily for routine subsea inspection tasks currently performed by tethered remotely operated vehicles (ROVs). This project is a step in the development of a high speed, networked wireless communication capability for AUVs using MIT Sea Grant's softwaredefined Reconfigurable Modem (R-Mode...
متن کاملHigh Rate OFDM Acoustic Link for Underwater Communication
A high bit rate acoustic link over an underwater channel is investigated . Design of a Digital communication system utilizing acoustic signals for underwater applications is a very challenging field due to the extremely complex nature of the underwater channel. The conventional techniques for overcoming the channel effects used in communication systems elsewhere fail to give the desired results...
متن کاملImproved AUV Autonomy Provided by an Underwater Acoustic Link ̈ § ̈ § ̈ ̈
GESMA (Groupe d’Etudes Sous-Marines de l’Atlantique), initiated a project named TRIDENT (TRansmission d’Images et de Données EN Temps réel) a few years ago. The project’s objective is to develop a high data rate link allowing the transmission of different information (text, images...). A real-time receiver platform based on a spatiotemporal equalizer developed by ENST Bretagne, was carried out ...
متن کاملUnderwater Electromagnetic Sensor Networks—Part I: Link Characterization †
Underwater Wireless Sensor Networks (UWSNs) using electromagnetic (EM) technology in marine shallow waters are examined, not just for environmental monitoring but for further interesting applications. Particularly, the use of EM waves is reconsidered in shallow waters due to the benefits offered in this context, where acoustic and optical technologies have serious disadvantages. Sea water scena...
متن کاملA Glider-Assisted Link Disruption Restoration Mechanism in Underwater Acoustic Sensor Networks
Underwater acoustic sensor networks (UASNs) have become a hot research topic. In UASNs, nodes can be affected by ocean currents and external forces, which could result in sudden link disruption. Therefore, designing a flexible and efficient link disruption restoration mechanism to ensure the network connectivity is a challenge. In the paper, we propose a glider-assisted restoration mechanism wh...
