Field Experiments of Underwater Image Transmission for AUV

AUV Application for Inspection of Underwater Communications

Regular inspection of underwater communications (pipelines and cables) is actual problem of modern oil and gas industry. Specially equipped vessels, towed underwater devices and remote operated vehicles /ROV/ are applied for these purposes as usually, but quality of acquired data does not always allow revealing emergencies at the proper time. “Spot” inspections by ROVs give difficultly comparab...

Development of Test-Bed AUV ‘ISiMI’ and Underwater Experiments on Free Running and Vision Guided Docking

Optimum bit rate for image transmission over underwater acoustic channel

In this paper, image transmission in underwater channels is considered. The images are encoded with forward error correction using an unequal error protection technique together with the Reed-Solomon codes and dynamic bit-rate allocation before transmitted. This paper proposes a novel rate allocation scheme for efficient image bit stream transmission in underwater acoustic channels with optimum...

Virtual UEP for Progressive Image Transmission in Underwater Communication

Due to its applications in marine research, oceanographic, and undersea exploration, underwater communication has been recently under intense investigation. Although underwater communication has been improving its performance (in terms of bandwith, QoS, etc.), image transmission in autonomous underwater vehicles (AUVs) networks is still considered a frontier work. Here, we address the progressi...

Constructing a Distributed AUV Network for Underwater Plume-Tracking Operations

In recent years, there has been significant concern about the impacts of offshore oil spill plumes and harmful algal blooms on the coastal ocean environment and biology, as well as on the human populations adjacent to these coastal regions. Thus, it has become increasingly important to determine the 3-D extent of these ocean features (‘plumes’) and how they evolve over time. The ocean environme...
