Buoyancy and Stability for Submerged and Floating Bodies

In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Area of Science:

  • Optical Wireless Communication
  • Underwater Networks
  • Data Transmission

Background:

  • Underwater optical wireless communication faces challenges like turbidity and limited transmission distances.
  • Maintaining consistent data transmission capacity and signal quality in dynamic underwater environments is crucial.

Purpose of the Study:

  • To propose and evaluate a bidirectional underwater optical wireless communication network with dynamic path switching.
  • To maximize data transmission capacity and ensure reliable communication by adapting to channel conditions.

Main Methods:

  • Implementing a system that dynamically switches between underwater and aerial optical paths.
  • Utilizing adaptive modulation and beam steering techniques to overcome underwater channel impairments.
  • Conducting experiments to evaluate performance under varying underwater distances and beam steering misalignments.

Main Results:

  • Switching to an aerial path beyond 1.8 m underwater significantly improved performance, maintaining consistent SNR and bit rates.
  • The system demonstrated high transmission capacity and SNR stability with increasing underwater distances.
  • 4K UHD video streaming showed reduced degradation and near-original quality with 20 ms latency when switching to the aerial path.
  • A 2-degree beam steering misalignment caused a 12 dB SNR loss and reduced capacity by 222 Mbps.

Conclusions:

  • Dynamically utilizing underwater and aerial optical paths based on channel conditions enables reliable and efficient data transmission.
  • The proposed hybrid approach is a viable solution for next-generation underwater optical wireless communication networks.
  • Adaptive strategies are key to overcoming the inherent limitations of underwater optical communication.
