Buoyancy and Stability for Submerged and Floating Bodies

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:

Computer Science
Electrical Engineering
Marine Technology

Background:

Underwater wireless sensor networks (UWSNs) face challenges in maintaining stable network topologies due to the dynamic underwater environment.
Existing UWSN schemes often struggle with centralized control, node failures, and network malfunctions like isolation and loops.

Purpose of the Study:

To propose SOUNET, a novel self-organized underwater wireless sensor network (UWSN) with a tree topology for robust data gathering.
To enhance network connectivity, reliability, and energy efficiency in UWSNs.

Main Methods:

SOUNET employs a self-organized approach where sensor nodes discover network topology via packet flooding.
Nodes dynamically update parent nodes using time-varying neighbor tables to ensure optimal connectivity.
Malfunctions such as node isolation and closed loops are addressed through a simple, integrated resolution mechanism.

Main Results:

SOUNET demonstrates superior network connectivity compared to conventional schemes.
The proposed network achieves a higher packet delivery ratio (PDR).
SOUNET exhibits improved energy consumption across the network.

Conclusions:

SOUNET provides a highly connected and self-adaptive UWSN without centralized control.
The system effectively resolves common self-organized network issues.
Experimental validation confirms SOUNET's efficacy in real-world underwater environments.
