Summary
This study introduces three new routing techniques for underwater wireless sensor networks (UWSNs) to improve data delivery. These methods enhance packet delivery ratio and reduce energy consumption compared to existing protocols.
Area of Science:
- Underwater Wireless Sensor Networks (UWSNs)
- Wireless Communication Protocols
- Network Routing Algorithms
Background:
- Underwater wireless sensor networks (UWSNs) face challenges with sparse networks and void holes, leading to inefficient data routing.
- Existing routing techniques like Hydrocast can result in lengthy paths and high energy consumption.
- Optimizing data transmission and reliability is crucial for effective UWSN operation.
Purpose of the Study:
- To propose three novel opportunistic pressure-based routing techniques for UWSNs: Co-Hydrocast, improved-Hydrocast, and Co-improved Hydrocast.
- To enhance data packet delivery ratio and minimize energy consumption in UWSNs.
- To address challenges of void holes and lengthy routing paths in sparse UWSN environments.
Main Methods:
- Sensor nodes strategically deployed to maximize network field monitoring and minimize path length.
- Greedy algorithm employed for energy-efficient data packet transmission.
- Opportunistic routing and relay cooperation with Maximal Ratio Combining (MRC) for reliable delivery and improved Signal-to-Noise Ratio (SNR).
Main Results:
- The proposed Co-Hydrocast, improved-Hydrocast, and Co-improved Hydrocast schemes demonstrate superior performance over the existing Hydrocast technique.
- Significant improvements observed in packet delivery ratio.
- Reduced energy consumption achieved through optimized routing paths and transmission strategies.
Conclusions:
- The developed opportunistic routing techniques effectively improve data transmission reliability and energy efficiency in UWSNs.
- Strategic node deployment and cooperative mechanisms are vital for overcoming UWSN limitations.
- The proposed methods offer a promising solution for robust underwater sensor network communication.

To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water.

02:12Short-distance Transport of Resources
17.9K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

3.4K
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...

01:09Radiation Pressure: Problem Solving
901
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Osmosis is a process where solvent molecules move toward a solution through a semipermeable membrane. As the solution dilutes due to the entry of solvent, it expands. This expansion increases the hydrostatic pressure of the solution. When the hydrostatic pressure equals the osmotic pressure, osmosis stops.Osmotic pressure, denoted by Π, is the minimum pressure needed to prevent the solvent from passing into the solution by osmosis. The van 't Hoff equation calculates the osmotic pressure...
