Summary
This study introduces an energy-efficient location-based opportunistic routing protocol (EELORP) for underwater acoustic sensor networks (UASNs). EELORP enhances data transfer quality and reduces delay, outperforming existing protocols in simulations.
Area of Science:
- Underwater acoustic sensor networks (UASNs)
- Internet of Underwater Things (IoUTs)
- Wireless sensor networks
Background:
- Underwater acoustic sensor networks (UASNs) face challenges like node mobility, propagation delay, energy constraints, and interference.
- Location-based opportunistic routing protocols offer potential for improved Quality of Service (QoS) in UASNs.
Purpose of the Study:
- To review existing location-based opportunistic routing protocols for UASNs, identifying limitations and challenges.
- To propose an energy-efficient and easy-to-implement location-based opportunistic routing protocol (EELORP) for UASNs.
Main Methods:
- A comprehensive review of current location-based opportunistic routing protocols for UASNs.
- Development and simulation of the proposed Energy-Efficient Location-Based Opportunistic Routing Protocol (EELORP) using Aqua-Sim.
Main Results:
- Existing hybrid protocols are often complex, have high overhead, and struggle with communication voids.
- The proposed EELORP demonstrates superior performance in terms of QoS and energy efficiency compared to existing protocols.
- EELORP effectively addresses challenges in data transfer for UASN-assisted Internet of Underwater Things (IoUTs) platforms.
Conclusions:
- EELORP offers an efficient and practical solution for data routing in UASNs.
- The protocol is suitable for various UASN applications, including Internet of Underwater Things (IoUTs).
- EELORP significantly improves QoS and energy efficiency while reducing communication delay.

16.6K
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.

01:07Propagation of Waves
2.5K
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
