Summary
This study introduces opportunistic multipath routing to boost packet delivery in long-hop wireless sensor networks. The new method significantly cuts energy use and enhances data transmission reliability.
Area of Science:
- Computer Science
- Network Engineering
- Wireless Communication
Background:
- Wireless sensor networks (WSNs) face challenges in packet delivery ratio (PDR) with increasing network length.
- Existing routing protocols incur significant overhead in long-hop WSNs, degrading performance.
- Multipath, opportunistic, and learning-based routing have limitations in long-hop scenarios.
Purpose of the Study:
- To propose a novel opportunistic multipath routing scheme for long-hop WSNs.
- To address the overhead issue inherent in traditional long-hop routing protocols.
- To enhance packet delivery ratio and reduce energy consumption.
Main Methods:
- Developed an opportunistic multipath routing protocol incorporating path number forecasting.
- Implemented a bifurcation strategy based on opportunistic routing and reliability requirements.
- Enabled intermediate nodes to dynamically select transmission nodes and adapt to path failures.
Main Results:
- The proposed scheme significantly improves packet delivery ratio in long-hop WSNs.
- Demonstrated substantial energy consumption reduction, ranging from 33% to 65%, compared to existing protocols.
- Performance gains were validated under an 80% link success ratio.
Conclusions:
- The proposed opportunistic multipath routing scheme effectively overcomes limitations of existing protocols in long-hop WSNs.
- Achieved a superior balance between packet delivery performance and energy efficiency.
- Offers a viable solution for reliable and energy-conscious data transmission in extensive WSN deployments.

02:12Short-distance Transport of Resources
17.5K
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.

01:23Propagation of Action Potentials
9.0K
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

01:11IP3/DAG Signaling Pathway
14.3K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

01:17Passive Diffusion: Overview and Kinetics
1.3K
Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
