Summary
This study introduces a new routing protocol for mobile wireless sensor networks (MWSN) that enhances network lifetime by considering node connectivity and energy. The proposed LEACH-MEEC protocol improves data delivery and balances energy consumption effectively.
Area of Science:
- Computer Science
- Wireless Communication
- Network Engineering
Background:
- Network lifetime in mobile wireless sensor networks (MWSN) is critically dependent on energy-efficient routing protocols.
- Existing methods often select cluster leaders (CL) based solely on remaining energy, potentially limiting network longevity.
Purpose of the Study:
- To propose a novel connectivity-based routing protocol, LEACH-MEEC (Low-Energy Adaptive Clustering Hierarchy-Mobile Energy Efficient and Connected), for MWSN.
- To enhance network lifetime, improve data delivery, and balance energy consumption in MWSN.
Main Methods:
- Developed the LEACH-MEEC protocol, which selects cluster leaders based on both node connectivity and remaining energy.
- Evaluated performance using metrics such as the number of alive nodes (NAN), remaining energy (RE), and packet delivery ratio (PDR).
- Investigated the impact of different mobility models, including the Reference Point Group Mobility model (RPGM).
Main Results:
- The LEACH-MEEC protocol demonstrated superior performance compared to existing algorithms, primarily due to the integration of the connectivity metric.
- LEACH-MEEC effectively improved data delivery, extended network lifetime, and achieved balanced energy consumption.
- The Reference Point Group Mobility model (RPGM) was identified as a more effective mobility model for MWSN performance.
Conclusions:
- The proposed LEACH-MEEC protocol offers a significant advancement in energy-efficient routing for MWSN.
- Incorporating node connectivity into cluster leader selection is crucial for optimizing network lifetime and performance.
- RPGM is recommended for simulating MWSN environments to achieve better performance outcomes.

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

2.9K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

01:22Routes of Drug Administration: Overview
9.6K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
