Network Covalent Solids

Network Covalent Solids

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...

Hybrid Zones

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Protein Networks

Protein Networks

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,...

Hybridization of Atomic Orbitals I

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Background:

Wireless Body Area Networks (WBANs) are crucial for remote medical health monitoring.
Critical challenges exist in WBANs regarding reliability, energy efficiency, and Quality of Service (QoS) for life-critical data.
Dynamic body-shadowing and heterogeneous traffic patterns complicate Medium Access Control (MAC) protocol design in WBANs.

Purpose of the Study:

To propose a novel hybrid MAC protocol, Nash Bargaining Rate-optimization MAC (NBR-MAC), for WBANs.
To address the challenges of balancing reliability, energy efficiency, and QoS in WBANs for medical data.
To enhance the performance of WBANs through intelligent rate allocation.

Main Methods:

Developed NBR-MAC, a hybrid protocol integrating TDMA-based Guaranteed Time Slots (GTS) and CSMA/CA-based contention access.
Modeled WBAN rate allocation as an Asymmetric Nash Bargaining Game with a rigorous disagreement point.
Normalized the utility function to incorporate sensor priority, buffer status, and channel quality, deriving the Nash Bargaining solution.

Main Results:

NBR-MAC enhances the transmission success ratio and throughput for WBANs.
The protocol effectively reduces packet age and energy consumption under various load conditions.
Simulation results validate the protocol's performance improvements.

Conclusions:

NBR-MAC offers a robust solution for WBAN MAC protocol design, balancing critical performance metrics.
The Nash Bargaining approach provides guaranteed minimum service for critical medical data.
The proposed protocol is suitable for reliable and efficient medical health monitoring applications.
