Summary
This study introduces a new epidemic model for wireless rechargeable sensor networks (WSNs) that accounts for virus mutation and sensor energy levels. The model aims to improve virus control strategies in these networks.
Area of Science:
- Computer Science
- Network Security
- Epidemiology
Background:
- Virus spreading in wireless rechargeable sensor networks (WSNs) is a growing concern.
- Existing epidemic models often overlook sensor rechargeability and virus mutation.
Purpose of the Study:
- To propose a novel epidemic model for WSNs incorporating rechargeable sensors and virus mutation.
- To analyze the stability of the proposed model and develop optimal control strategies.
Main Methods:
- Developed a new epidemic model with states: susceptible, infected, variant, low-energy, and dead.
- Employed characteristic equations and Lyapunov functions for stability analysis.
- Formulated an optimal control problem using Pontryagin's maximum principle.
Main Results:
- The stability of the novel epidemic model was mathematically analyzed.
- An optimal control strategy was formulated to mitigate virus spread and reduce network costs.
- Numerical simulations validated the theoretical findings.
Conclusions:
- The proposed model effectively addresses virus spread in WSNs with rechargeable sensors and mutation.
- Optimal control strategies can significantly reduce virus impact and network operational costs.
- This research provides a foundation for enhanced network security and resilience.

00:36Viral Mutations
36.5K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

01:09Mutation, Gene Flow, and Genetic Drift
60.4K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Mutations are heritable changes in an organism’s genome involving alterations in the base sequence of DNA or RNA. These changes can influence cellular processes and phenotypic traits, potentially transforming the unaltered wild type into a mutant form. Such changes, termed forward mutations, are pivotal in shaping the genetic diversity of organisms.RNA viruses exhibit the highest mutation rates due to the absence of robust proofreading mechanisms during genome replication. In contrast,...

00:57Viral Recombination
24.2K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

01:20Infection
9.5K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...
