Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

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).

Background:

Self-localization is crucial for drifted underwater acoustic networks (DUANs) applications.
DUANs face localization challenges due to insufficient anchors and dynamic network topology.

Main Methods:

Developed an optimal reference selection scheme to mitigate insufficient anchors.
Proposed a dynamic reference selection algorithm adapting to predicted network topology changes.
Simulated the DRSL algorithm's performance under various DUAN conditions.

Main Results:

DRSL significantly increases localization accuracy with insufficient anchors.
