A genetic algorithm based selection of a transmission wavelength in the LOS optical wireless channel

This paper presents a genetic algorithm selection technique of appropriate transmission wavelengths in the line-of sight (LOS) optical wireless channel, under different weather conditions. The overall deterministic attenuations are usually presented in an international code of visibility model, and the changes in visibility decide about the wavelength control margin. However, the proposed work suggests a comprehensive method that analyses non-uniform weather conditions, and specifies a practical range that the genetic algorithm can work in. The paper considers the fact that instantaneous attenuations are not stable and they form a variable link margin that should be analytically studied for perfect wavelength selection.
