The transmission distances are investigated by optimizing the place of the relay nodes at a target outage probability of 10(-6). In this study, the numerical results reveal that the optimum transmission distances are increased for both the whole power margins and different number of relay nodes with the help of the proposed optimization technique.eninfo:eu-repo/semantics/closedAccessOpticsFree-space optical communicationRelay-assisted transmissionAtmospheric turbulence fadingOutage probabilityOptimum transmission distanceDecode and forward relayingDifferential evolution algorithmDiversityAtmospheric turbulenceDecodingEvolutionary algorithmsLight transmissionOptimizationOutagesDecode-and-forward relayingDifferential evolution algorithmsFree space optical communicationOptimum transmissionRelay-assisted transmissionsOptical communicationArticle0003777341000342-s2.0-849797825976490649712716OpticsFree-Space Optical Communication; Atmospheric Turbulence; Free Space
