Performance analysis of WSN–FSO system modeled by Gamma–Chi-square channel distribution 2023 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/9252 https://kirj.ee/proceedings-of-the-estonian-academy-of-sciences-publications/?filter[year]=2023&filter[issue]=1270&filter[publication]=11277&v=8cee5050eeb7 J. Todorović B. Jakšić P. Spalević M. Dobrojević I. Milovanović This paper presents the WSN–FSO (wireless sensor network–free-space optics) system based on CCR (corner cuberetroreflector) and modeled with Gamma–Chi-square distribution. The expressions of ABER (average bit error rate) for the receivedsignal under conditions of different levels of atmospheric turbulence are calculated. Numerical results are presented in the form ofgraphs, and the results are confirmed by the Monte Carlo simulation. Graphs are presented for different Rician factor values, linklengths, and different levels of atmospheric turbulence. The obtained results are compared with the existing results for other FSOchannel distribution models. After thorough consideration we conclude that Gamma–Chi-square gives a better system performancein terms of ABER. article https://doi.org/10.3176/proc.2023.1.04 72 1, 2023 30 40 1736-7530 Proceedings of the Estonian Academy of Sciences
