| contents | Optical Communication in Free Space (FSO) bids more radio bandwidth, operates under a gratis license, and has a lower startup cost as compared to Radio Frequency (RF). Nonetheless, its vulnerability to variations in atmospheric meteorological circumstances is a concern. Ultimately, the purpose of this study is to use Principal Component Analysis (PCA) with Artificial Neural Networks (ANN) to design a QoS prediction model for a terrestrial FSO communication connection. To accomplish the specified goal, meteorological data such as visibility, wind speed, and altitude were collected from the Weather Services in South Africa (SAWS) archive during a ten-year duration at five different locations: George, Johannesburg, Kimberly, Bloemfontein, and Polokwane. The eigenvalues of the first Principal Component (PC1) and the second Principal Component (PC2) in the PCA across the stations Bloemfontein, Johannesburg, Kimberly, George, and Polokwane are 7.624 and 1.020, 7.234, and 0.984, 6.204 and 1.723, 7.354 and 0.876, and 7.104 and 0.865, respectively, demonstrating that, they are kept as QoS variables to train the Artificial Neural Network (ANN) model as they provide the most compelling interpretation of the original variable data. The RMSE values of every proposed model across all the study locations are 0.1437, 0.2131, 0.2329, 0.1101, and 0.1977, respectively. Based on the RMSE, the proposed performed better over George. A realistic and accurate predictive model is developed for each of the study locations. Thus, the developed model will serve as a valuable tool for maintaining good QoS in FSO network services and improving telecom businesses in South Africa. |
