Abstract

Nowadays, Free Space Optical (FSO) communication has attained great importance because of high features such as large data rate, low power, and huge bandwidth. However, FSO technology suffers from several atmospheric effects such as rain, snow, fog, etc. To overcome these issues, an innovative Selective Active Relay (SAR) protocol is proposed in this research. Here, the SAR method is utilized for selecting the relays in FSO, which is used for better communication without any difficulties like atmospheric conditions. Also, a novel Water Pouring Erbium-Doped Fiber Amplifier (WPEDFA) method is introduced to allocate the power for relays and calculates the outage probability. Moreover, the current research introduces an innovative Optimum Enhanced African Buffalo (OE-AB) algorithm to optimize the error and outage probability. Eventually, the proposed approach analyzes the Bit Error Rate (BER) and Quality factor (Q-factor) under atmospheric conditions. Also, the proposed WPEDFA approach is utilized for allocating power to the relays. Moreover, the OE-AB algorithm optimizes the error rate and outage probability. Also, the simulation of this model is done by MATLAB, and attained results prove the effectiveness of the proposed approach. Consequently, it achieves a lower BER and outage probability compared with other techniques.
