Abstract
Abstract Free Space Optics (FSO) communication provides attractive bandwidth enhancement with unlicensed bands worldwide spectrum. However, the link capacity and availability are the major concern in the different atmospheric conditions. The reliability of the link is highly dependent on weather conditions that attenuate the signal strength. Hence, this study focuses to mitigate the weather and geographic effects using iterative optimization on FSO communication. The optimization maximizes the visibility distance while guaranteeing the reliability by minimizing the Bit Error Rate (BER). The wireless optical communication system is designed for the data rate of 10 Gbps. The performance of the proposed wireless optical communication is compared against the literature in terms of visibility distance, quality factor, BER, and Eye diagram at different atmospheric conditions. The simulation results have shown that the proposed work has achieved better performance.
Highlights
The wireless communication has shown pragmatic development
The proposed visibility distance maximizing and Bit Error Rate (BER) minimizing mechanism have evaluated under different atmospheric conditions including Haze, rain, mist, and fog
To decrease the atmospheric conditions, this study has proposed an iterative optimization algorithm and an enhanced optical communication link design
Summary
The wireless communication has shown pragmatic development. This increased customer attraction has led to significant demand for high Quality of Service (QoS). A resolution of 1280 × 720 pixels YouTube video user requires 2500 Kbps data rates [10]. The collective 500 users video demand requires a 1.25 Gbps data rate. Imagine how this data rate demand is not easy to achieve using the usual RF communications because of the Doppler effect due to movement, frequent handovers, and operational frequencies and bandwidths [11]. The FSO connections are becoming a fascinating alternative for copper, RF, and fiber optic communication techniques, in terms of speed, costing, distance, and mobility
