Performance Comparison of Optical Wireless Communication Using Gray Relational Analysis

Abstract

In this study, Indian Optical Wireless Communication (IOWC) is examined as a short-range method for transferring data at high rates. It is rapidly gaining popularity as an effective method, with an optical transmitter at the IOWC terminal and a receiver included. For example, it can be used in tall buildings separated by several hundred meters, where light beams propagate through the atmosphere and convey information to the recipient. IOWC has several advantages over its competitors, most notably its quick setup, free-of-charge licensing, and lightweight, high-capacity communications. However, IOWC still faces many challenges, including improving communication efficiency in adverse weather conditions or during construction. In the field of underwater acoustic communication, great progress has been made, but IOWC is still better than traditional audio communication systems due to its significantly lower power consumption and ability to provide simple computational problems for short-range wireless links. IOWC has many potential applications, including in Indian coastal waters. The gray relational analysis (GRA) method is simple in calculations and optimizations, and research shows that it is easy to extend this proposed method for problems with more than two answers. To determine the material and life strategies in a one-dimensional array, a method provides multidimensional alternatives based on Taguchi using gray correlation analysis. The optimization design is done on a top cap with a thin wall section unique to TWBs structures. The gray relational analysis method can be used to describe the alternative and evaluation parameters in optical wireless communication. As far as the optical wireless communication APM-EDM process is concerned, alternatives include Lamina Atlas NT-42C1-0484, AOP LED Corp PU-5WAS, Kingbright AADI-9090QB11Gitek/3, LGLB-313E, Toshiba TL12B01 (T30), and Lumex SML-LX1610USBC. The evaluation parameters are wavelength (nm) and luminous flux (Im). From the final result, it is seen that AOP LED Corp PU-5WAS got the first rank, whereas Toshiba TL12B01 (T30) has the lowest rank
