Quality Aware Design and Analysis of FSO Link in Wireless Optical System

Abstract

Wireless optical system has an astounding potential to support the next generation massive data transfer requirements. Free space optics (FSO) is one of such technology used for long distance communication. Its a compelling alternative or complementary solution to commonly deployed fiber optics and wireless radio-frequency links. It provides a viable solution to the first/last mile problem to the broadband communication. Despite advantages, it remains sensitive to environmental conditions, like fog, rain, snow, etc. This paper focuses on the performance analysis of the FSO link held down to various atmospheric conditions. Also, a novel quality based network routing on various quality parameters are used for the evaluation of connection availability. Link margin (LM) is used as one of the collective quality parameters for the design and analysis of FSO link. LM based routing is used for finding the network route which provides a high reliability to the FSO link even for the adverse weather phenomenon.
