Optimization of Wirless Optical Communication System with Placement of Relay Using Shuffled Frog Leaping Algorithm: Recent Perspectives

Wireless Optical communication (WOC) is improved using relay assisted transmission which exploits
multiple shorter hops that gives a better performance gain. Relay assisted transmission is utilized as a
mitigation tool in combating atmospheric turbulence occurring in the communication channels. The
main aim is to minimize the outage probability and optimize relay locations for parallel and serial FSO
relaying. In this paper we address the major limiting factor for links measuring more than a kilometer;
the error rate performances is dismal and therefore relay assisted transmission is employed to combat
this shortcoming. The focus of this study is on considering the channel model, which takes into
account both path-loss and turbulence-induced fading. The locations of the relay are found out using
different algorithms and then compared to find out the best optimized result.
