Abstract
Wireless Optical Communications (WOC) systems are advantageous over other competing technologies and are attractive to provide broadband services due to their inherent wide bandwidth, easy deployment and no license requirement. A Hybrid Differential Evolutionary (HDE) algorithm, in which both trial vector generation strategies and their associated control parameter values are gradually self-adapted by learning from their previous experiences in generating promising solutions is introduced to determine optimal relay locations in serial and parallel WOC relaying so as to minimize the outage probability and then quantify performance improvements obtained through optimal relay placement. The effect of wavelength on the performance of a WOC link has been evaluated and the variation of outage probability has been compared with the power margin Pm of the WOC link.
