A Novel Soft–Computing Algorithm for Channel Allocation in WDM Systems
نویسندگان
چکیده
Nature–inspired algorithms are the most powerful algorithms for optimization problems. This paper presents a novel optimization channel allocation algorithm inspired by the flash pattern of fireflies that allows suppression of the four–wave mixing (FWM) crosstalk while maintaining channel bandwidth. It is composed of a fractional bandwidth channel allocation algorithm by using the concept of Optimal Golomb ruler (OGR) sequences. The simulation results conclude that the proposed novel optimization algorithm outperforms the other two existing conventional algorithms i. e. Extended Quadratic Congruence (EQC) and Search Algorithm (SA) in terms of the total optical bandwidth.
