“…In literature [1], [8]- [14], to suppress the FWM crosstalk in optical WDM systems, several unequally spaced channel allocation (USCA) algorithms have been proposed. An optimum-USCA (O-USCA) algorithm ensures if the frequency separation of any two channels is different from any other pair of channels no FWM crosstalk will ever be generated at any of the channel frequencies [11].…”

“…An optimum-USCA (O-USCA) algorithm ensures if the frequency separation of any two channels is different from any other pair of channels no FWM crosstalk will ever be generated at any of the channel frequencies [11]. However, the algorithms [8]- [14] have the drawback of increased optical bandwidth requirement compared to equally spaced channel allocation (ESCA). This paper proposes, a fractional bandwidth channel allocation algorithm taking into consideration the concept of Optimal Golomb ruler sequences [7], [15]- [17].…”

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 fourwave 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.

“…There is still very high probability that FWM signals may fall into the WDM channels, resulting in severe crosstalk. In an attempt to reduce the FWM effect in WDM systems, many unequally spaced channel allocation methods [2][3][4][5] are proposed. However, they resulted in the increase of bandwidth requirement compared to equally spaced channel allocation.…”

Nowadays, nature-inspired metaheuristic algorithms are most powerful optimizing algorithms for solving the NP-complete problems. This paper proposes three approaches to nd near-optimal Golomb ruler sequences based on nature-inspired algorithms in a reasonable time. The optimal Golomb ruler (OGR) sequences found their application in channel-allocation method that allows suppression of the crosstalk due to four-wave mixing in optical wavelength division multiplexing systems. The simulation results conclude that the proposed nature-inspired metaheuristic optimization algorithms are superior to the existing conventional and nature-inspired algorithms to nd near-OGRs in terms of ruler length, total optical channel bandwidth, computation time, and computational complexity. Based on the simulation results, the performance of proposed di erent nature-inspired metaheuristic algorithms are being compared by using statistical tests. The statistical test results conclude the superiority of the proposed nature-inspired optimization algorithms.
