Locusts Spiral Navigation Algorithm Enabled High-Speed Data Communication Network for Free Space Optics

Over the past two decades, the proliferation of data communication devices has significantly expanded to raise the standard of living for the majority of people. However, the integration of multiple devices into a limited space requires significant bandwidth capacity when building densely connected networks. In addition, conventional systems increase synchronization errors and high operational expenditures. Therefore, to mitigate the limitations this research offers a Locusts Spiral Navigation Algorithm enabled Orthogonal Frequency-Division Multiplexing for high-speed data communication network in free space optics (LSN-OFDM-FSO). The proposed model utilizing the LSN algorithm effectively selects the best phasor weight factors with minimal Peak Average Power Ratio (PAPR) value. Moreover, the combination of Wavelength Division Multiplexing and Mach–Zehnder Modulator systems ensure high-speed connectivity with maximum transmission capacity. When compared with other existing modulation methods, the LSN-OFDM-FSO offers less Bit Error Rate for a Free space optics length of 6 km. Additionally, the proposed model has less penalty total power of -966.674 dB, and total power of -33.2618 dBm. On the other hand, in terms of energy analysis, for 64 OLTs, the proposed model consumes a total energy of 9.29, and the ONU consumes less energy of 77.04. Moreover, the proposed system is well-suitable for high-speed data communication networks, with minimum information loss and delay.
