Multiple Channel Network Scheme employing Hybrid FSO and NB-PLC for smart city environment

The practical design of Free-space optical communications (FSOs) faces significant challenges due to atmospheric turbulence and pointing errors. To overcome these obstacles, a hybrid technology combining FSO with NB-PLC scheme has been analyzed in this paper. The study evaluates the area coverage of a hybrid model of Power Line Communication (PLC) and Free Space Optical Communication (FSO) by measuring the Successful Transmission Probability (STP) and probability of error. The analysis assumes that the PLC channel undergoes Rayleigh fading, while FSO links are modelled using the Gamma-Gamma distribution. An algorithm is used to weigh each link by its Successful Transmission Probability (STP) and select the best possible path using the Single Channel Selection scheme (SCS). The Monte Carlo simulation results demonstrate that the proposed system is highly advantageous in smart city environments where channel fading is dynamic.
