Wavelength detection in FBG sensor network using tree search DMS-PSO

Abstract

As the number of fiber Bragg gratings (FBGs) increases, the conventional peak detection method will be unsuitable to detect Bragg wavelengths of FBG sensors in a wavelength-division-multiplexed (WDM) network. To solve this problem while achieving a higher accuracy at reduced computation cost, a novel tree search dynamic multiswarm particle swarm optimizer (TS-DMS-PSO) is developed. The TS-DMS-PSO yields better results with less computation cost based on the simulations (codes are available from the second author)
