A Fuzzy Logic System-Based Multidimensional Integrated Routing and Wavelength Assignment Method in Optical Network-on-Chip (ONoC)

Abstract

In Optical Network-on-Chip (ONoC), both routing and wavelength assignment have an impact on the Optical Signal-to-Noise (OSNR), which further influence the power efficiency and scalability. In this work, we propose a multidimensional Integrated RWA method based on the fuzzy logic system (named as I-RWA) which considers routing and wavelength assignment. OSNR, traffic distribution, waiting delay and wavelength utilization are taken into consideration at the same time. The effect of wavelength assignment on OSNR is also discussed. The evaluation results show that the proposed method I-RWA can obtain the best performance in OSNR and is feasible to be adapted for other more performance factors.
