Abstract :
In this paper, a novel Fuzzy logic controller is proposed to solve the quality of service (QoS) aware dynamic routing and wavelength assignment (DRWA) problem for a wavelength division multiplexing (WDM) optical network. This paper proposes a novel quality of service aware Fuzzy logic controlled dynamic routing and wavelength assignment algorithm (QoS-FDRWA), where the minimum cost path is chosen by a Fuzzy Rule Based Inference System (FRBS). The proposed QoS-FDRWA incorporates QoS aware network transmission parameters such as latency, physical length of the link, data packet loss, number of hops, and wavelength availability status in the path. The proposed work integrates the DRWA algorithm with two fuzzy logic controllers (FLCs) to minimize the average blocking probability and average execution time.
