Abstract: The Optical network is a field of transmitting data over light signals across various distances. An increasing number of users in Wavelength Division Multiplexing network increases the blocking probability and Physical layer impairments such as Amplifier Spontaneous Noise, Cross talk, Cross Phase Modulation and Four wave mixing. The proposed Adaptive Most-Shared Impairment Aware Routing and Wavelength Assignment (AMSIR) algorithm effectively utilizes bandwidth and reduces impairments. Simulation result demonstrates that the proposed algorithm reduces blocking probability, increases capacity utilization and minimizes the number of wavelength requirements when compared with First Fit (FF), Ant Colony (ACO) algorithm, Genetic Objective First (GOF) algorithms.
