AN EFFICIENT WAVELENGTH ASSIGNMENT SCHEME BASED ON PERFORMANCE METRICS FOR WDM OPTICAL NETWORKS
Keywords:Dispersion, QoS, Routing Wavelength assignment strategy, WDM networks
Dispersion in fiber optic is wavelength dependent and it degrades the quality of service (QoS) in an optical network. To overcome this problem, proposed an efficient QoS oriented path length based wavelength assignment strategy which assign the wavelength according to the path length. In this approach, the connection requests with shorter lightpath are assigned the wavelengths having higher dispersion and the wavelengths having lesser dispersion are assigned to the lightpaths with larger distance. This strategy is the optimum choice for large size networks where the number of requests are high.
