A Study of Dynamic Routing and Wavelength Assignment with Imprecise Network State Information
In large networks, maintaining precise global network state information is almost impossible. Many factors, such as non-negligible propagation delay, infrequent state updates due ...

Dynamic Routing and Wavelength Assignment in WDM Networks with Ant-Based Agents
In this paper, we propose an ant-based algorithm for dynamic routing and wavelength assignment (RWA) in WDM optical networks under the wavelength continuity constraint. By adopting...

A Forward-Backward Optical Wavelength Path Establishment Scheme with Low Blocking Probability in WDM Networks
—we study dynamic routing and wavelength assignment scheme when there are any available wavelengths on a route in the wavelength-routed networks. An optical wavelength path reque...
