Wavelength pre-assignment collision schedule for wavelength-routed optical networks

A novel wavelength assignment scheme called the wavelength pre-assignment collision schedule (WPCS) is proposed for wavelength-routed networks.The WPCS pre-assigns the wavelength at the forward detection phase, and schedules the potential collision by priority.The potential collision is scheduled at the forward detection phase and the blocking of the wavelength assignment is reduced.Simulation is conducted with several other existing schemes.The numerical results show that WPCS performs better than other schemes in blocking probability under various traffic conditions.
