Wavelength assignment to lightpaths for minimal wavelength conversions in multihop WDM networks
In multihop wavelength division multiplexing systems, a connection between two communication nodes consists of one or more lightpaths. A wavelength conversion is required at the j...

Wavelength Assignment for Dynamic Traffic in Multi-fiber WDM Networks
Wepropose an on-line wavelength assignment algorithm for multi-jiber WDM networks, in which lightpaths are established and released dynamically. For a given number of jibers per l...
