: A fundamental problem in communication networks is wavelength assignment (WA): given a set of routing paths on a network, assign a wavelength to each path such that the paths wit...
— We study wavelength assignment for lightpaths over WDM rings to minimize the SONET ADMs used. This problem has attracted much attention recently. However, its computation compl...
We consider the problem of minimizing the number of ADMs in optical networks. All previous theoretical studies of this problem dealt with the off-line case, where all the lightpat...

The construction of light-trees is one principal subproblem for multicast routing in sparse splitting Wavelength Division Multiplexing (WDM) networks. Due to the light splitting co...
The increasing popularity of all-optical networks has led to extensive research on the routing and wavelength assignment problem, also termed as the Routing and Path Coloring probl...
