Routing and Wavelength Assignment in WDM Rings with Heterogeneous Wavelength Conversion Capabilities
14 years 26 days ago
—In this paper, we study the routing and wavelength assignment (RWA) tasks in WDM rings with heterogeneous wavelength conversion capabilities. By heterogeneous, we mean that diff...
