Since light-paths are the basic connections in wavelength routed networks, their effective
establishment is very important. Routing and Wavelength Assignment (RWA) techniques …

This work proposes two different distributed strategies for provisioning lightpaths in the
presence of optical physical-layer impairments in GMPLS networks. The first approach is a …

This work proposes a novel routing algorithm for transparent optical networks, which is
based on the ant colony optimization (ACO) meta-heuristics. It takes into consideration the …

In this study, we solve the routing and wavelength assignment problem considering physical
constraints of Amplified Spontaneous Emission in erbium-doped fiber amplifiers and …

Wavelength Routed Photonic Networks (WRPNs) with a fully distributed control plane
promise to satisfy the increasing infrastructure needs of upper layer clients regarding …

In this paper, a tabu search based hyper heuristic is applied to the routing and wavelength
assignment problem, considering physical impairments caused by Amplified Spontaneous …
