Optical Technologies have now emerged as the winning solution for long distance transmissions due to very large bandwidth and low attenuation. Research in energy-efficient optical networking focuses the reduction of energy consumption in Information and Communication Technology. It remains an exciting and essential challenge to devise new techniques in optical networking to offer energy-efficient...
In this paper, we present a dynamic energy efficient routing and spectrum assignment algorithm with regenerator placement (RP) capability for elastic optical networks. In this algorithm, a virtual graph is considered for a given network topology graph, whereby the cost functions of virtual graph is computed according to the energy consumption of the corresponding links and intermediates routers. Furthermore,...
