— This paper proposes optical wavelength division multiplexed (WDM) networks with limited wavelength conversion that can efficiently support lightpaths (connections) between nod...
In this paper we present a hybrid model for the demand acceptance variant of the routing and wavelength assignment problem in directed networks, an important benchmark problem in o...
Abstract— Wavelength is one of the most important resources in Wavelength Division Multiplexing(WDM) networks. In optical routing, we are given a set of communication paths (or l...
Abstract—Optical Transport Networks (OTN) must be prepared in terms of better resource utilization, for accommodating unicast and multicast traffic together. Light-trees have be...
