Abstract—In this paper we consider routing and wavelength assignment in wavelength-routed all-optical networks with circuitswitching. The conventional approaches to address this ...
The problem of routing and wavelength assignment (RWA) in wavelength division multiplexing (WDM) optical networks consists in routing a set of lightpaths and assigning a wavelength...

We address the problem of efficient circuit switching in wide area networks. The solution provided is based on finding optimal routes for lightpaths and semilightpaths. A lightpat...
An efficient and general graph-theoretic model (the Wavelength-Graph (WG)) has been proposed which enables solving the static Routing and Wavelength Assignment (RWA) problems in Mu...
—In many applications, it is a basic operation for the sink to periodically collect reports from all sensors. Since the data gathering process usually proceeds for many rounds, i...
