—In this paper, we formulate an optimization problem for the design of light-tree based logical topology in Wavelength Division Multiplexing (WDM) networks. The problem is compri...
Orthogonal Frequency Division Multiplexing (OFDM) has been recently proposed as a modulation technique for optical networks, due to its good spectral efficiency and impairment tole...

- Rapid progress in deployment of national and regional optical network infrastructures holds the promise to provide abundant, inexpensive bandwidth to scientific communities. The ...
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...
High efficiency in capacity utilization and fast restoration are two primary goals of survivable design in optical networks. Shared backup path protection has been shown to be effi...
