Abstract
We address the problem of wavelength assignment in
wavelength-division-multiplexing (WDM) networks. One of the major design issues in
this network is the assignment of a limited number of wavelengths among network
stations so that high aggregate capacity can be achieved. We propose what we believe
to be a novel and effective wavelength-assignment algorithm based on a heuristics
approach. The heuristic algorithm takes account of the unique characteristics of the
optical physical constraints, i.e., wavelength-continuity constraints. Compared with
some of the best-known wavelength-assignment algorithms, our algorithm can achieve
lower blocking probability with lower complexity.
