Abstract

In multihop systems of wavelength division multiplexing (WDM) networks, wavelength conversion is required at the conjunction of two lightpaths if they use different wavelengths. In this paper we consider the problem of assigning wavelengths to the lightpaths by using limited number ofwavelengths, so that the overall number ofwavelength conversions in the whole system is minimal. The problem is formulated as a maximum clique cover problem. An approximation algorithm is proposed to solve it. Our proposed theory also illustrates the tradeoff relationship between the number of wavelengths and the number of conversions in the system.
