Abstract :
In this paper, the problem of integrated routing and wavelength assignment in wavelength division multiplexing (WDM) networks is studied. We propose a colored multigraph model for the temporarily available wavelengths. Based on this colored multigraph model, a polynomial time algorithm with complexity O(N2) is also proposed to develop an integrated dynamic routing and wavelength assignment, where N is the number of nodes in a WDM network. Simulation results show that the proposed algorithm achieves lower the connecting blocking probability than the existing ones.
