Analysis of Blocking Probability in WDM Networks

Wavelength assignment algorithm is one of the important components of routing and wavelength assignments problem in WDM networks. This problem helps in the minimization of the blocking probability of the network. In this paper we have reviewed the wavelength assignment problem and discussed the history of this problem with a good literature review. Depending upon the literature and history of this problem we can conclude that the work can be done in this field for the minimization of the blocking probability of the network leading to the blocking free environment. The blocking probability can be calculated for the network with wavelength conversion and without wavelength conversion
