Abstract
Wavelength Assignment (WA) is an important issue of the WDM (Wavelength Division Multiplexing) network light path transmitting designation for the purpose of designing the WDM network with high speed data transmission and high quality. This article proposes a mathematical model for the light path designation of WDM wavelength conversion with Markov process method for wavelength assignment (MPM-WA). Finding the probability for choosing the suitable wavelength is used for light path connection of WDM with wavelength conversion nodes on a ring network system. From the numerical experiment results, the proposed method can give the blocking probability better than First-Fit WA, Random WA, and Most-Used WA wavelength assignment methods. Moreover, the proposed method can create light paths by applying the Fixed-Alternate path routing method for WDM ring network efficient usage.
