Blocking probability of algorithms for different wavelength assignment in optical ring network

The blocking probability of the network is presented based on total number of wavelengths in the eight node ring network. Here, we have varied the number of available wavelength and calculate the blocking probability. Blocking probability varied from 0.8 to 0.2, 0.7 to 0.1 as number of available wavelength changed from 1 to 9 for most used and wavelength conversion algorithm, respectively. So as the number of available wavelength increases the blocking probability decreases in ring network. Also the performance of the wavelength conversion algorithms is best as compared to most used algorithm but there is burden of using expensive hardware.
