Analysis of wavelength conversion in wavelength routed WDM networks

In order to achieve the improved blocking performance of wavelength routed WDM networks, wavelength conversion can be implemented at nodes. The paper evaluates the performance of the network in terms of blocking probability with and without wavelength conversion. The analysis and comparison for wavelength conversion and without wavelength conversion has been undertaken for static and dynamic traffic. It is observed that with wavelength conversion blocking probability reduces significantly. The underlying system model is presented for wavelength conversion and without wavelength conversion. Simulation results also suggest the optimal value of resources for each case.
