Wavelength scheduling algorithms in buffer-less optical burst switching networks

One of the major factors that affect the blocking probability at buffer-less optical burst switching (OBS) node is the deployed wavelength scheduling algorithm. In this paper we survey all previously proposed wavelength scheduling algorithms. In addition, we present two new wavelength scheduling algorithms: Max-NGV and Min-AV. The Max-NGV algorithm selects the wavelength channel on which the newly generated void, after the burst transmission, is maximum. On the other hand, the Min-AV algorithm chooses the wavelength channel with the minimum available void. We compare the performance of the newly proposed algorithms to existing ones through simulation experiments. Simulation results suggest that our proposed Min-AV algorithm performs better than all previously proposed wavelength scheduling algorithms in terms of the blocking probability.
