摘要: Radio access network over fiber (ROF) technology combines wireless and fiber-optic to improve the efficiency of use these technologies. The main problem in designing DWDM transport networks is wavelength assignment light paths. One way solving this algorithm BCO-RWA. However, BCO-RWA has following disadvantage: during calculating route selecting probability, base do not take into account nonlinear four-wave mixing phenomenon. In paper we present an which takes modifications introduced algorithm.
