Design method access network radio over fiber

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