We study the problems of routing and wavelength converter placement in optical networks with sparse wavelength conversion. We propose a new dynamic routing algorithm with two new path cost functions based on the concept of least-load routing LLR with sparse converter placement, and we discuss the application of genetic algorithms GAs to determine the optimal location of wavelength converters so that the call-blocking probability is minimized.

Simulation results show that the proposed dynamic routing algorithms perform significantly better than shortest-path SP routing and fixed-alternative routing FAR in terms of the call-blocking probability.

The GA model is able to obtain a nearly optimal solution of the wavelength converter placement problem within a reasonable time, and its performance is better than that of two other popular heuristic placement algorithms.
