Adaptive FLP - A New Wavelength Converter Placement Scheme for Optical Networks with Sparse-Partial Wavelength Conversion

In this paper it is proposed a new wavelength converter placement scheme called Adaptive First Load Priority, useful for designing and planning of optical networks with sparsepartial wavelength conversion architecture. The adaptive FLP is an extension of the FLP (First Load Priority) placement scheme proposed by authors in a previous work [11]. It was conceived with the aim of decreasing the number of WCRs (Wavelength Converter Router) used by FLP scheme. Initially, we provide a performance evaluation of FLP working in different scenarios.. Comparing to others wavelength converter placement schemes proposed in the literature like MBPF [9], TOT [8], XC [5] and to partial wavelength conversion, our results show that FLP achieves better performance in all scenarios studied, very close to that one achieved with a full-complete wavelength conversion architecture. Thus, we introduce the Adaptive FLP scheme comparing its performance to XC and FLP schemes. Results achieved by applying adaptive parameter equal to 10%, show a reduction of 42% (5 WCRs) in terms of WCRs required by simple FLP in the the scenarios studied..
