ABSTRACT: The analysis of WDM
(Wavelength-Division Multiplexing) optical network is essential to have the
routed wavelength blocking probability with the conversion of wavelength using
techniques. In this paper, an enhanced analytical model is proposed to evaluate
the blocking performances in topology network and to improve the performances
of reduction of blocking probability. The variation of probability is based on
the wavelength and load used in the network. The conversion is carried out with
the support of optical backbone of the inherent flexibility of the network
using the proposed IMCA in Sparse-Partial Wavelength Conversion (SPWC)
architecture. It reduces the number of converters significantly with efficient
process and provides placement scheme of wavelength converters in the network.
The proposed model utilizes the network with the assignment and routing of
wavelength using dynamic process of assignment algorithm. The proposed model
provides dynamic and static routing process with the range limit to have a
minimum conversion for the same probabilities of blocking. The proposed system
analysis and the simulation results show the better performances in faster
coverage, minimum number of conversions, blocking probability improvement for
high load.
