Abstract: | This paper proposes and evaluates a four-wave mixing (FWM) aware evolutionary programming algorithm for dynamically setting
up lightpaths in an optical wavelength division multiplexed network (WDM network). The proposed algorithm also considers the
effect of amplified spontaneous emission noise (ASE noise) on a lightpath during propagation of the optical signal from any
source to the intended destination. As crosstalk due to FWM and ASE noise are two transmission impairments that degrade the
quality of optical signal even at low to medium data rates, it is mandatory for an algorithm for dynamic routing and wavelength
assignment in a WDM network to consider the effect of these two impairments on the lightpath to be established. The distinguishing
feature of the proposed algorithm is that it is based on an initial population of a single individual and uses a fitness function
that is expressed in terms of the number of hops, path cost, variance contributions due to FWM crosstalk, amplifier noise,
and different beat noises at the receiver. The performance of a newly introduced FWM aware priority-based wavelength assignment
technique is compared with few of the existing wavelength assignment techniques in the present work. |
