The signal quality degradation, which occurs due to the aspects of fiber attenuation, splitter switch, and amplified spontaneous noise in erbium-doped fiber amplifier, may substantially erode the performance of optical communications. Among the above-mentioned factors, the physical-layer impairments may significantly weaken the signal quality at the(More)
The immunization algorithm is from the theory of complex network. The algorithm is simple, highly feasible based on scale-free network model. This paper uses a targeted immunization for optical network energy issues. This paper selects the service to be the operator and to save energy through node immunization. The simulation results show the algorithm can(More)
