Dynamic Traffic grooming in hybrid elastic optical and WiMAX networks

Abstract

Abstract Designing low cost scalable networks is driven by increased internet traffic and high bandwidth demand. Optical networks combined with WiMAX forming a hybrid network is one such structure. The existing Wavelength Division Multiplexed Passive Optical Networks suffer from huge bandwidth wastage when the demands are very small compared to the channel capacity. To overcome this drawback, we have replaced passive optical network with an elastic optical network. The routing and resource allocation algorithms are formulated for this hybrid network. Our proposed algorithms efficiently utilize channel capacity and network resources.
