Routing and Spectrum Allocation in OFDM-Based Optical Networks with Elastic Bandwidth Allocation
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Orthogonal Frequency Division Multiplexing (OFDM) has been recently proposed as a modulation technique for optical networks, due to its good spectral efficiency and impairment tolerance. Optical OFDM is much more flexible compared to traditional WDM systems, enabling elastic bandwidth transmissions.

Protection, Routing, Spectrum and Core Allocation in EONs-SDM for Efficient Spectrum Utilization
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019The use of protection in elastic optical networks (EONs) with spatial division multiplexing (SDM) can lead to under-utilization of the spectrum, since a high number of resources is reserved for protection. In this paper, we propose an algorithm that employs minimum interference routing, FIPP p-cycle, optical traffic grooming, and spectrum overlap to ...

A study of the routing and spectrum allocation in spectrum-sliced Elastic Optical Path networks
2011 Proceedings IEEE INFOCOM, 2011In OFDM-based optical networks, multiple subcarriers can be allocated to accommodate various size of traffic demands. By using the multi-carrier modulation technique, subcarriers for the same node-pair can be overlapping in the spectrum domain. Compared to the traditional wavelength routed networks (WRNs), the OFDM-based Spectrum-sliced Elastic Optical

ACO-based routing and spectrum allocation in flexible bandwidth networks
Photonic Network Communications, 2013Optical networks with flexible bandwidth provisioning are a very promising networking architecture. It enables efficient resource utilization and supports heterogeneous bandwidth demands. In this paper, we focus on the dynamic routing and spectrum allocation (RSA) problem which emerges in such networks and propose a novel dynamic RSA algorithm by means

Joint Routing and Scheduling in WMNs with Variable-Width Spectrum Allocation
IEEE Transactions on Mobile Computing, 2013This paper addresses, in the context of wireless network design, the problem of optimally partitioning the spectrum into a set of nonoverlapping channels with nonuniform spectrum widths. While narrower bands split the total available spectrum into more nonoverlapping channels allowing more parallel concurrent transmissions, wider spectrum bands yield ...

Relative cost routing and spectrum allocation in elastic optical networks
Journal of Optical Communications and Networking, 2020Elastic optical networks (EONs) are being used to adapt to the recent rapid changes in traffic behavior and the exponential growth in bandwidth demand. Routing and spectrum allocation (RSA) is one of the most important determining factors of the design, performance, and operation of EONs.
