Routing, Spectrum and Core Assignment on SDM Optical Networks (Invited)
Optical Fiber Communication Conference, 2016Simple and flexible RSCA methods in SDM networks are proposed. They introduce Prioritized Area concept, and two kinds of crosstalk-awareness; Strict Constraint and Best-Effort approaches, and extend/compensate their performance by MIMO based approach.

Joint On-Demand Routing and Spectrum Assignment in Cognitive Radio Networks
2007 IEEE International Conference on Communications, 2007In cognitive radio networks, nodes can work on different frequency bands. Existing routing proposals help nodes select frequency bands without considering the effect of band switching and intra-band backoff. In this paper, We propose a joint interaction between on-demand routing and spectrum scheduling.

Crosstalk-aware Routing and Spectrum assignment in flexible grid networks
2016 IEEE Symposium on Computers and Communication (ISCC), 2016This work presents algorithms for the design phase of flexible grid optical networks considering the impact of in-band channel crosstalk. Due to crosstalk-induced interactions among different connections, malicious high-power signals can potentially spread widely in the network.

Improved Routing and Spectrum Assignment formulations for optical OFDM networks
2016 8th International Symposium on Telecommunications (IST), 2016Efficient resource allocation in OFDM-based optical networks is directly affected by definition and formulations of Routing and Spectrum Assignment (RSA) problem. In this paper, we propose new Binary Linear Programming (BLP) formulations for the RSA problem that provide more efficient resource allocation in comparison with previous formulations. Unlike

Routing, Modulation and Spectrum Assignment using an AI based Algorithm
2019 11th International Conference on Communication Systems & Networks (COMSNETS), 2019There is a need of the networks which can accommodate the requirements of high data rate with low blocking probability. Optical networks are used most commonly as the backbone. They support high data rates, but need to be provisioned with low blocking probability. Due to the use of traditional Wavelength Division Multiplexing (WDM), optical network are

Routing and Spectrum Assignment Algorithm Maximizes Spectrum Utilization in Optical Networks
37th European Conference and Exposition on Optical Communications, 2011This paper proposes a routing and spectrum assignment algorithm for elastic optical networks. The algorithm achieves high utilization of spectrum resources by considering the consecutiveness of common available spectrum slots among relevant fibers.

Routing and Spectrum Assignment in Spectrum Flexible Transparent Optical Networks
2014In this paper the heuristic algorithm for the selection lightpaths in flexible transparent optical networks has been presented. The considered problem of routing and spectrum assignment (RSA) takes into consideration minimizing the length of the transmission distance under spectrum continuity constraints and relationship between the traffic bitrates ...

2019 28th Wireless and Optical Communications Conference (WOCC), 2019
Routing and spectrum allocation (RSA) is one of the key problems in EONs since bandwidth fragmentation generated by establishing the connection dynamically. In this work, we propose a routing and spectrum allocation algorithm based on Maximum Spectrum Completeness (MSC) which selected the completely contiguous frequency of the light-path and avoiding ...
