Routing, Spectrum, and Transponder Assignment in Elastic Optical Networks [PDF]
Journal of Lightwave Technology, 2015 Backbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable transponders (SBVTs) that support the simultaneous generation of multiple optical carriers.

Cognitive Radio Routing and Optimal Spectrum Assignment Algorithm
Advanced Materials Research, 2011 Aiming to the shortcoming of traditional route protocols in cognitive radio networks, cognitive radio routing and optimal spectrum assignment (CRRSA) algorithm was proposed. In this paper, we consider the situation that non-interfering among the adjacent jump, and present the optimal allocation of available spectrum, and then calculate the bandwidth of
