The Constrained-Routing and Spectrum Assignment Problem : Polyhedral Analysis and Algorithms
, 2022 In this thesis, we study a variant of the Routing and Spectrum Assignment problem (RSA), namely the Constrained-Routing and Spectrum Assignment (C-RSA). The C-RSA problem is a key issue when dimensioning and managing a new generation of optical networks, called spectrally flexible optical networks. The C-RSA can be stated as follows.

Hybrid Optimized Approaches for Routing and Resource Reservation Protocols in Optical Networks
IEEE Photonics Journal, 2021 We have proposed hybrid approaches to solve dynamic provisioning problems in fixed-grid and elastic optical networks (EON). The proposed approaches use the information from the optimization models, which normally are used to solve static problems, to ...

A cross-layer heuristic algorithm for addressing shadowing problem in optical attocell networks [PDF]
, 2020 The performance of visible light communication (VLC)-based optical attocell networks degrades due to shadowing caused by opaque objects. In order to improve reliability, we propose a cross-layer algorithm to find the optimal routing and resource ...
