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 ...
