Network Coding for Security Against Eavesdropping Attacks in Elastic Optical Networks
Savva, Giannis; Manousakis, Konstantinos; Ellinas, Georgios (Springer International Publishing, 2020)In this work, routing and spectrum allocation (RSA) algorithms together with network coding (NC) are proposed for elastic optical networks. NC has been used in optical networks for protection against link failures and also ...

On learning bandwidth allocation models for time-varying traffic in flexible optical networks
Panayiotou, Tania; Manousakis, Konstantinos; Chatzis, Sotirios P.; Ellinas, Georgios (2018)We examine the problem of bandwidth allocation (BA) on flexible optical networks in the presence of traffic demand uncertainty. We assume that the daily traffic demand is given in the form of distributions describing the ...

Parallel Ant Colony Optimization for the Electric Vehicle Routing Problem
Mavrovouniotis, Michalis; Li, Changhe; Ellinas, Georgios; Polycarpou, Marios (2019)Parallelizing metaheuristics has become a common practice considering the computation power and resources available nowadays. The aim of parallelizing a metaheuristic is either to increase the quality of the generated ...

Physical Layer-Aware Routing, Spectrum, and Core Allocation in Spectrally-Spatially Flexible Optical Networks with Multicore Fibers
Savva, Giannis; Ellinas, Georgios; Shariati, Behnam; Tomkos, Ioannis (2018)In this work, efficient routing, spectrum, and core allocation (RSCA) techniques are proposed for spatial division multiplexed (SDM) elastic optical networks (EONs) utilizing multicore fibers (MCFs). These techniques provide ...
