Attack-aware Lightpath Provisioning in Elastic Optical Networks with Traffic Demand Variations
Manousakis, Konstantinos; Panayiotou, Tania; Kolios, Panayiotis; Tomkos, Ioannis; Ellinas, Georgios (2019)This work considers lightpath provisioning in elastic optical networks with traffic demand variations while accounting for the impact of jamming attacks. Traffic requests are modeled based on their variation in traffic and ...

Charging Policies for PHEVs used for Service Delivery: A Reinforcement Learning Approach
Panayiotou, Tania; Chatzis, Sotirios P.; Panayiotou, Christos; Ellinas, Georgios (2018)This work examines a cost optimization problem for plug-in hybrid electric vehicles (PHEVs) used for service delivery, in the presence of energy consumption uncertainty. For the cost optimization problem, an optimal policy ...

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 ...
