• Federated-Learning-Driven Radio Access Networks 

      Foukalas F. (2022)
      In this work, we present federated learning (FL) driven radio access mechanisms, which can be employed at the future radio access networks (RANs) to achieve high accuracy rather than data rate that was the objective in ...
    • Optimal Dynamic Allocation of Collaborative Servers in Two Station Tandem Systems 

      Papachristos I., Pandelis D.G. (2019)
      We consider two-stage tandem queueing systems with one dedicated server in each station and a flexible server that can serve both stations. We assume exponential service times, linear holding costs accrued by jobs present ...
