    • 5GOS: Demonstrating multi-domain orchestration of end-to-end virtual RAN services 

      Camps-Mur D., Canellas F., Machwe A., Paracuellos J., Choumas K., Giatsios D., Korakis T., Kouchaksaraei H.R. (2020)
      Despite recent progress in orchestration of Virtual Network Functions (VNFs) and in multi-technology SDN connectivity, the automated provisioning of end-to-end network services composed of virtual functions deployed across ...

    • Building virtual 802.11 testbeds towards open 5G experimentation 

      Kousias K., Katsalis K., Stavropoulos D., Korakis T., Tassiulas L. (2016)
      Together with recent advancements in Radio Access Network (RAN) technologies, Wi-Fi is expected to be at the center of research on the subject of ubiquitous wireless connectivity, towards building the new 5G ecosystem. ...

    • Cooperation and information replication in wireless networks 

      Poularakis K., Tassiulas L. (2016)
      A significant portion of today's network traffic is due to recurring downloads of a few popular contents. It has been observed that replicating the latter in caches installed at network edges-close to users- can drastically ...

    • Experimental evaluation of a Follow-me MEC Cloud-Native 5G network 

      Tsourdinis T., Makris N., Korakis T. (2021)
      Cloud-native approaches for network functions In the 5G context have been embraced by the community, as they allow flexible management, reconfiguration and monitoring of the network in an end-to-end manner. As network ...

    • 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 ...

    • Joint EPC and RAN Caching of Tiled VR Videos for Mobile Networks 

      Liu K., Liu Y., Liu J., Argyriou A., Ding Y. (2019)
      In recent years, 360-degree VR (Virtual Reality) video has brought an immersive way to consume content. People can watch matches, play games and view movies by wearing VR headsets. To provide such online VR video services ...

    • MEC service placement over the fronthaul of 5G cloud-RANs 

      Passas V., Makris N., Nanis C., Korakis T. (2019)
      Radio Access Network (RAN) disaggregation is transforming mobile networks, as it allows the single click instantiation of base stations in the Cloud, and can potentially ease the integration of heterogeneous technologies ...

    • Portfolio Theory Application for 5G Heterogeneous Cloud-RAN Infrastructure 

      Miliotis V., Makris N., Passas V., Korakis T. (2020)
