• Green video delivery in LTE-based heterogeneous cellular networks 

      Galanopoulos A., Iosifidis G., Argyriou A., Tassiulas L. (2015)
      In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ...
    • Tile caching for scalable VR video streaming over 5G mobile networks 

      Liu K., Liu Y., Liu J., Argyriou A. (2021)
      Currently, VR video delivery over 5G systems is still a very complicated endeavor. One of the major challenges for VR video streaming is the expectations for low latency that current mobile networks can hardly meet. Network ...
    • Video Delivery in Dense 5G Cellular Networks 

      Argyriou A., Poularakis K., Iosifidis G., Tassiulas L. (2017)
      One of the main challenges for mobile network operators today is the efficient delivery of mobile VoD services. In order to satisfy their requirements, we must revolutionize the way we manage the densely deployed resources ...
    • Video delivery over heterogeneous cellular networks: Optimizing cost and performance 

      Poularakis, K.; Iosifidis, G.; Argyriou, A.; Tassiulas, L. (2014)
      Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ...
